parse (find) number in the text string

How can I find numbers in text string by C#. for example

<Example>
A text string "At the 27th week of Year 1997, 2 cases were reported in 13 areas"

Can I have the return in dynamic array (or array list), which can automatically adjust the size of array.
4 digit is the max. I won't have anything above 4 digit.

so in this example, it will return.
content_array (return those numbers)
1997 --> number with 4 digit
Null --> number with 3 digit
27, 13 --> number with 2 digit
2 --> number with 1 digit

Count_array (return count of numbers)
1--> number with 4 digit
0--> number with 3 digit
2 --> number with 2 digit
1 --> number with 1 digit

Thanks in advance

easiest way is regex, the code would be something like this

string strText = "At the 27th week of  Year 1997,  2 cases were reported in 13 areas";
Regex re = new Regex("[0-9]{1,4}");
//string resultStr = re.Replace(strText, " ");
MatchCollection mc = re.Matches(strText);
foreach(Match m in mc)
{
	MessageBox.Show(m.Length.ToString() + ", " + m.Value);
}

if you don't have MAX 4 digit restriction, you can do this

string strText = "At the 27th week of  Year 1997,  2 cases were reported in 13 areas";
Regex re = new Regex("[0-9]+");
//string resultStr = re.Replace(strText, " ");
MatchCollection mc = re.Matches(strText);
foreach(Match m in mc)
{
        MessageBox.Show(m.Length.ToString() + ", " + m.Value);
}
