"I have an Array list with an Id and a value in it."
Please clarify. Are this two separate lists?

The array list is populated from a list box with an Id and description. I just need to access the Id. I know its prob just something but it's been a long day.;)

Hi,
if you'd like to access the value in arraylist by index, just do it as in any regular array:

C#

var value = newListOfIds[index];

Anyway I would recommend to iterate over the values in array by using foreach constructs, as accessing over an index is more expensive in terms of running time.

C#

foreach(var value in _newListOfIds){
/*operate with value variable*/
}
