How to convert SortedList to some other type of same kind?

I have some thing like below.
System::Collections::Generic::SortedList ^ franges;

But i wrote hell a lot of code using this. Now i don't want the list to be sorted.
So can I change the this SortedList to some other type of same kind.
For example Dictionary or IDictionary can be used in similar way.
Similar to these types i want some other of this kind except Dictionary.

Accepted answer
To access the individual components of (say) the first element of the List:

UInt16 key = list[0].Key;
UInt16 value = list[0].Value;

or, to iterate the list:

for each (KeyValuePair kvp in list)
{
Console::WriteLine("Key = {0}, Value = {1}", kvp.Key, kvp.Value);
}

Ok i will consider your initial as you suggest.
But how should i be accessing Keys and values from the same.

You can't - information about the corresponding keys has been lost.

You could create a separate list of the keys (use franges->Keys instead of Values) which, initially, would be in the same order as the corresponding values. However, if you deleted items or inserted new ones, then you'd need to make corresponding changes to both lists to keep them synchronized.

Of course, if you go for my original suggestion, then the keys are still there as part of the KeyValuePairs within the List.

Got it but how to access Keys and Values from the same now?

Previously i was doing like franges->Keys[ranges_index] looks like i will not be able to do the same here.

It's a List of all the KeyValuePairs in the SortedList but is no longer automatically sorted when new KeyValuePairs are added to the list - they're just added at the end.

If you don't want the keys, then you can create a List of the values, like this:

List^ listValues = gcnew List(franges->Values);

what is this?
I want to remove whole of SortedList and add some thing newly of its kind.
But your declaration shows something which is franges which is a sortedlist.
Or else if there is some thing which can make the sorted list unsorted is also fine.

If you don't want to convert it to a Dictionary, then you can convert it to a List of KeyValuePairs:

using namespace System::Collections::Generic;

// ....

List>^ list = gcnew List>(franges);
