Regex, this is your mission if you choose to accept it – TheGeneral Oct 14 '21 at 09:09

or use split if the same string structure – langme Oct 14 '21 at 09:10

The easiest way is to create an array of the single strings by splitting the string with a loop and an if-condition. – AztecCodes Oct 14 '21 at 09:15

This code might work:
string input = "ADDRESS 47, 0, 2, 0, 1, 0";
string numbersOnly = input.Substring("ADDRESS ".Length);
string[] parts = numbersOnly.Split(", ");
string result = parts[2];
First, you create a substring that doesn't contain the prefix (not necessary if you are not interested in the first number). After that, you split your string into parts. Chose the part with index 2 to get the third number.
If you want to do calculations with the number, you have to convert it into an integer. Replace the last line with
int result = int.Parse(parts[2]);

2You probably want to call `int.Parse(...)` on `parts[2]`. Also, there is no real need to remove the prefix `"ADDRESS "` before splitting, if we're only interested in the third number anyway. – Stef Oct 14 '21 at 09:16
