Extracting digits from string

I'm trying to extract some digits from a string: foo=bar&hash=00000690821388874159\";\n

I tried making a group for the digit, but it always return an empty string.

string matchString = Regex.Match(textBox1.Text, @"hash=(\d+)\\").Groups[1].Value;

I never use regex, so please tell me what I'm missing here.

There is no \\ in your string, the \ is in fact used to escape a quote so that's why the regex doesn't match. This works:

string matchString = Regex.Match(textBox1.Text, @"hash=(\d+)""").Groups[1].Value;
