Solution 1

For the 1st question :
Here you can use the Method Split with the ',' as delimiter.
Split delivers you a String-Array with all elements from the source seperated.

For the 2nd question :
You must explain what the goal shall be - which Output do you Need ?

Hello
for the first question it is enough :
using System;

public class SplitTest {
public static void Main() {

string words = "This is a list of words, with: a bit of punctuation" +
"\tand a tab character.";

string [] split = words.Split(new Char [] {' ', ',', '.', ':', '\t' });

foreach (string s in split) {

if (s.Trim() != "")
Console.WriteLine(s);
}
}
}

I found code to read word by word :
int i = 0;
foreach (string line in File.ReadAllLines("path to text file"))
{
string[] parts = line.Split(',');
foreach (string part in parts)
{
MessageBox.Show(part);

}
i++; // For demo only
}

Start with either string.Split to break the strings, and use int.TryParse to convert the values you need; or use a CSV processor to read the strings: A Fast CSV Reader[^] is a good starting base.

From that, it's pretty simple to calculate values - but you would have to work out exactly what you want to do: we can't give you explicit instructions for generic questions.
I'd suggest you start by looking at the List<T> class to assemble your output results, though.
