In the below example, how to return row have minimum value at element(0) of dictionary?

Dictionary> dictSource2 = new Dictionary>

{

{ 1, new List { "5", "Programmers" }},

{ 2, new List { "12", "Testers" }},

{ 3, new List { "2", "Designers" }},

};

I want to return the following data from above dictionary-

"2", "Designers"

I have written below:

string sminValue= dictSource.Min(pair => pair.Value.ElementAt(0))

But it returns the incorrect results.Note, my solution woks fine when value at ElementAt(0) has zero records. Can anyone guide here?

please find the code here,

Dictionary<int, List<string>> dictSource2 = new Dictionary<int, List<string>> {

 { 1, new List<string> { "5", "Programmers" }},

 { 2, new List<string> { "12", "Testers" }},

 { 3, new List<string> { "2", "Designers" }}, };

var list = dictSource2.Values.Where(x => !string.IsNullOrEmpty(x[0])).OrderBy(x => Convert.ToInt32(x[0])).First();

if (list != null)

  dictSource2.Add(0, list);

the following works exactly what you expect -

Dictionary dictSource2 = new Dictionary();
dictSource2.Add("Programmers", 5);
dictSource2.Add("Testers", 12);
dictSource2.Add("Designers", 2);


var min = dictSource2.Aggregate((l, r) => l.Value < r.Value ? l : r).Key;
Console.WriteLine(min);
