将string []转换为List <KeyValuePair<int, string> &gt;

Question

I have this strig[] :

string[] SkippedAreasArray = new string[] {"A", "B", "C", "D", "E", "F", "G",
            "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q"};

I want to turn this into :

 List<KeyValuePair<int, string>>  SkippedAreasArray  = ???

I haven't been working with this List<KeyValuePair<int, string>> data structure. So I have to questions how would my string array looked like if I turn it to List<KeyValuePair<int, string>> (how to define it?). And also - my logic is heavily depending on the indexes that are easily taken when I work with simple string[] . The idea to use List<KeyValuePair<int, string>> is that I may need to use values like "A1" , "B1" , "B2" and I understand List<KeyValuePair<int, string>> is the better data structure to easily add those when I need but can I keep the correct indexing of the elements?

Answer 1

Is this what you are looking for:

string[] SkippedAreasArray = new string[] {"A", "B", "C", "D", "E", "F", "G",
"H", "I", "J", "K", "L", "M", "N", "O", "P", "Q"};
Dictionary<int,string> dictionary =
                 SkippedAreasArray.Select((r, i) => new { value = r, index = i })
                 .ToDictionary(t => t.index, t => t.value);

where key is the index and value is the alphabet.

OR

List<KeyValuePair<int, string>> list =
    SkippedAreasArray.Select((r, index) => new KeyValuePair<int,string>(index, r))
    .ToList()

;
