Question

I have a dictionary object as under

Dictionary<string, List<string>> dictStr = new Dictionary<string, List<string>>();
dictStr.Add("Culture", new List<string>() { "en-US", "fr-FR" });
dictStr.Add("Affiliate", new List<string>() { "0", "1" });
dictStr.Add("EmailAddress", new List<string>() { "[e-mail]", "[e-mail]" });

And I have an entity as under

public class NewContextElements
{ 
    public string Value { get; set; }
}

What I need to do is that for every value in a particular index of the dictionary value collection, I have to make a comma separated string and place it into List collection.

e.g. the NewContextElements collection will have (obviously at run time)

var res = new List<NewContextElements>();
res.Add(new NewContextElements { Value = "en-US" + "," + "0" + "," + "[e-mail]" });
res.Add(new NewContextElements { Value = "fr-FR" + "," + "1" + "," + "[e-mail]" });

I was trying as

var len = dictStr.Values.Count;
for (int i = 0; i < len; i++)
{
    var x =dictStr.Values[i];
}

no it is of-course not correct.

Help needed

Answer 1

Try this:

Enumerable.Range(0, len).Select( i =>
    new NewContextElements {
        Value = string.Join(",", dictStr.Values.Select(list => list[i]))
    }
);

len is the number of items inside the individual lists (in your example, it’s two).
