Sorting a SortedDictionary based on value, not key

Question

I have a SortedDictionary, the key is a int value and the matching value to each key is a class object. The class contains a int and a two datetime variable.

Answer 1

Sorted Dictionary will always sort on the key, so there is no way to re-arrange it's data so they are sorted on anything other that the key. What you can do is get the data into another structure (some kind of IOrderedEnumerable) where they can be sorted on things other that the key.

If you want to discard the keys and just get the values then

var sortedValues = dictionary.Values.OrderBy(busDetail => busDetail.InTime);

will work, and the type of sortedValues will be IOrderedEnumerable. If you still need to keep both the keys and values, you could do:

var sortedElements = dictionary.OrderBy(kvp => kvp.Value.InTime);

which will return a IOrderedEnumerable>. You can that foreach on any of these two collections, or you could bind them to a grid's datasource.
