Screen sharing with powershell - powershell

Question

i am trying to make a screen viewer.
i have an C# server side that works good and i have C# client side that works good.
this is my C# client side code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Net.Sockets;
using System.Net;
using System.Threading;
using System.Drawing.Imaging;
using System.Runtime.Serialization.Formatters.Binary;
namespace WindowsFormsApp24
{
public partial class Form1 : Form
{
private readonly TcpClient client = new TcpClient();
private NetworkStream mainStream;
private int portNumber;
private static Image GrabDesktop()
{
Rectangle bound = Screen.PrimaryScreen.Bounds;
Bitmap screenshot = new Bitmap(bound.Width, bound.Height, PixelFormat.Format32bppArgb);
Graphics graphics = Graphics.FromImage(screenshot);
graphics.CopyFromScreen(bound.X, bound.Y, 0, 0, bound.Size, CopyPixelOperation.SourceCopy);
return screenshot;
}
private void SendDesktopImage()
{
BinaryFormatter binFormatter = new BinaryFormatter();
mainStream = client.GetStream();
binFormatter.Serialize(mainStream, GrabDesktop());
}
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
portNumber = 443;
try
{
string ip = "192.168.1.55";
client.Connect(ip, portNumber);
}
catch
{
}
timer1.Start();
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
private void btnConnect_Click(object sender, EventArgs e)
{
}
private void timer1_Tick(object sender, EventArgs e)
{
SendDesktopImage();
}
}
}
The thing i am trying to do, is to switch the client side from C# to powershell.
is that possible? i am searching for ideas on google for along time, I would be happy
to hear what you have to say.. many thanks.

C# and Powershell are both using some version of the Dot Net runtime so the same objects and properties should be available in both, just by a different syntax. The process for converting between the two is basically this:
First you need to load the required assemblies into powershell with Add-Type. You will require several assemblies such as System.Net, System.Drawing and System.Windows.Forms to get access to the Objects in your code. (this is essentially the same as adding references to a C# project). Example: Add-Type -AssemblyName System.Drawing; would load everything inside System.Drawing.dll
Next you need to convert the syntax from C# to powershell line by line:
Example
private readonly TcpClient client = new TcpClient();
Would become:
[System.Net.Sockets.TcpClient] $client = New-Object System.Net.Sockets.TcpClient
Mostly this process will be simplification and expanding names. Above [System.Net.Sockets.TcpClient] is the fully qualified type - ie the long form name of the C# Class (visible on the tooltips in Visual Studio). New-Object is equivalent to new
Assuming you just want the screenshot to be taken and sent each time the script is executed you dont need to worry about writing classes or functions in powershell you can just convert each functional line of c# into powershell in a text file saved with .ps1 extension.
