So far, many programming languages and tools contain support for regular expressions, and C # is no exception, and the C # base Class library contains a namespace (System.Text.RegularExpressions) and a series of classes that can give full play to

In general, a class will have multiple constructors. Over time, member variables and constructors are increasing. The easiest way to handle this situation is to initialize the variable when declaring it instead of in each constructor. Whether a

In the process of project development using object-oriented language, more "inheritance" features are used, but not all scenarios are suitable for the use of "inheritance" features, and some of the basic principles of design patterns are also
