lets assume you have class called Table containing two properties list<string> Sore and List<int> aye

public class Table
{
    public String Sore { get; set; }
    public int Aye { get; set; }
}

var table = new List<Table>
                {
                    new Table{  Sore = "A" , Aye = 1},
                    new Table{  Sore = "A" , Aye = 2},
                    new Table{  Sore = "A" , Aye = 3},
                    new Table{  Sore = "B" , Aye = 1},
                    new Table{  Sore = "B" , Aye = 2},
                };
var group = table.GroupBy(q => q.Sore).ToList();
foreach (var g in group)
{
    Debug.WriteLine(g.Key);
    foreach (var i in g)
    {
        Debug.WriteLine("   "+i.Aye);
    }
}

the Output will be:

A
   1
   2
   3
B
   1
   2
