How to use the C # identifier

This article introduces the knowledge of "how to use the C# identifier". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Usage in the C # identifier

In the C# specification, @ can be used as * * characters of C# identifiers (class names, variable names, method names, etc.) to allow keywords to be retained in C# as self-defined C# identifiers.

Class @ class {public static void @ static (bool @ bool) {if (@ bool) System.Console.WriteLine ("true"); else System.Console.WriteLine ("false");}} class Class1 {static void M () {cl\ u0061ss.st\ u0061tic (true);}}

Note that although @ appears in the C# identifier, it is not part of the C# identifier itself. Therefore, in the above example, a class named class is defined and contains a method named static and a formal parameter named bool. In this way, it is convenient for cross-language migration. Because a word is used as a reserved keyword in C#, but it may not be in other languages.
