In practice, we need to write a large number of programs, for example, to convert a table into a class object or write a method to call a stored procedure with N parameters, You need to manually enter a large amount of code, and there is a lot of

C # differences between reference types and value types We all know that the two data types of C # Are value type and reference type respectively. Many people may be able to tell with closed eyes that the value types include simple type, struct

A class is used to display a GUI menu with a background pattern. This class is used in a multi-threaded environment: Class prettymenu {Public:...Void changebackground (STD: istream & imgsrc );...PRIVATE:Mutex;Image * bgimage;Int
