Creating a non 0 based array

C# arrays are zero-based index ones

The only way I know of creating a non zero base index array is by using Array.CreateInstance

// create a 1 dimensional array of type int with 5 elements with a starting index of 1.
Array myArray = Array.CreateInstance(typeof(int), new int[1] { 5 }, new int[1] { 1 });
// store 10 to the array with index 1.
myArray.SetValue(10, 1);
// store 9 to the array with index 0. this will produce an error because our staring index is 1.
myArray.SetValue(9,0);
