Best way to run external program

Sometime you might look the way to run external program from your C# application.
If so, you should interest Process.Start() method inside using System.Diagnostics namespace.

Below I'm presenting code snippets doing common task for us:

<br />// Example 1<br />//<br />// run external process and wait<br />Process proc = Process.Start("notepad.exe");<br />while (!proc.HasExited) {<br /> System.Windows.Forms.Application.DoEvents();<br />}<br /><br />// Example 2<br />//<br />// open C:\ folder in explorer<br />Process.Start("C:\\");<br /><br />// Example 3<br />//<br />// External program call wit parameters<br />// For the example<br />string dir1 = "C:\\Dir\\Temp";<br /><br />// Use ProcessStartInfo class<br />ProcessStartInfo startInfo = new rocessStartInfo();<br />startInfo.CreateNoWindow = false;<br />startInfo.UseShellExecute = false;<br />startInfo.FileName = "extApp.exe";<br />startInfo.WindowStyle = ProcessWindowStyle.Hidden;<br />startInfo.Arguments = " --input_dir \"" + dir1 + "\";<br /><br />// run process and release resources after finish (thanks to using statement)<br />try {<br /> using (Process exeProcess = Process.Start(startInfo)) {<br /> exeProcess.WaitForExit();<br /> }<br />}<br />catch {<br /> // Error here<br />}<br />
