Csharp identifiers

C# Identifiers


Identifiers are the names given to various elements of the programs like variables, classes, namespaces, interfaces and structures.
Here are some rules which are defined for the C# Identifiers given below:


  • Identifier can use the alphabets, digits and underscore.
  • Identifier begins with the alphabets or underscores (_).
  • Identifier cannot begin with the digits (0-9).
  • C# is a case sensitive language that is why upper case and lower case letters are treated separately.
  • Keywords cannot be used as the identifiers. If we want to use the keywords as identifiers then we have to use them with the prefix “@”.
