I need to execute some powershell code from a web api which I have deployed in an Azure App Service. I couldn't achieve to se 'Set-ExecutionPolicy' because I need to set it to unrestricted but I get an error
File D:\home\powershell\teams_v2.psm1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at http://go.microsoft.com/fwlink/?LinkID=135170
.
I have the following code
using (Runspace runspace = RunspaceFactory.CreateRunspace())
{
runspace.Open();
var script = String.Format(#"Import-Module 'D:\home\powershell\teams_v2.psm1'
connect-teamsservice -user admin#contoso.onmicrosoft.com -tenant contoso.onmicrosoft.com
new-Team -displayname '{0}' -description '{1}' -smtpaddress '{2}' -alias '{3}' -type 'private'",
group.Name, group.Description, String.Format("{0}#contoso.onmicrosoft.com", group.MailNickName), "team");
RunspaceInvoke scriptInvoker = new RunspaceInvoke();
// set powershell execution policy to unrestricted
//scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted");
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(script);
// add an extra command to transform the script
// output objects into nicely formatted strings
// remove this line to get the actual objects
// that the script returns. For example, the script
// "Get-Process" returns a collection
// of System.Diagnostics.Process instances.
pipeline.Commands.Add("Out-String");
// execute the script
Collection <PSObject> results = pipeline.Invoke();
// close the runspace
runspace.Close();
// convert the script result into a single string
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
stringBuilder.AppendLine(obj.ToString());
}
}
How can I achieve this to correctly load the ps module and use its functions.

I am writing a service which controls docker containers. I want to have the mounted volume as an Azure share, and thus need to use the SMB Global Mapping. If I use the usual WNetAddConnection2A then I can mount the share just fine in my code, but the containers cannot see it as it is not "global". I can't find source for the PowerShell New-SmbGlobalMapping command (is there a way to see it?) and I can't find a suitable API to call. I hope someone knows the magic incantation I can put in my .NET code.

PowerShell uses WMI
In your case, it calls
Create method of the MSFT_SmbMapping class (MSFT_SmbGlobalMapping exactly)
You can use WMI Code Creator to generate/test C# code
EDIT : Test with PowerShell.Create
Test as Admin ("requireAdministrator" in manifest) on Windows 10
Test code (C#, VS 2015) =>
// PowerShell calls CredUIPromptForCredentialsW to display the User/Password dialog (you can call it with P/Invoke if needed)
string sUser = "user#provider.com";
string sPassword = "myPassword";
System.Net.NetworkCredential networkCredential = new System.Net.NetworkCredential(sUser, sPassword, null);
System.Security.SecureString securePassword = new System.Security.SecureString();
foreach (var c in networkCredential.Password)
securePassword.AppendChar(c);
// Add reference to :
// C:\Program Files (x86)\Reference Assemblies\Microsoft\WindowsPowerShell\3.0\System.Management.Automation.dll
// Add :
// using System.Management.Automation;
PSCredential psCredential = new PSCredential(networkCredential.UserName, securePassword);
// Error handling must be improved : if I pass an invalid syntax for "RemotePath" or not launched as Admin,
// nothing happens (no error, no result) (on Windows 10)
string sLocalPath = "Q:";
string sRemotePath = "\\\\DESKTOP-EOPIFM5\\Windows 7";
using (var ps = PowerShell.Create())
{
ps.AddCommand("New-SmbGlobalMapping");
ps.AddParameter("LocalPath", sLocalPath);
ps.AddParameter("RemotePath", sRemotePath);
ps.AddParameter("Credential", psCredential);
//ps.AddParameter("RequireIntegrity", false);
//ps.AddParameter("RequirePrivacy", false);
try
{
System.Collections.ObjectModel.Collection<PSObject> collectionResults = ps.Invoke();
foreach (PSObject psObl in collectionResults)
{
Console.WriteLine("Status : {0}", psObl.Members["Status"].Value.ToString());
Console.WriteLine("Local Path : {0}", psObl.Members["LocalPath"].Value.ToString());
Console.WriteLine("Remote Path : {0}\n", psObl.Members["RemotePath"].Value.ToString());
}
}
catch (ParameterBindingException pbe)
{
System.Console.WriteLine("\rNew-SmbGlobalMapping error : {0}: {1}",
pbe.GetType().FullName, pbe.Message);
}
}
// To get and remove the test mapping in PowerShell :
// Get-SmbGlobalMapping
// Remove-SmbGlobalMapping -RemotePath "\\DESKTOP-EOPIFM5\Windows 7" -Force
I want to know if it is possible to create a new Powershell Runspace object from an old one.
I'm am going to do some powershell operations concurrently. I create powershell runspace every time and run certain commands. Let's say the first 5 commands are same for all operations. If I could run those commands only once for all operations and send a copy of the runspace to the multi threading method, it would be more efficient.
Means, I run some commands through a pipeline first.
Runspace runspace = RunspaceFactory.CreateRunspace()
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript("$var = 5"); //those 5 initial commands
pipeline.Invoke();
Now, I want to run certain commands concurrently.
Parallel.For(0, 5, new ParallelOptions { }, i => concurrentOperations(runspace, i));
The concurrentOperations method has been defined as this
private static void concurrentOperations(Runspace runspace, int i)
{
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript("$newVar = $var + " + i + "; $newVar"); //newer commands which differs for each operation
runspace.Open();
System.Collections.ObjectModel.Collection<PSObject> result = pipeline.Invoke();
foreach (PSObject obj in result)
{
Console.WriteLine("obj" + i + " : " + obj);
}
}
And now I encounter an exception that, "Pipelines cannot be run concurrently".
So, If I could make a copy of the runspace, the pipelines will be created for different runspaces only. But runspace doesnot have Clone() method in it.
Is there any way that I could achive this?
Need your help in solving this following issue.
We have a powershell script like:
invoke-command -ScriptBlock { [cmdletbinding()]
param(
[parameter(mandatory=$True)]
[string] $ticktfilepath
)
$ticketdetails=get-content $ticktfilepath |%{if ( $_ -like '"AB*' ) {$_}}|%{echo "$($_.Split(',')[7].Split('"')[1])=$($_.Split(',')[3].Split(':')[0].Split(' ')[$_.Split(',')[3].Split(':')[0].Split(' ').length-1])=$($_.Split(',')[0].Split('"')[1]);"}
write-output $ticketdetails } -ArgumentList 'D:\file.csv'
This script reads a csv file and for those lines in the csv with “AB…” at the start, does some string parsing. The csv file passed has rows with the “AB…” and hence result are returned. This runs perfectly when executing through powershell console or ISE.
But as per our requirement, where we trying to execute the same script through:
1. System.Diagnostics.Process with process start info having file name as powershell.exe and the argument at the above script. It fails for –like. i.e at |%{if ( $_ -like '"AB*' ). It is always false for the condition even though it is expected to be true.
N.B. other powershell script works perfectly with this approach
2. Exactly Similar issue when executed through System.Management.Automation.Runspaces
So looks like some constraint using the “–like” operator.
We even with the System.Diagnostics.Process approach tried writing the script line by line leveraging the Process.StandardInput.WriteLine(line) but then powershell hangs.
Any pointer to address this will be highly appreciated.
While using System.Diagnostics.Process, I used something like:
ProcessStartInfo processStartInfo = new ProcessStartInfo();
processStartInfo.UseShellExecute = false;
processStartInfo.RedirectStandardError = true;
processStartInfo.RedirectStandardOutput = true;
processStartInfo.FileName = "powershell.exe";
processStartInfo.Arguments = <ScriptContent>;
Process powerShellProc = new Process();
powerShellProc.StartInfo = processStartInfo;
powerShellProc.Start();
string successMessage = powerShellProc.StandardOutput.ReadToEndAsync().Result;
string errorMessage = powerShellProc.StandardError.ReadToEndAsync().Result;
powerShellProc.WaitForExit();
where,
ScriptContent- is the above powershell script.
Instead of like, even tried with startswith but then also the same result. But with powershell console or iSE, it works perfectly.
It's probably too late to answer :)
You shouldn't call powerShellProc.StandardOutput.ReadToEndAsync().Result before process actually finished. You can use Invoke-Executable function from How to capture process output asynchronously in powershell?
The following order is working
$outTask = $oProcess.StandardOutput.ReadToEndAsync();
$errTask = $oProcess.StandardError.ReadToEndAsync();
$bRet=$oProcess.WaitForExit($TimeoutMilliseconds)
$outText = $outTask.Result;
$errText = $errTask.Result;
I am trying to run following powershell cmdlet on my azurewebsite
public string RunPowerShellScript()
{
try
{
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open();
RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
Pipeline pipeline = runspace.CreatePipeline();
//Here's how you add a new script with arguments
Command myCommand = new Command("Set-AzureWebsite");
myCommand.Parameters.Add("Name", "rmssimple");
myCommand.Parameters.Add("HostNames ", "#('test.posxyz.com', 'xyz.com')");
pipeline.Commands.Add(myCommand);
var results = pipeline.Invoke();
return Content(results[0].ToString());
}
catch (Exception ex)
{
return Content(ex.Message);
}
}
but i get bellow error
The term 'Set-AzureWebsite' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
firts question : why do you wan tto do it like that? second, if you want to do it , you need to import the module first and the Powershell tools need to be installed. Importing the module is as follwos in PoSh : import-module Azure
I am executing builds using powershell script. I need to pass the process parameters run time based on the commandline arguments passed to the script. I am using TFS 2010.
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.Client")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.Build.Client")
$projectName = "test"
$buildName = "test.Build"
$tfsServer="xxx"
$tfsInstance = [Microsoft.TeamFoundation.Client.TeamFoundationServerFactory]::GetServer($tfsServer)
$buildService = $tfs.GetService([Microsoft.TeamFoundation.Build.Client.IBuildServer])
$buildDefinations = $buildService.QueryBuildDefinitions($projName)
Loop through all the builds to find the one we are looking for
foreach ($build in $buildDefinations)
{
Get the name of this build instance
$bNameInstance = $build.Name
$ClientName = "test1" #default set in the builddefination is "/p:xxx=test"
#Get the process parameters. I need to update the default value. How can we process the dictionary and update the value
$bMSBuildArguments = $build.ProcessParameters
#Once setting is done."/p:xxx=test1"
$build.ProcessParameters = $bMSBuildArguments
[Void]$buildService.QueueBuild($build)
}
I need help in updating the processparameters using the powershell code. I came across the C# (http://blogs.msdn.com/b/jpricket/archive/2010/03/25/tfs2010-queuing-a-build-from-code-with-custom-process-parameter-values.aspx)solution but not able convert that to Powershell
The answer is in the blog post provided. Try something like this:
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.Build.Workflow")
$request = $build.CreateBuildRequest()
$process = [Microsoft.TeamFoundation.Build.Workflow.WorkflowHelpers]::DeserializeProcessParameters($build.ProcessParameters)
#make changes to your process parameters in $process
$process.Item("asdf") = "new value"
$request.ProcessParameters = [Microsoft.TeamFoundation.Build.Workflow.WorkflowHelpers]::SerializeProcessParameters($process)
$buildService.QueueBuild($request)
