如何在c#中终止外壳程序执行的进程

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
        // 进程名称，例如 "cmd.exe" 或 "powershell.exe"
        string processName = "cmd.exe";

        // 获取所有匹配的进程
        Process[] processes = Process.GetProcessesByName(processName);

        foreach (Process process in processes)
        {
            try
            {
                // 终止进程
                process.Kill();
                Console.WriteLine($"进程 {process.ProcessName} 已终止。");
            }
            catch (Exception ex)
            {
                Console.WriteLine($"无法终止进程 {process.ProcessName}，错误信息: {ex.Message}");
            }
        }
    }
}
