Storing duplicate key value pairs in C#

Question

I have a data like in (string , int) pair. How to store this data in collection object. Both values can be duplicate. Which collection object should i use??

Answer 1

You can use List<KeyValuePair<string,int>>.

This will store a list of KeyValuePair's that can be duplicate.

Answer 2

You can use List<KeyValuePair<string, int>> if you want to add & remove items, or KeyValuePair<string, int>[] if the number of items is known

Answer 3

If you want to avoid repeating the key for multiple values you can use Dictionary<string, List<int>>.
