Select Value of List of KeyValuePair

Question

How can i select the value from the List of keyvaluepair based on checking the key value

List<KeyValuePair<int, List<Properties>> myList = new List<KeyValuePair<int, List<Properties>>(); 

Here I want to get the

list myList[2].Value when myLisy[2].Key=5. 

How can i achieve this?

Answer 1

If you need to use the List anyway I'd use LINQ for this query:

var matches = from val in myList where val.Key == 5 select val.Value; foreach (var match in matches) {     foreach (Property prop in match)     {         // do stuff     } } 

You may want to check the match for null.

Answer 2

If you're stuck with the List, you can use

myList.First(kvp => kvp.Key == 5).Value 

Or if you want to use a dictionary (which might suit your needs better than the list as stated in the other answers) you convert your list to a dictionary easily:

var dictionary = myList.ToDictionary(kvp => kvp.Key); var value = dictionary[5].Value;
