How do I call a program ? Create Button

[sentinelace]

I am trying to write a program to browse to a WSP file and then run the STSADM to make it easier to add solutions to our sharepoint site. The STSADMN is located in c:\program files\common files\microsoft shared\web server extensions\14\bin\stsadmn.exe.

So I need to point to this EXE and run this command:

stsadm -o addsolution -filename "filename that was selected"

This currently has to run in powershell.

After that completes I need it to run this:

stsadm -o deploysolution -name "selected WSP" -url http://sharepoint -allowgacdeployment -immediate

I am just not sure how to call powershell and then run this command. and of course a messagebox.show "Completed". All I have right now is a form that browses to a WSP

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            OpenFileDialog fDialog = new OpenFileDialog();
            fDialog.Title = "Open WSP File";
            fDialog.Filter = "WSP Files|*.wsp";
            fDialog.InitialDirectory = @"C:\";
            if(fDialog.ShowDialog() == DialogResult.OK) 
            {

            MessageBox.Show(fDialog.FileName.ToString());

            }




        }
    }
}

Any help appreciated while I'm a noob at C# but loving it!
