获取对象时发生异常：无法从程序集中加载类型

Question

我正在使用SystemWrapper来简化IO工作。
这是我的代码

var diMock = new Mock<IDirectoryInfo>(); 
diMock.Setup(i => i.Create()).Throws(new Exception("num"));
try
{
      var obj = diMock.Object;
}catch(Exception ex)
{
   //Could not load type 'System.Runtime.Remoting.ObjRef' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
}

调用堆栈为：

有什么想法吗？
