Parameters

Actual parameters occur in a call. Formal parameters occur in the method declaration. In general, actual parameters are expressions which are evaluated to arguments. Depending on the kind of parameters, the arguments are somehow associated with the formal parameters.

Introduction to Methods in C#.

There are four different kinds of formal parameters in C#:
- Value parameters
  - The default parameter passing mode, without use of a modifier
- Reference parameters
  - Specified with the ref modifier
- Output parameters
  - Specified with the out modifier
- Parameter arrays
  - Value parameters specified with the params modifier
