Invert Boolean refactoring

This refactoring allows you to automatically modify a boolean member so that its value is inverted. If you apply this refactoring to a boolean field or a property, ReSharper lets you specify a new name and invert all its usages, that is if you refactor private bool isEnabled; to private bool isDisabled;, ReSharper will make sure that, for example, if(isEnabled) becomes if(!isDisabled) everywhere.

If you apply this refactoring to a boolean method, ReSharper lets you choose whether to invert its internal logic, usages, or both.

In the example below, we use this refactoring to invert the IsEven method. We specify a new name IsOdd and choose to invert both the internal logic and usages:

public bool IsEven(int input)
{
  return input % 2 == 0;
}
public void Test(int value)
{
  if (IsEven(value))
    Console.WriteLine("\n the number is even");
}

public bool IsOdd(int input)
{
  return input % 2 != 0;
}
public void Test(int value)
{
  if (!IsOdd(value))
    Console.WriteLine("\n the number is even");
}
