Code Issues of the dead code type for members and blocks
Here are several of the code issues, which highlight redundant and unnecessary code blocks that may be safely removed for improving code readability.

Here are some of the code issues of the dead code type that indicate redundant ‘this’ (‘Me’ in VB), ‘base’ (‘MyBase’ in VB) and type qualifiers.
A switch statement executes logic, dependent on the value of a given expression (parameter). The types of values a switch statement operates on can be boolean, enum, integral types, and strings. Each switch statement can contain any number of case statements, but no two case constants within the same switch statement can have the same value. Each case statement defines a value to compare against the original expression. You may also include a default label following all other case statements. If none of the other choices match, then the default choice is taken and its statements are executed. If there is no default label, control is transferred outside the switch.
Cause:
The else statement is redundant when it doesn’t contain any code, and can be safely removed to improve readability. The type of code issue is a dead code.

Cause:
This code issue of a dead code type shows type parameters to a generic type, or method definitions that are not referenced within its scope, and can be removed. In a generic type or method definition, a type parameter is a placeholder for a specific type that a client specifies when they instantiate a variable of the generic type. Removing the unused type parameter may improve readability.
Cause:
Destructors are invoked automatically, and used to destroy instances of classes. The developer has no control over when the destructor is called, because this is determined by the garbage collector. Redundant destructor is a an empty destructor without any code inside, that can be safely removed.
Cause:
This code issue shows a warning when the catch block is empty. Usually empty catch block is a bad idea, because you are silently swallowing an error condition and then continuing an execution of the program, or the program may simply fail for an unknown reason.
In general, when an exception occurs, it can be thrown up to the caller, or it can be caught in a catch block. When catching an exception, it is recommended to inform the user about the problem, or log it for a future review.
Cause:
This code issue shows a dead code when there are unreferenced private property setters. Unused property setters of private properties can be safely removed, which will improve code readability.
