如何知道进程是否正在运行? [英] How can I know if a process is running?

问题描述

当我获得对 System.Diagnostics.Process 的引用时，我如何知道进程当前是否正在运行?

When I get a reference to a System.Diagnostics.Process, how can I know if a process is currently running?

推荐答案

这是一种用名字来做的方法:

This is a way to do it with the name:

Process[] pname = Process.GetProcessesByName("notepad");
if (pname.Length == 0)
  MessageBox.Show("nothing");
else
  MessageBox.Show("run");

您可以循环所有进程以获取 ID 以供以后操作:

You can loop all process to get the ID for later manipulation:

Process[] processlist = Process.GetProcesses();
foreach(Process theprocess in processlist){
   Console.WriteLine("Process: {0} ID: {1}", theprocess.ProcessName, theprocess.Id);
}
