Question

I have a class model somewhat like this:

public class MyModel
{
   long MyModelID { get; set; }
}

I have a list of MyModel objects called TheListOfModels and a list of longs called TheListOfIDs: I want TheListOfModels to be sorted in the same order as TheListOfIDs.

What I have in mind is a loop that goes through the TheListOfIDs and at each iteration adds the corresponding TheListOfModels to a new list called SortedList and then reassigns that list to the original TheListOfModels.

Is this the best way to do it or is there a linq syntax for this specific operation?

Thanks.

This’ll do it:

var q = (from i in TheListOfIDs
        join m in TheListOfModels on i equals m.MyModelID
        select m).ToList();
