判断本地计算机是否启动指定进程

string vProcessName = "QQ";//定义要查寻的进程名称

Process[] vProcess = Process.GetProcesses();

bool vIsRuning = false;//记录进程是否已经启动 默认为false

try

{

foreach (Process pProcess in vProcess)

{

//在这里将进程统一转换为小写以便正确判断

if (pProcess.ProcessName.ToLower().Trim().Equals(vProcessName.ToLower().Trim()))

{

vIsRuning = true;

break;

}

}

if (vIsRuning)

{

MessageBox.Show(vProcessName + " 进程已经启动");

}

else

{

MessageBox.Show(vProcessName + " 进程没有启动");

}

}

catch (Exception ex)

{

MessageBox.Show("查询过程发生错误，错误信息：" + ex.Message);

}
