C# – Run Application

These are two ways to use the Process class to launch an EXE. Both were tested in Visual Studio 2017.

Simplest usage—just launch an EXE.

using System.Diagnostics;

class Program
{
static void Main()
{
// Add your app name here
Process.Start(@"C:\Windows\system32\notepad.exe");
}
}

 

Intermediate usage—launch an EXE with credentials using SecureString

using System.Diagnostics;
using System.Security;

class Program
{
static void Main(string[] args)
{

SecureString strPassword = new SecureString();
// password by character
// it is important to use AppendChar
strPassword.AppendChar('P');
strPassword.AppendChar('a');
strPassword.AppendChar('s');
strPassword.AppendChar('s');
strPassword.AppendChar('w');
strPassword.AppendChar('o');
strPassword.AppendChar('r');
strPassword.AppendChar('d');

Process objProcess = new Process();
objProcess.StartInfo.LoadUserProfile = false;
objProcess.StartInfo.UseShellExecute = false;
objProcess.StartInfo.CreateNoWindow = false;

// enter the app path here
objProcess.StartInfo.WorkingDirectory = @"C:\Windows\system32";

// enter the app name here
objProcess.StartInfo.FileName = "notepad.exe";

// domain name
objProcess.StartInfo.Domain = ".";

// user account
objProcess.StartInfo.UserName = "administrator";
objProcess.StartInfo.Password = strPassword;
objProcess.Start();

}
}
