暂停线程，直到其他程序/进程完成运行 [英] Pausing thread until other program/process finishes to run

问题描述

大家好，

我正在尝试在映射网络驱动器时暂停我的主线程，但每次网络驱动器映射的时间都不同。我不想使用Thread.Sleep（< static number =>）。

该程序如下：

线程T2 =  new 线程（（）= >  
 {
 System.Diagnostics.Process.Start（  net.exe， @ 使用Z：\\Server-Share \My_Files \）; 
} 
 T2.Start（）; 
 T2.Join（）; 
 File.Copy（ @  C：\daily_files\Updated_data.xlsx， @  Z：\ Updated_data.xlsx ， true ）; 

这里的问题是T2启动网络驱动器的映射，这需要3-5秒，主线程的下一步是复制粘贴文件到新的共享。复制粘贴开始时间早于网络共享映射完成 - 然后我得到错误，该位置不可用...所以 - 看起来网络共享映射正在其自己的线程中运行....

有谁知道如何使主线程等待共享驱动器映射完成？



非常感谢大家！

解决方案

创建一个实例 System.Diagnostics.Process 而是设置 StartInfo 属性并在上注册一个处理程序在调用开始之前退出。然后在进程退出时触发退出的事件，至少我的阅读方式是 this [ ^ ];）

Hello guys,
I''ve been trying to pause my main thread while the network drive is being mapped, but each time the time for network drive mapping is different. I don''t want to use Thread.Sleep(<static number="">).
The program is as follows:

Thread T2 = new Thread(() =>
{
System.Diagnostics.Process.Start("net.exe", @"use Z: \\Server-Share\My_Files\");
}
T2.Start();
T2.Join();
File.Copy(@"C:\daily_files\Updated_data.xlsx", @"Z:\Updated_data.xlsx", true);

The problem here is that T2 starts the mapping of network drive, which takes 3-5 seconds and the next step in main thread is copy-paste file to that new share. And the copy-paste starts earlier then the network share mapping finishes - then I get error that location is not available... So - looks like the network share mapping is running in its own thread....
Does anyone know how to make main thread wait for the shared drive mapping to finish?

Thanks a lot guys!

解决方案

Create an instance of System.Diagnostics.Process instead, set the StartInfo property and register a handler on Exited before calling Start. The Exited event is then fired when the process exits, at least that''s how I read this[^] ;)
