How to wait until remote .NET debugger attached
提问by Clinton Pierce
Today I ran into a problem were I needed to remote-debug a program. The program was launched from another system, so I really don't have an opportunity to interact with it on the command line. I could change its source easily though.
今天我遇到了一个问题，我需要远程调试一个程序。该程序是从另一个系统启动的，所以我真的没有机会在命令行上与它进行交互。不过，我可以轻松更改其来源。
What I needed to happen was for the program to start normally, and then wait for me to attach to it with a debugger. I couldn't come up with a way to do it that made me happy. I did find the bug, but without the help of the debugger.
我需要做的是让程序正常启动，然后等待我用调试器附加到它。我想不出让我开心的方法。我确实找到了错误，但没有调试器的帮助。
while(true) { }
Kept the process alive, and then I could "set next statement" with the debugger, but it seemed awkward and rude.
保持进程活跃，然后我可以用调试器“设置下一个语句”，但这看起来很尴尬和粗鲁。
Console.ReadLine();
Seemed odd to type since there wasn't actually a Console for me to press enterat. (It didn't work, either. Set next statement and then run takes you back into the ReadLine() wait.)
输入似乎很奇怪，因为实际上没有控制台供我按Enter键。（它也不起作用。设置下一条语句，然后运行将带您回到 ReadLine() 等待。）
So what kind of code can I insert into a .NET/CLR/C# program that says "wait here until I can attach with a debugger"?
那么，我可以在 .NET/CLR/C# 程序中插入什么类型的代码，该程序说“请等待，直到我可以附加调试器”？

You can use the System.Diagnostics.Debugger.IsAttachedproperty to check if a debugger is attached to the process. This application will wait until a debugger has been attached:
您可以使用System.Diagnostics.Debugger.IsAttached属性来检查调试器是否附加到进程。此应用程序将等待调试器已附加：
using System;
using System.Diagnostics;
using System.Threading;
namespace DebugApp
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Waiting for debugger to attach");
while (!Debugger.IsAttached)
{
Thread.Sleep(100);
}
Console.WriteLine("Debugger attached");
}
}

This sounds like exactly what you need:
这听起来正是您所需要的：
Debugger.Launch();
http://msdn.microsoft.com/en-us/library/system.diagnostics.debugger.launch.aspx
http://msdn.microsoft.com/en-us/library/system.diagnostics.debugger.launch.aspx
"Launches and attaches a debugger to the process."
“启动并将调试器附加到进程中。”

I don't know, since I've never tried it but I wonder if you could use System.Diagnostics.Debugger.Break()in order to have it hit a breakpoint and then wait for a debugger to attach. I assume a remote debugger would work, but I do not know for sure and currently do not have access to my home environment where I could easily mock it up and test my theory. There's an MSDN articletalking about using it in an ASP.Net application so I imagine it would work.
我不知道，因为我从未尝试过，但我想知道您是否可以使用System.Diagnostics.Debugger.Break()它来让它达到断点，然后等待调试器附加。我假设远程调试器可以工作，但我不确定，目前无法访问我的家庭环境，我可以轻松地模拟它并测试我的理论。有一篇MSDN 文章谈到在 ASP.Net 应用程序中使用它，所以我想它会起作用。

Attaching remote debugger works exactly the same as using local debugger.
附加远程调试器的工作方式与使用本地调试器完全相同。
First, do the usual:
首先，做通常的：
System.Diagnostics.Debugger.Launch();
You will see a prompt to chose debugger. At this point the execution is suspended, so so you can attach remote debugger and select "No" from the prompt.
您将看到选择调试器的提示。此时执行已暂停，因此您可以附加远程调试器并从提示中选择“否”。

Debug.Assert(true);
should also work I guess. By the way, I also face this proble at times and I do
我猜也应该工作。顺便说一句，我有时也面临这个问题，我确实
MessageBox.Show()
:P :P

Set a timeout that gives you time to attach the debugger.
设置一个超时时间，让您有时间连接调试器。
Thread.Sleep(30000);
