Whats the point of SortedList.IndexOfKey

So you pass in the Key and it returns the array index of the key. but you
cant do array index lookups. the indexer of the sortedlist does a binary
search based on the key. So whats the pointof this method? is there a way
to return a array item based on the index?

Hi John,
the SortedList type has a GetByIndex method which allows you to enter the
ordinal position of an item in the list and retrieve the value stored at that
position.

Sorry, i should have been more specific. I'm talking about the 2.0 Generic
SortedList. The 1.1 SortedList does have a GetByIndex. the 2.0 Generic
SortedList does not.

In the SortedList you have the Values collection which can be referenced by
an ordinal position. I guess you could use your index value with that to
return the desired value.

John,

You have:
GetByIndex to ger value by index and GetKey to get key by index.
