Help with saving or adding more than 4000 words to a List<T> in .NET

Question

I need help with my application where i save a bunch of words like more than 4000 words or more in a List<[class name]>.

My problem is, as the number of words increases, the process in saving it in the list seems to go slower and the application uses a lot more of memory.
Can you give me an advise or alternative to do this without affecting the speed of the process?

I bet you're doing lots of searches through your list and finding things slow down as the list grows. I think you want a Dictionary instead of a List. Instead of adding elements to the list, you would use those values as keys in the dictionary (you can use null as the values).
