有没有更好的方法来重构此方法？

Question

The method should return false if the bool is true and the length of array is not equal to 27 or if the array value 25 is empty.

The method should also return false if the bool is false and the length of array is not equal to 28 or if the array value 26 is empty

  private static bool IsValid(string[] values, bool isFullFile)
        {
            if (isFullFile && (values.Length != 27 || values[24] == string.Empty))
            {
                return false;
            }

            if (!isFullFile && (values.Length != 28 || values[25] == string.Empty))
            {
                return false;
            }

            return true;
        }

Answer 1

This can be simplified enough to use an Expression body definition

private static bool IsValid(string[] values, bool isFullFile)
    => isFullFile 
        ? (values.Length == 27 && values[24] != string.Empty) 
        : (values.Length == 28 && values[25] != string.Empty);

(Forgive me for answering this, because this really belongs in code review.)
