== Why is this an issue?
|
|
|
|
Unused parameters are misleading. Whatever the values passed to such parameters, the behavior will be the same.
|
|
|
|
|
|
This rule raises an issue when a ``++private++`` procedure of a ``++Class++``, ``++Module++`` or ``++Structure++`` takes a parameter without using it.
|
|
|
|
=== Noncompliant code example
|
|
|
|
[source,vbnet]
|
|
----
|
|
Private Sub DoSomething(ByVal a As Integer, ByVal b as Integer) ' "b" is unused
|
|
Compute(a)
|
|
End Sub
|
|
|
|
Private Function DoSomething2(ByVal a As Integer, ByVal b As Integer) As Integer ' "a" is unused
|
|
Compute(b)
|
|
Return b
|
|
End Function

=== Exceptions
|
|
|
|
This rule doesn't raise any issue in the following contexts:
|
|
|
|
|
|
* Procedures decorated with attributes.
|
|
* Empty procedures.
|
|
* Procedures which only throw ``++NotImplementedException++``.
|
|
* Main methods.
|
|
* ``++virtual++``, ``++override++`` procedures.
|
|
* Interface implementations.
|
|
* Event handlers.
