find and delete tuple from list of tuples in C# 4.0

Question

I have created a list of tuples:

static List<Tuple<string, string>> Alt;

The user adds to this list:

Alt.Add(new Tuple<string, string>(tbAlt.Text, ""));

What is the best way to find a Tuple based on the first string (i.e. the tbAlt.Text ) and either delete it or modify the second string?

I am new to using Tuples and lists :)

Many thanks for any help!

Answer 1

It appears the first string must be unique or you would not find a (singular)

Why are you using List<Tuple<string, string>>?

Why not Dictionary<string,string>?

Dictionary<TKey, TValue>.ContainsKey is very very fast.

Dictionary.ContainsKey
