Refactoring – Remove Parameter

Refactoring is a disciplined technique of restructuring your existing body of code by altering its internal structure without changing its external behavior.

The Remove Parameters refactoring is quite self-explanatory: an existing parameter is removed from a method's signature. When you choose to remove a parameter, it is especially important to preview the results of refactoring since it will affect each and every invocation of the method.
