QQDownload关机后关闭系统代码

     QQDownload 其自身带有“完成后关机”的功能，然而 完成下载后，只是关掉自身的进程，实现关闭程序，并未关机。完成后系统却还开着，浪费电。

如何实现其自动关机，小虾自己做了一个程序，解决了这个问题。

整体思路是这样：

1，启动关机 程序；

2，检测QQDownload是否运行；

3，完成后关机。

下面附出实现代码，可能比较冗余，请大家见谅。

    {

        {
            Process[] Curprocess = Process.GetProcesses();
            List<string> pList = new List<string>();//定义一个List
            foreach (Process p in Curprocess)
            {
                pList.Add(p.ProcessName.ToString());
            }
            return pList;
        }

            string[] pList = new string[Curprocess.Length];
            for (int i = 0; i < Curprocess.Length; i++)
            {
                pList[i] = Curprocess[i].ProcessName;
            }
            return pList;
