如何等到远程.NET调试器附加

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。我可以轻松改变它的来源。

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连接它。我无法想出办法让我开心。我找到了错误，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.

保持进程活着，然后我可以用调试器“设置下一个语句”，但它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 enter at. (It didn't work, either. Set next statement and then run takes you back into the ReadLine() wait.)

看起来很奇怪，因为实际上没有一个控制台供我输入。（它也没有用。设置下一个语句然后运行会带你回到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＃程序中插入什么样的代码来说“在这里等到我可以附加调试器”？

You can use the System.Diagnostics.Debugger.IsAttached property 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。此应用程序将等待直到附加调试器：

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:

这听起来就像你需要的：

Debugger.Launch();

http://msdn.microsoft.com/en-us/library/system.diagnostics.debugger.launch.aspx

"Launches and attaches a debugger to the process."

“启动并附加调试程序。”

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 article talking about using it in an ASP.Net application so I imagine it would work.

我不知道，因为我从来没有尝试过，但我想知道你是否可以使用System.Diagnostics.Debugger.Break（）以使其达到断点然后等待调试器附加。我假设一个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文章讨论在ASP.Net应用程序中使用它，所以我想它会起作用。

#4

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。顺便说一下，我有时也会遇到这个问题

MessageBox.Show()

:P :P

：P：P

#5

Set a timeout that gives you time to attach the debugger.

设置超时，为您提供连接调试器的时间。

Thread.Sleep(30000);

#6

Attaching remote debugger works exactly the same as using local debugger.

附加远程调试器与使用本地调试器完全相同。

First, do the usual:

首先，做通常的事情：

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。此时执行被暂停，因此您可以附加远程调试器并从提示中选择“否”。
