Vulpes · Answer

The string type is perhaps the best known example of an immutable type in .NET. Methods which appear to alter a string (Insert Replace Remove etc) do in fact produce a new string as neither the length nor content of the existing string can be changed.

Immutable type A type whose instance data fields and properties does not change after the instance is created. Example : class Rectangle { private readonly long _length _width; public Rectangle ( long length long width ) { _length = length; _width = width; } public virtual long Length { get { return _length; } } public virtual long Width { get { return _width; } } } class Square : Rectangle { public Square ( long width ) : base ( width width ) { } } The example class is immutable because the Length and Width properties of Rectangle do not use the set keyword.
