c#读取进程列表判断程序是否已经启动（转）

方法一：using System.Diagnostics; Process[] vProcesses = Process.GetProcesses(); foreach (Process vProcess in vProcesses) if (vProcess.ProcessName.Equals( "iexplore ", StringComparison.OrdinalIgnoreCase)) { MessageBox.Show( "IE已经打开 "); break; }方法二：using System.Diagnostics;Process[] app = Process.GetProcessesByName("AMS");            if (app.Length > 0)            {                MessageBox.Show("请关闭已经启动的程序后再进行尝试");                return;            }            else            {                System.Diagnostics.Process.Start("AMS.exe");            }杀死进程：查找到对应的进程后就可以调用系统命令杀死指定名称的进程            Process[] p = Process.GetProcessesByName("AMS");            foreach (Process ps in p)            {                ps.Kill();            }
