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

问题描述

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.不过，我可以轻松更改其来源.

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.

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) { }

让进程保持活动状态，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.

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

Console.ReadLine();

输入似乎很奇怪，因为实际上没有控制台供我按 enter 在.(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.)

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，我可以在 .NET/CLR/C# 程序中插入什么类型的代码，该程序显示在此等待，直到我可以使用调试器进行附加"?

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

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，直到附加了调试器:

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:

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");
        }
    }
}
