#20 – Literals

A literal in C# is a representation, in your source code, of a constant value.  You can use literals when assigning a value to a variable, when passing a parameter value to a method, or wherever a variable of the corresponding type is expected.

C# defines six different types of literals:

• Boolean literal:  true | false
• Integer literal:  e.g. 12, 24L, 100UL, 0x7DC
• Real literal:  e.g. 1.0, 2.2F, 4, 6.02E23, 123.45m
• Character literal:  e.g. ‘a’, ‘Z’, ‘#’, ‘\n’, ‘\”, ‘\\’, ‘\x45′, ‘\x04DA’
• String literal: e.g. “Sean”, @”Print\nMe”, “Look: \x04DA”, “Look: Ӛ”, “Line 1\nLine 2″
• Null literal:  null
