Question

Trying to understand Pointer Arithmetic when dealing with arrays. It seems to me they’re used for fast access of arrays, but maybe I’m totally wrong. I mean if we have this:

*(myArray + 1), we’re going to the next location in the array I think.

I’m converting some C++ to C# and the C++ has pointer arithmetic going on. I need the C# to be totally managed so trying to figure out how to translate the pointer stuff to C#.

THanks for any ideas.

If you’re not completely comfortable with pointers, your life will be a bit easier in C#. First off, the code you posted:

`*(myArray + 1)`

Your understanding is basically correct, you are dereferencing the 1st element in myArray. Or in other words, accessing myArray[1].

Moving to C#, you likely use a generic List<T> where T is the type of your myArray. Similar syntax is available to you – myArray[i], plus many more functions on the List.
