Maintainability Rules

Cause

A C# file contains code which is unnecessary and can be removed without changing the overall logic of the code.

Rule Description

A violation of this rule occurs when the file contains code which can be removed without changing the overall logic of the code.

For example, the following try-catch statement could be removed completely since the try and catch blocks are both empty.

 

    try

    {

    }

    catch (Exception ex)

    {

    }

The try-finally statement below does contain code within the try block, but it does not contain any catch blocks, and the finally block is empty. Thus, the try-finally is not performing any useful function and can be removed.

 

    try

    {

        this.Method();

    }

    finally

    {

    }

As a final example, the unsafe statement below is empty, and thus provides no value.

 

    unsafe

    {

    }

How to Fix Violations

The fix a violation of this rule, remove the unnecessary code, or fill in the code with additional statements.
