Question

I have a set of elements/keys which I’m reading from two different config files. So the keys may be same but with different values associated with each of them.

I want to list them in the sorted order. What can I do ? I tried with SortedList class but it does not allow duplicate keys.

How can I do it?

e.g Lets say I have 3 elements with keys 1,2,3. Then i get one more element having key 2 (but different value). Then I want the new key to get inserted after existing key 2 but before 3. If I againg find an element with key 2, then it should go after most recently added key 2.

Please note than I’m using .NET 2.0

I prefer to use LINQ for this type of thing:

using System.Linq;

...

var mySortedList = myList.Orderby(l => l.Key)
                         .ThenBy(l => l.Value);

foreach (var sortedItem in mySortedList) {
    //You'd see each item in the order you specified in the loop here.
}

Note: you must be using .NET 3.5 or later to accomplish this.
