Windows Forms: How to run Script Windows Power Shell in C#

Creating a new Windows Froms Application project, then drag TextBox, Button and Label controls from the visual studio toolbox to your winform.

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();
    runspace.Open();
    Pipeline pipeline = runspace.CreatePipeline();
    pipeline.Commands.AddScript(script);
    pipeline.Commands.Add("Out-String");
    Collection<PSObject> results = pipeline.Invoke();
    runspace.Close();
    StringBuilder stringBuilder = new StringBuilder();
    foreach (PSObject ps in results)
        stringBuilder.AppendLine(ps.ToString());
    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.Clear();
    txtResult.Text = RunScript(txtComand.Text);
}
