turn off computer in csharp

In order to turn off the computer using C#, you can use the built-in Process class to execute the appropriate system command. Here's an example code snippet:

main.cs
using System.Diagnostics;

// ...

Process.Start("shutdown", "/s /t 0");
73 chars
6 lines

The /s flag tells the shutdown command to turn off the computer. The /t 0 flag specifies the delay in seconds before shutting down (in this case, 0 seconds, meaning immediate shut down.)

Note that this code requires administrative privileges to execute.
