【 求助】要用哪个命令来关闭

string name = "QQ.exe";//程序进程名称
            string han = "TX_SSO_SHARE_INFO_0";  //句柄名称
            Process[] prc = Process.GetProcesses();
            foreach (Process pr in prc)//遍历整个进程
            {

               
              if (name == pr.ProcessName)//如果进程存在
                {
                    IntPtr Handle = pr.Handle;//获取进程的句柄                 
                }                          
            }
接下去要关闭han这个句柄，是不是要先遍历获取的句柄，求解遍历Handle里的句柄是用foreach吗？
