Regex to get NUMBER only from String
Solution 1:
The answers above are great. If you are in need of parsing all numbers out of a string that are nonconsecutive then the following may be of some help:
string input = "1-205-330-2342";
string result = Regex.Replace(input, @"[^\d]", "");
Console.WriteLine(result); // >> 12053302342
Solution 2:
\d+
\d represents any digit, + for one or more. If you want to catch negative numbers as well you can use -?\d+.
Note that as a string, it should be represented in C# as "\\d+", or @"\d+"
