Code inspection: Redundant condition check before assignments

This inspection reports an if check that only prevents assigning a value that is already equal to the current one. The extra comparison is redundant because the same assignment can be made directly.

Example

            class C
            {
                void SetValue(ref int current, int next)
                {
                    if (current != next)
                    {
                        current = next;
                    }
                }
            }
        

Quick-fix

There is no dedicated quick-fix for this inspection. The usual fix is to remove the check and keep the assignment, unless the comparison is intentionally documenting behavior.
