Calling PowerShell Get-SPContentDatabase in C# - powershell

Question

I am trying to use the Get-SPContentDatabase powershell command from a code behind file:
using (PowerShell PowerShellInstance = PowerShell.Create())
{
PowerShellInstance.AddScript("Get-SPContentDatabase -site http:////gBox.contoso.com");
Collection<PSObject> PSOutput = PowerShellInstance.Invoke();
if (PSOutput.Count > 0)
{
foreach (PSObject outputItem in PSOutput)
{
if (outputItem != null)
{
lblResults.Text += outputItem.BaseObject.ToString();
lblResults.Text += outputItem.BaseObject.GetType().FullName;
lblResults.Text += "<hr>";
}
}
}
else
{
lblResults.Text = "No output found";
}
}
However, the PSOutput keeps coming back with zero objects.
The Command works great from the PowerShell window, but not from the code behind.
Any thoughts?

The command Get-SPContentDatabase is failed to execute since Microsoft.SharePoint.PowerShell module have to be loaded first:
using (var psInst = PowerShell.Create())
{
psInst.AddScript("Add-PsSnapin Microsoft.SharePoint.PowerShell");
}
Example: print ContentDb names
using (var psInst = PowerShell.Create())
{
psInst.AddScript("Add-PsSnapin Microsoft.SharePoint.PowerShell");
psInst.AddScript("Get-SPContentDatabase -site http://contoso.intranet.com/");
var result = psInst.Invoke();
foreach (var outputItem in result)
{
var contentDb = outputItem.BaseObject as SPContentDatabase;
Console.WriteLine(contentDb.Name);
}
}
