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++`` method of a class/struct takes a parameter without using it.

== Noncompliant Code Example

|
|
|
----
|
|
private void DoSomething(int a, int b) // "b" is unused
|
|
{
|
|
Compute(a);
|
|
}
|
|
|
|
private void DoSomething2(int a) // value of "a" is unused
|
|
{
|
|
a = 10;
|
|
Compute(a);
|
|
}

== Exceptions
|
|
|
|
This rule doesn't raise any issue in the following contexts:
|
|
|
|
* The ``++this++`` parameter of extension methods.
|
|
* Methods decorated with attributes.
|
|
* Empty methods.
|
|
* Methods which only throw ``++NotImplementedException++``.
|
|
* Main methods.
|
|
* ``++virtual++``, ``++override++`` methods.
|
|
* interface implementations.
