Initializing an array on arbitrary starting index in c#

Question

Is it possible in c# to initialize an array in, for example, subindex 1?

I'm working with Office interop, and every property is an object array that starts in 1 (I assume it was originally programed in VB.NET), and you cannot modify it, you have to set the entire array for it to accept the changes.

As a workaround I am cloning the original array, modifying that one, and setting it as a whole when I'm done.

But, I was wondering if it was possible to create a new non-zero based array

Answer 1

It is possible to do as you request see the code below.

// Construct an array containing ints that has a length of 10 and a lower bound of 1
Array lowerBoundArray = Array.CreateInstance(typeof(int), new int[1] { 10 }, new int[1] { 1 });

// insert 1 into position 1
lowerBoundArray.SetValue(1, 1);

//insert 2 into position 2
lowerBoundArray.SetValue(2, 2);

// IndexOutOfRangeException the lower bound of the array 
// is 1 and we are attempting to write into 0
lowerBoundArray.SetValue(1, 0);
