Question

For some reason Visual Studio has every property and method of ArrayList except the Item property(it will not appear in the auto complete box). It will not compile when I use it anyway.

Answer 1

The Item property in C# is accessible through the square brackets operator. For example, if the documentation for List<T> says that a class exposes property Item that takes an int and returns a T. You can use it like this:

var res = myList[123];
