Multiple keys in SortedList

[dwm]

Good morning,

 

I am using a SortedList to hold some user-defined types sorted by a key. However, the key might not necessarily be unique, and whenever I try to add an item with a key that already exists in the SortedList, I get an error. I am wondering if there is any way to make the SortedList handle more than one of the same key and just put them "next to each other" (i.e. 1,2,3,3,3,4,5...).

 

Thanks in advance,

dwm

SortedList does not support duplicate keys::MSDN

 

If you can use strings then a NameValueCollection will work. It is a 1 to Many collection. MSDN

Thanks for the reply. I just read up on the NameValueCollection, and the only problem I see is that the object must be a String as well as the key. But looking through the descriptions, it looks like a NameObjectCollectionBase would work for what I'm trying to do. Does that sound correct to you? Does the NameObjectCollectionBase allow a 1-to-many relationship using objects?

 

Thanks again,

The abstract class NameObjectCollectionBase would allow you to create your own implementation.

The key would be strings and the values objects. Reference
