如何等到远程.NET调试器连接 [英] How to wait until remote .NET debugger attached

问题描述

今天遇到一个问题是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。我可以很容易地改变它的源。

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.

我需要发生的是程序正常启动，然后等待我使用调试器附加它。我无法想出一个让我开心的方法。我确实发现了错误，但没有调试器的帮助。

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.

while(true) { }

保留该进程，然后我可以使用调试器设置下一个语句，但它似乎很尴尬和粗鲁。 p>

Kept the process alive, and then I could "set next statement" with the debugger, but it seemed awkward and rude.

Console.ReadLine();

看起来很奇怪，因为实际上没有一个控制台可以按输入在。 （它没有工作，或者，设置下一个语句，然后运行会让你回到ReadLine（）等待。）

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.)

那么我可以插入什么样的代码一个.NET / CLR / C＃程序，说等待这里直到我可以附加一个调试器？

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"?

推荐答案

你可以使用 System.Diagnostics.Debugger.IsAttached 属性检查调试器是否附加到进程。此应用程序将等待直到调试器被附加：

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:

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");
        }
    }
}
