C # method parameters

In C #, you have four types of method parameters:Value, ref, out, And Params.

1. The default parameter type is value.

2. If you want calling code to see changes to a value type variable, the parameter type shocould be ref. Ref parameters definitely must be assigned before passing them to a method.

3. out parameters besides using return statements, another way to return information from a method is via out parameters. you wowould typically use an out parameter if the return value was already being used for another purpose.

The purpose of a Params parameter is to allow you to create methods that will accept avariable number of arguments.
