动态调用DLL时不能加载依赖的程序集

假设有2个DLL, Class1和Class2. Class1引用Class2， 并调用Class2里的方法。

Code
AppDomain currentDomain = AppDomain.CurrentDomain;
currentDomain.AssemblyResolve += new ResolveEventHandler(MyResolveEventHandler);

static Assembly MyResolveEventHandler(object sender, ResolveEventArgs args)
{
string strFielName = args.Name.Split(',')[0];
return Assembly.LoadFile(string.Format( @"C:\test\{0}.dll",strFielName));
}
