Shortest code to calculate list min/max in .NET

Question

I\'d like something like

int minIndex = list.FindMin(delegate (MyClass a, MyClass b) {returns a.CompareTo(b);});

Is there a builtin way to

Well, if you can't use .NET 3.5, you could always sort the list and then return list[0]. It might not be the fastest way, but it's probably the shortest code, especially if your class already implements IComparable.

List list = new List();
// populate the list
// assume that SomeClass implements IComparable
list.Sort();
return list[0];               // min, or
return list[list.Count - 1];  // max

This also assumes, of course, that it doesn't matter which item you return if you have multiple items that are the minimum or maximum.

If your class doesn't implement IComparable, you can pass in an anonymous delegate, something like this:

list.Sort(delegate(SomeClass x, SomeClass y) { return string.Compare(x.Name, y.Name); });
