Answer 1

ok check this it should work

var r = new Dictionary<string, Point>();
r.Add("c3", new Point(0, 0));
r.Add("c1", new Point(0, 0));
r.Add("t3", new Point(0, 0));
r.Add("c4", new Point(0, 0));
r.Add("c2", new Point(0, 0));
r.Add("t1", new Point(0, 0));
r.Add("t2", new Point(0, 0));
var l = r.OrderBy(key => key.Key);
var dic = l.ToDictionary((keyItem) => keyItem.Key, (valueItem) => valueItem.Value);

foreach (var item in dic)
{

    Console.WriteLine(item.Key);
}
Console.ReadLine();
