The foundation is the heavy ~emit dynamic construction method (parameters and return values)

For emit we know that it can dynamically build assemblies, types, methods, properties, etc., or you can create them dynamically using emit, as long as they are created using C #, emit because of its special place, so it has been widely used in many fields, like the recent comparison of Fire AOP technology, Its most core function is the method interception, we use emit also can implement method interception function, detailed can see uncle this article "Lind.DDD.Aspects through plugins realization method dynamic interception ~lind AOP".

Methods that have parameters and no return values are constructed and called
