Value Parameters

Value parameters are - by far - the most frequently used parameters of methods in C#.

Value parameters are used for input to methods

  • Value parameter passing:

    • A formal parameter corresponds to a local variable

    • A formal parameter is initialized by the corresponding argument (the value of the actual parameter expression)

      • A copy of the argument is bound to the formal parameter

    • Implicit conversions may take place

    • A formal parameter is assignable, but with no effect outside the method

Assignments to a formal value parameter do not affect the corresponding actual parameter
