Can anybody tell me whats the best approach to resolve contact names.

In native phone when a number is dialed, it resolves the number with contact and displays quickly.

But when I do this in my application it takes a lot of time..(with more than 300 contacts)

I am enumerating all contacts and going through each of them and comparing.

is there any way to do this more efficiently?

Maybe the use of a hashtable could make it faster. key: phone number, value Name

then you only have to create it once and update from time to time...
