我想知道如何在CLR查找PDB符号文件，如果这种行为可以被覆盖。

I would like to know how the CLR locates pdb symbol files, and if this behavior can be overridden.

我在网上看了（MSDN和其他资源），也没有找到一个很好的答案。

I looked online (MSDN and other resources) but could not find a good answer.

在我的应用程序，我有放置在主.EXE路径的几个子目录的DLL。

In my app, i have DLLs placed in several subdirectories of the main .EXE path.

我想有一个符号\目录将包含我的应用程序的所有符号。 默认情况下，我认为，符号是从哪里组装回升。可以这样改？

I would like to have a Symbols\ dir that will contain all symbols for my application. By default, i believe that symbols are picked up from where the assembly is. Can this be changed?

您可以简单地设置_NT_SYMBOL_PATH环境变量为自己的过程。这种行之有效：

You could simply set the _NT_SYMBOL_PATH environment variable for your own process. This worked well:

using System;
using System.Runtime.CompilerServices;
using System.Reflection;
using System.IO;

class Program {
    static void Main(string[] args) {
        var path = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
        path = Path.Combine(path, "symbols");
        Environment.SetEnvironmentVariable("_NT_SYMBOL_PATH", path);
        try {
            Kaboom();
        }
        catch (Exception ex) {
            Console.WriteLine(ex.ToString());
        }
        Console.ReadLine();
    }
    [MethodImpl(MethodImplOptions.NoInlining)]
    static void Kaboom() {
        throw new Exception("test");
    }
}
