Type.GetType 获得本Assembly以外的类型

   简而言之，就是相应AppDomain.的AssemblyResolve实现的。
   DynAssembly提供给动态载入的模块提供一个解析名字的机会。如下代码可以把NHibernate 的Hbm.xml 生成 数据库结构。

using System;
using System.Collections.Generic;
using System.Text;
using NHibernate.Cfg;
using NHibernate.Tool.hbm2ddl;

namespace Hbm2Sql
{
    class DynAssembly
    {
        System.Reflection.Assembly _asm;

        public DynAssembly(System.Reflection.Assembly asm)
        {
            this._asm = asm;
            AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(this.TypeResolve);
        }

        public System.Reflection.Assembly TypeResolve(object sender, ResolveEventArgs args)
        {
            if (_asm.FullName.Contains(args.Name))
            {
                return _asm;
            }
            return null;
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                if (args.Length > 0)
                {
                    System.Console.Write("命令行:");
                    System.Console.WriteLine(string.Join(" ",args));

                    System.Reflection.Assembly asm = AppDomain.CurrentDomain.Load(System.Reflection.AssemblyName.GetAssemblyName(args[0]));
                    new DynAssembly(asm);
                    NHibernate.Cfg.Configuration cfg = new Configuration().Configure()
                                                        .AddAssembly(asm);
                    SchemaExport export = new SchemaExport(cfg);
                    export.Create(true, false);
                }
            }
            catch (System.Exception e)
            {
                System.Console.Write(e.ToString());
            }
            finally
            {
                System.ConsoleKeyInfo i = System.Console.ReadKey();
            }
        }
    }
}
