using System.Diagnostics;
class Program
{
static void Main()
{
Process.Start("C:\\");
}
}
If your application needs cmd arguments, use something like this:
using System.Diagnostics;
class Program
{
static void Main()
{
LaunchCommandLineApp();
}
/// <summary>
/// Launch the application with some options set.
/// </summary>
static void LaunchCommandLineApp()
{
// For the example
const string ex1 = "C:\\";
const string ex2 = "C:\\Dir";
// Use ProcessStartInfo class
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.CreateNoWindow = false;
startInfo.UseShellExecute = false;
startInfo.FileName = "dcm2jpg.exe";
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;
try
{
// Start the process with the info we specified.
// Call WaitForExit and then the using statement will close.
using (Process exeProcess = Process.Start(startInfo))
{
exeProcess.WaitForExit();
}
}
catch
{
// Log error.
}
}
}

startInfo.UseShellExecute = false was an awesome thing...It worked for me like a charm! Thank you! :)

@logganB.lehman process hangs forever on exeProcess.WaitForExit(); any idea?
Example:
System.Diagnostics.Process.Start("mspaint.exe");
Compiling the Code
Copy the code and paste it into the Main method of a console application. Replace "mspaint.exe" with the path to the application you want to run.

How does this provide more value than the already created answers? The accepted answer also shows the usage of
Process.Start()

SO - it's OK to help a beginner with simplified, step by step examples with many details stripped away. Also ok to use caps :P

I just needed a quick way to execute the exe and this was really helpful. Thank you :)
Look at Process.Start and Process.StartInfo

Can you make your answer more comprehensive? And/or point to a duplicate?
Example:
Process process = Process.Start(@"Data\myApp.exe")
int id = process.Id
Process tempProc = Process.GetProcessById(id)
this.Visible = false
tempProc.WaitForExit()
this.Visible = true

You can create 2 executables: one is your main application and the other is an exe that will call your main application. The other exe will also be the one to update your main application.
