有关AppDomain.Load方法

[antoniusguo]

System.AppDomainSetup setup = new AppDomainSetup();
setup.ApplicationBase = @"C:\MyAssemblies\";
setup.PrivateBinPath = System.AppDomain.CurrentDomain.BaseDirectory;
System.AppDomain domain = System.AppDomain.CreateDomain("MyDomian", null, setup);
domain.Load("Test.MyDll");

文件路径是
C:\MyAssemblies\MyDll.dll
类名为
Test.MyDll
运行到
domain.Load("Test.MyDll");
这里到这里抛出
System.IO.FileNotFoundException
具体这个怎么使用不是很清楚，以前用的是Assembly.LoadFile方法
