You first need to create a helper class which implements IComparer and code its Compare() method to provide a sort order for your structs. This method should return the following int values when two structs x and y are compared to each other: Less than zero if x is less than y. Zero if x equals y. Greater than zero if x is greater than y. You then need to create an instance of this class and pass it to the overload of ArrayList.Sort() which takes an IComparer parameter. See the MSDN example below (or google for others) to get an idea of how to do this: http://msdn.microsoft.com/en-us/library/0e743hdt.aspx
