C＃ - 制作的Process.Start等到进程启动 [英] C# - Making a Process.Start wait until the process has start-up

问题描述

我需要确保一个进程正在与一个方法之前运行。

I need to make sure that a process is running before moving on with a method.

的说法是：

Process.Start("popup.exe");

您可以做一个等待命令或设置这个值的延迟？

Can you do a WAIT command or set a delay on this value?

推荐答案

你的意思是等待，直到它完成？然后使用 Process.WaitForExit ：

Do you mean wait until it's done? Then use Process.WaitForExit:

var process = new Process {
    StartInfo = new ProcessStartInfo {
        FileName = "popup.exe"
    }
};
process.Start();
process.WaitForExit();

另外，如果是与正在等待进入一个消息循环的UI的应用程序，你可以说：

Alternatively, if it's an application with a UI that you are waiting to enter into a message loop, you can say:

process.Start();
process.WaitForInputIdle();

最后，如果没有这些应用，只需 Thread.sleep代码一段合理的时间内：

Lastly, if neither of these apply, just Thread.Sleep for some reasonable amount of time:

process.Start();
Thread.Sleep(1000); // sleep for one second
