How do I start a process from C#?

Question

How do I start a process, such as launching a URL when the user clicks a button?

Answer 1

class ProcessStart
{
    static void Main(string[] args)
    {
        Process notePad = new Process();

        notePad.StartInfo.FileName   = "notepad.exe";
        notePad.StartInfo.Arguments = "ProcessStart.cs";

        notePad.Start();
    }
}

Answer 2

I used the following in my own program.

Process.Start("http://www.google.com/etc/etc/test.txt")

It's a bit basic, but it does the job for me.

Answer 3

To start Microsoft Word for example, use this code:

private void button1_Click(object sender, EventArgs e)
{
    string ProgramName = "winword.exe";
    Process.Start(ProgramName);
}

Answer 4

Include the using System.Diagnostics;.

And then call this Process.Start("Paste your URL string here!");

Try something like this:

using System.Web.UI;
using System.Web.UI.WebControls;
using System.Diagnostics;

namespace btnproce
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            string t ="Balotelli";
            Process.Start("http://google.com/search?q=" + t);
        }
    }
}

Please note that it is a sample ASP.NET page as an example. You should try and improvise a little bit.

Answer 5

You can use the System.Diagnostics.Process.Start method to start a process. You can even pass a URL as a string and it'll kick off the default browser.

Answer 6

var path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "/YourSubDirectory/yourprogram.exe");
Process.Start(new ProcessStartInfo(path));
