To run a PowerShell script from a C# Windows Forms Application, you can use the System.Management.Automation class to execute PowerShell.exe and pass the argument.

Open your Visual Studio, then create a new Windows Forms Application project.

Next, Drag and drop the TextBox, Button and Label controls from the Visual studio toolbox to your winform.

c# winform powershell

To play the demo, you need to install the System.Management.Automation from the Manage Nuget Packages to your project.

The System.Management.Automation library helps you run powershell in c# winform.

Next, Create the RunScript method allows you to run the command. You can input get-process, get-service...etc, then write c# run powershell command and get output as shown below.

private string RunScript(string script)
    Runspace runspace = RunspaceFactory.CreateRunspace();
    Pipeline pipeline = runspace.CreatePipeline();
    Collection<PSObject> results = pipeline.Invoke();
    StringBuilder stringBuilder = new StringBuilder();
    foreach (PSObject ps in results)
    return stringBuilder.ToString();

You can use c# powershell runspace to run powershell script from c# with parameters.

Adding click event handler to the Run button allows you to run powershell script from c# windows form.

private void btnRun_Click(object sender, EventArgs e)
    txtResult.Text = RunScript(txtComand.Text);

You can also use the System.Diagnostics.Process class to execute PowerShell.exe and pass the script file as an argument.

private void btnRun_Click(object sender, EventArgs e)
    string scriptPath = @"C:\Script.ps1"; // Path to your PowerShell script
    // Create a process start info
    ProcessStartInfo psi = new ProcessStartInfo
        FileName = "powershell.exe",
        Arguments = $"-ExecutionPolicy Bypass -File \"{scriptPath}\"",
        RedirectStandardOutput = true,
        RedirectStandardError = true,
        UseShellExecute = false,
        CreateNoWindow = true

    // Create the process
    Process process = new Process
        StartInfo = psi

    // Start the process

    // Read the output and errors if needed
    string output = process.StandardOutput.ReadToEnd();
    string error = process.StandardError.ReadToEnd();

    // Wait for the process to exit

In this example when the user clicks a button, it executes the PowerShell script.

The PowerShell script runs with the -ExecutionPolicy Bypass argument to bypass the PowerShell script execution policy, and -File to specify the script file to execute.
