How do I Sort a List of Classes by a property?
I have a List of my Class
var Events = List.<Evnt>();
where the Class Evnt has a property enentTime
public class Evnt{
//properties
var eventNo :int;
var eventTime :float;
//Constructor
public function Evnt(evn:int,evt:float){
this.eventNo = evn;this.eventTime = evt;
}
}
I want to sort this List by eventTime. If I call Events.Sort() I get an error - ArgumentException: does not implement right interface. How can I sort a List in this manor? Thank You.
Yes. I can sort a list of ints using simply Sort(). I need the right code to sort by eventTime - Events.Sort(); Events.Sort(eventTime); Events.Sort(Evnt.eventTime); all give errors. What do I need to put in the parenthises?
You have to write your own comparison method that returns whether an object is "equal", "greater than" or "less than". Check the examples found on those pages.
You'll want to use the List.Sort method with a simple delegate. You can write your own custom delegate if you need advanced ordering. Details on MSDN page for Sort.
myList.Sort(delegate(int a, int b) {
return a.CompareTo(b);
});
