Class System.String

Strings are defined as variable-length character buffer. Strings are immutable i.e. once created, the contents of a string do not change. Unlike all other base data types, strings are Reference Type not Value Type. It implements 4 interfaces - IComparable, IConvertible, IClonable, IEnumerable. By Index we mean the position of the characters. The first character of the string is at Index zero.
