It’s not always easy to sort out C#’s variables. The following table offers a comparison of all C# variable types except integer and floating point, which are covered elsewhere.

Type	Range	In Use
decimal	Up to 28 digits	decimal d = 123M;
BigInteger	NA	Too humongous to list.
char	0 to 65,535 (codes in the Unicode character set)	char x = 'c'; char y = '\x123'; char newline = '\n';
string	From Empty (“”) to a very large number of characters in the Unicode character set	string s = "my name"; string empty = "";
bool	True and False	bool b = true;
Dynamic	Determined at runtime	Dynamic f = foo()
