How Can I Shut Down a Windows Computer Using C#?

C# Simple method to shut down the computer gracefully

Want to easily shut down your computer in a C# program? Although there are many methods, not many can combine simplicity and native .NET functionality.

For Windows XP and above, there is a simple solution:

<code class="language-csharp">Process.Start("shutdown","/s /t 0");</code>

This command will shut down the computer immediately without any delay.

If you need compatibility with Windows 2000 or earlier, you need to use P/Invoke or WMI. However, if you want a more flexible approach, consider the following code:

<code class="language-csharp">var psi = new ProcessStartInfo("shutdown","/s /t 0");
psi.CreateNoWindow = true;
psi.UseShellExecute = false;
Process.Start(psi);</code>

This code avoids ugly windows during shutdown and ensures a smooth experience.
