Re: invoke a method by reflection#,the method's parameters can not be ArrayList?

Here is your problem, the Invoke method overload you're using takes the target object and an array or arguments. In your case you only have one argument which is a object array.

Change:
object temp = myType.GetMethod("Exec").Invoke(myInstance, obj);

To:
object temp = myType.GetMethod("Exec").Invoke(myInstance,new object[]{ obj});
