MSDN System.Diagnostics.Process
If you want to know right now, you can check the HasExitedproperty.
如果你现在想知道，你可以检查HasExited财产。
var isRunning = !process.HasExited;
If it's a quick process, just wait for it.
如果这是一个快速的过程，只需等待。
process.WaitForExit();
If you're starting one up in the background, subscribe to the Exited event after setting EnableRaisingEvents to true.
如果您在后台启动，请在将 EnableRaisingEvents 设置为 true 后订阅 Exited 事件。
process.EnableRaisingEvents = true;
process.Exited += (sender, e) => { /* do whatever */ };

Be sure you save the Processobject if you use the static Process.Start()call (or create an instance with new), and then either check the HasExitedproperty, or subscribe to the Exitedevent, depending on your needs.
Process如果您使用静态Process.Start()调用（或使用 创建实例new），请确保保存对象，然后根据您的需要检查HasExited属性或订阅Exited事件。

Take a look at the MSDN documentation for the Process class.
In particular there is an event (Exited) you can listen to.
特别是有一个事件（Exited）您可以收听。

Process p = new Process();
p.Exited += new EventHandler(p_Exited);
p.StartInfo.FileName = @"path to file";
p.EnableRaisingEvents = true;
p.Start();
void p_Exited(object sender, EventArgs e)
{
MessageBox.Show("Process exited");
}
