If you re using  NET 3 5 or  NET 4  it s easy to create the dictionary using LINQ   Dictionary lt string  ArrayList gt  result   target GetComponents                                          ToDictionary x   gt  x Key  x   gt  x Value     There s no such thing as an IEnumerable lt T1  T2 gt  but a KeyValuePair lt TKey  TValue gt  is fine
