Much before Optional Parameters came in, C# developers used to depend on Method Overloading for mimicking Optional Parameters. Consider a scenario where both exists, what would be the output ? The output would be : The reason behind this … Continue reading Evil Code 0002 Optional Parameter Vs Method Overloading
