DataTable Key/Value columns to Dictionary

There are undoubtedly more elegant ways to do this using LINQ, but to quickly and easily take the key (int) and value (string) columns from a DataTable and turn them into a Dictionary<int, string>, the following method has come in handy recently:

public static Dictionary<int, string> GetAsDictionary(DataTable data, string keyField, string valueField)
{
    Dictionary<int, string> dictionary = new Dictionary<int, string>();

    foreach (DataRow row in data.Rows)
    {
         dictionary.Add(Convert.ToInt32(row[keyField]), Convert.ToString(row[valueField]));
    }

    return dictionary;
}
