RTTI is the abbreviation for "Runtime type Information", meaning: run-time type information. It provides a way to determine the object type at run time. This article will briefly introduce some background knowledge of RTTI, describe the concept of

In C #, it is often necessary to convert value types and reference types to each other.First clear two rules:1. The reference type is always assigned to the heap.2. The value type is always assigned to the place it declares:A. Assigning a member
