Why can‘t .Sort() not be called via the Name of the Array? E.g. arrayName.Sort?

No sum is a extension method of linq. This is the power of extension methods. It look like, it is a class method but it is not. comment out using linq in the code below. You will see that sum is no longer a part of the array class https://code.sololearn.com/cO4oym2R0Wl3/?ref=app https://www.csharp-examples.net/linq-sum/ https://www.tutorialsteacher.com/csharp/csharp-extension-method

Marvin Because Sort() is a static method of Array class which needs one parameter as an array to sort array like this: int[] arr = {1, 5, 4, 6}; Array.Sort(arr); for (int i = 0; i < 4; i++) Console.Write(arr[i]);

Marvin No Sum() is not a method of Array class. You can see here which method exist in Array class. https://docs.microsoft.com/en-us/dotnet/api/system.array?view=net-5.0
