Identifiers

Identifiers are the names that developers choose for namespaces, types, type members, and variables. In C# and VB.NET, identifiers must begin with a letter or underscore and cannot be the same name as a reserved keyword. Microsoft no longer recommends the use of Hungarian Notation (e.g., strName, nYear) or delimiting underscores (e.g., Temp_Index) when naming identifiers.
