adding arraylist to another arraylist with different values

I have a dataset with 2 tables, so I declared 2 ArrayList and fetching that table values from DataSet into two ArrayLists.

One ArrayList has the count of 66, another of 37.

Now, how do I combine these ArrayLists into one ArrayList so that I get values of both ArrayList into an single ArrayList?

Linq style:

IList<int> both = arrlist1.Cast<int>().Concat(arrlist2.Cast<int>()).ToList();

You can use the AddRange method. But you shouldn’t use ArrayLists, they are deprecated. Use the generic List class instead.

Furthermore, are you sure you need the separate values at all? Aren’t the data sets enough?
