Code inspection: Method with optional or 'params' parameter is hidden by overload

This inspection reports a method overload whose optional parameter is hidden by another overload. That makes the optional parameter redundant, because a call that omits it resolves to the other overload instead.

Example

                class C
                {
                    void Log(string message)
                    {
                    }
                    void Log(string message, int level = 0)
                    {
                    }
                }
            

                class C
                {
                    void Log(string message, int level = 0)
                    {
                    }
                }
            

Quick-fix

There is no dedicated quick-fix for this inspection. A typical correction is to remove the redundant overload or redesign the overload set so calls are not ambiguous or hidden.
