Sort element lines by a sum VB.Net - vb.net

Question

Can i short a textbox by a sum lines? example: I have textbox:
Textbox1.Lines(0)= 1 10
Textbox1.Lines(1)= 1 11
Textbox1.Lines(2)= 2 10
Textbox1.Lines(3)= 3 11
Textbox1.Lines(4)= 2 12
Expected Output: preferably if possible, write the sum that is. with :( sum = x) preferably short by descending, probably an example of sorting code would help me, but I can do that too, but for now I don't know how to order according to the sum of the lines. just to sort them out, this would be a model, but to know the sum of each one as well.
{ LstScan = 2 12, DrwSum = 14 }
{ LstScan = 3 11, DrwSum = 14 }
{ LstScan = 2 10, DrwSum = 12 }
{ LstScan = 1 11, DrwSum = 12 }
{ LstScan = 1 10, DrwSum = 11 }

Answer 1

In c# this would look like:
var list = new[] { "2 12", "3 11", "2 10", "1 11", "1 10" }
.Select(o => Tuple.Create<string, int>(o, o.Split(' ').Sum(x => int.Parse(x))));
var result = list.OrderByDescending(o => o.Item2).ToList();
In vb.net it would be:
Dim list = {"2 12", "3 11", "2 10", "1 11", "1 10"}
.[Select](Function(o) Tuple.Create(Of String, Integer)(o, o.Split(" "c).Sum(Function(x) Integer.Parse(x))))
Dim result = list.OrderByDescending(Function(o) o.Item2).ToList()
