The using control structure

The using control structure is helpful when we do IO programming

using (type variable = initializer)

The syntax of the using statement C#

  • Semantics

    • In the scope of using, bind variable to the value of initializer

    • The type must implement the interface IDisposable

    • Execute body with the established name binding

    • At the end of body do variable.Dispose

      • The Dispose methods in the subclasses of Stream call Close
