.NET Forum / .NET Framework / CLR / May 2004ArrayList Sort Terminating
Project C# utilizing the Framework In my project I have an array list of integers that sorts just fine. Then I have an array list that contains a class that I have built. When I call the "sort" method of the array list and accept the defualt sort arraylist.sort() I get the following error message: "At least one object must implement IComparable.". Does this mean I am going to have to override the compare function and implement my own compare to function for the sort ?

Not override, implement. Your class should implement the IComparable interface. How else could the sort algorithm know how to order the objects of the class? Fabian You can also use the sort method which takes a IComparator as parameter.
