C # identifier
- Identifier is used to identify the class, variables, functions, or any other user defined items. (Popular to say that the class name, variable names, function names, etc.) in C #, class names must follow the following basic rules:
- The identifier must begin with a letter, underscore, or @, can be followed by a series of letters, numbers (0--9), underscore (_), @.
- Identifiers of the first character can not be a number.
- Identifier must not contain any embedded spaces or symbols, such as - + #% ^ & * () [] {};:?! ' "/ \.
- Identifiers can not be C # keywords. Unless they have a @ prefix. For example, @ if a valid identifier, but if not, because if a keyword.
- The identifier must be case-sensitive. Uppercase and lowercase letters are considered different letters.
- Not the same as the library name to C #.
