Get a certain String from text

Question

How do you get this string from this data? (The bolded part is what I want)

Id: 20 - Cow Amt: **10**

Id: 25 - Example Amt: **5**

I made this code to remove everything else except for the ID number

id = id.Replace("Id: ", "")

If (id.ToString.Length > 5) Then
    id = id.Substring(0, id.IndexOf("-") - 1).Trim()

But now I want to also get the Amt: number as well. The outcome of the code so far is this:

20

It just prints out the id. But how do you get the 10? So it would look like this:

20 10

what about a simple loop? find where the 'A' of "Amt" is and print from there. — elyashiv, Aug 18 '12 at 18:00
what's the meaning of `Cow` in this data? Your string doesn't seem to have a specific rule — codingbiz, Aug 18 '12 at 18:09
I'd recommend going for regular expressions matching only numbers (thus, you'd get 2 matches: 20 and 10; though it may change if your unnecessary text will contain numbers also). Here's SO post: http://stackoverflow.com/questions/273141/regex-for-numbers-only — Dmitry Reznik, Aug 18 '12 at 18:12
the tag and the title a confusing... are you asking for vb.net or c# or don't you care as long as it is in the .net family? — psubsee2003, Aug 18 '12 at 18:51

Try the following

var subjectString = "Id: 20 - Cow Amt: 10";

string[] values = Regex.Split(subjectString, @"\D+");

foreach (string value in values)
{
    int number;
    if (int.TryParse(value, out number))
    {
        Console.WriteLine(value);
    }
}
