Please comment: a book about using ExecuteReader () method to create a SqlDataReader object, object instantiation of a class, isn't it? Method is not only call? How to use methods to create objects? .

CodePudding user response:

Method is to have a return value, the return value can be a number, a string, or to create a good object,

CodePudding user response:
