c#读取进程列表判断程序是否已经启动

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();

            }
