Identifiers and Keywords
Identifiers are names programmers choose for their types, methods, variables,
etc. An identifier must be a whole word, essentially made up of Unicode characters
starting with a letter or underscore, and may not clash with a keyword. As
a special case, the @
prefix may be used to avoid a clash
with a keyword, but is not considered part of the identifier. For instance,
the following two identifiers are equivalent:

C# identifiers are case-sensitive, though for compatibility with other languages, you should not differentiate public or protected identifiers by case alone.
