Finding spelling of an element in an ignore case dictionary

Question

Hi,

Weird question, but I have a dictionary created with StringComparer.OrdinalIgnoreCase, looks something like this

AaA, 10
aAB, 20
AAC, 12

I then use myDictionary["AAA"] to find the value associated with the key, but what I also need to know is what the actual spelling of the key is in myDictionary, e.g. in this case I want it to return AaA. Any way to do this without a loop? Thx.

Answer 1

string value = myDictionary.First(v => StringComparer.Create(CultureInfo.CurrentCulture,true)
                  .Compare(v.Key,"AAA") == 0)
                  .Key

Answer 2

Change your dictionary so it looks like this:

public struct myValue
{
    int myInt;
    string MixedCaseWord;
}

var dictionary = new Dictionary<string, myValue>(StringComparer.OrdinalIgnoreCase);

var key = "AaA";
dictionary.Add(key, new MyValue { myInt = 10, MixedCaseWord = key }); 

var correctSpelling = dictionary["AAA"].MixedCaseWord;
