c# – 订阅已加载程序集的事件

以下是加载Dll文件的代码的一部分：

Assembly asm = Assembly.LoadFile(@"C:ProjectsDll1.Dll");
Type typ = asm.GetType("DLL1.Class1",true,true);

var method = typ.GetMethod("add");
var obj = Activator.CreateInstance(typ);

EventInfo ev1 = typ.GetEvents()[0]; // just to check if I have the proper event
Type tDelegate = ev1.EventHandlerType; // just to check if I have the proper delegate

method.Invoke(obj,new object[] { 1,0 });

但是,我不知道如何订阅程序集引发的事件.任何帮助,将不胜感激.

补充：示例DLL源

namespace Dll1
{
    public class Class1
    {
        int c = 0;

        public void add(int a,int b)
        {
            c =  a + b;
            if (Added !=null)
                Added(this,new AddArgs(c));
        }

        public delegate void AddHandler(object sender,AddArgs e);

        public event AddHandler Added;

    }

    public class AddArgs : EventArgs
    {
        private int intResult;

        public AddArgs(int _Value) 
        {
            intResult = _Value;
        }

        public int Result
        {
            get { return intResult; }
        }
    }
}
