Code Issues – Redundant Constructor

January 23rd, 2011 Comments off

Cause:

This code issue shows a hint (suggestion) that a redundant constructor can be safely removed. Redundant constructor is a public, parameterless constructors without any code inside of its body. This constructor doesn’t call base type constructors and it is alone in the current class. The constructor is redundant because such constructors are automatically generated by the compiler. Removing the redundant constructors may improve code readability.

Sample:

CodeRush Code Issues - Redundant сonstructor

How to fix:

  • Remove the redundant constructor by applying the corresponding Remove Redundant Constructor refactoring:

CodeRush Redundant Constructor Fix 1

  • Add another constructor to the class, so the original constructor is no longer redundant:

CodeRush Redundant Constructor Fix 2

Code Issues – Field can be read-only

January 23rd, 2011 Comments off

Cause:

This code issue shows a hint (suggestion) on the fields which can be marked as read-only. When a field declaration includes a readonly modifier, assignments to the fields introduced by the declaration can only occur as part of the declaration or in a constructor (instance or static) in the same class. Read-only fields cannot be changed by other code or the code from team members, thus making it less likely to be messed up by someone who doesn’t understand the purpose of the code.

Sample:

How to fix:

The Make Read-only refactoring is a code fix for this issue:

Code Issues – Property cannot have void type

January 22nd, 2011 Comments off

Cause:

A property is a member that provides a flexible mechanism to read, write, or compute the value of a field, thus it cannot have a void type. Properties are actually special methods called accessors (getter or setter) and they must have a specific non-void type according to most language specifications.

Code Issues – Constructor must declare a body

January 21st, 2011 Comments off

Cause:

The Constructor must declare a body code issue shows an error if there is a constructor without a body. Constructors are similar to usual methods and whenever a class or struct is created, its constructor is called. Constructors should always declare its body to properly initialize a class or struct.

Code Issues – Cannot create an instance of interface

January 21st, 2011 Comments off

This code issue shows an error if there is an attempt to initialize an instance of a interface. Interfaces cannot be instantiated, they contain only the signatures of methods, properties or events. The implementation of these members is done in the class that implements the interface.

Code Issues – Abstract member cannot be private

January 21st, 2011 Comments off

This code issue shows an error when an abstract member with the private visibility keyword is found. Abstract members are incomplete, and must be implemented in a derived class. That’s why abstract members can not be private – they must be visible in a derived class.
