如何从动态生成的程序集中引用GAC程序集

我正在用C#自学中间语言(IL(生成，我一直在学习如何从动态程序集中引用System.Windows.Forms.dll(例如(，我正在使用AppDomain.CurrentDomain.DefineDynamicAssembly和System.Reflection.Emit生成。。。基于http://olondono.blogspot.com/2008/02/creating-code-at-runtime.html

我已经有了一个基本的TransferObjectDllGenerator，但现在我想引用(仅(生成的程序集中的现有库，但不知道如何引用。

这个SO问题引出了AppDomain.CurrentDomain.AssemblyResolve事件。我尝试实现一个事件处理程序，但它从未被触发，所以我想我做了一些基本上愚蠢的事情，比如把事件处理程序放在完全错误的地方？

任何指向正确方向的指针都将不胜感激。

这是我的主线。。。感兴趣的比特是// <<-- Commented thus

            });
            Console.WriteLine("Generated: " + dll.Save());
        } finally {
            AppDomain.CurrentDomain.AssemblyResolve -= MyAssemblyResolver; // <<-- Unhook the "resolve this assembly" event.
        }
    }
    static Assembly MyAssemblyResolver(object sender, ResolveEventArgs args) // <<-- Handle the "resolve this assembly" event.
    {
        if ( args.Name.StartsWith("System.Windows.Forms.") ) // <<-- Breakpoint here, which is never reached.
            return Assembly.LoadFrom(@"C:'Windows'winsxs'msil_system.windows.forms_b77a5c561934e089_6.0.6001.22230_none_1a2132e45d2f30fc'System.Windows.Forms.dll");

如果您需要/想要TransferObjectDllGenerator代码，请大喊。。。我没有发布它，因为它对于论坛帖子来说有点太大了。

提前感谢您抽出时间。

干杯。基思。

编辑：为将来找到此线程的任何人提供一个工作示例。

不需要提供自定义的AssemblyResolve事件处理程序。那是一个骗局。我们只需要提供程序集的完全限定名称。。。其中一个具有程序集名称、命名空间、版本和GUID。

using System;
using System.Reflection;
namespace ILGen
{
public class Program
{
    public static void Main(String[] args) {
        var dll = new TransferObjectDllGenerator("PersonLibrary"); 
        // We need to provide the fully-qualified-assembly-name to 
        // make the standard assembly-resolver search the GAC. 
        // Thanks to Julien Lebosquain for pointing this out.
        Type buttonType = Type.GetType(
            "System.Windows.Forms.Button, System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"); 
        dll.AddClass("Person", new[] {
            new Property("FirstName", typeof(string))
          , new Property("LastName", typeof(string))
          , new Property("OK", buttonType) 
        });
        Console.WriteLine("Generated: " + dll.Save());
    }
} // end-class
} // end-namespace
