The type in your List must implement the IComparable interface in order for the Sort to be able to work. I just checked and ServiceController does not seem to implement that interface ... so I don't think that's going to work for you at all.

I can think of three workarounds off the top of my head (haven't tried either one):

1) Have two Lists, one that is simply a list of names of the services that you can sort, then of course you'd have to find the corresponding service in your Services list.

2) Use a Dictionary or a SortedDictionary, where the Key is the ServiceName and the Value is the actual Service class.

3) Use a SortedList.
