I recieve "7+" or "5+" or "+5" from XML and wants to extract only the number from string using Regex. e.g Regex.Match() function
stringThatHaveCharacters = stringThatHaveCharacters.Trim(); Match m = Regex.Match(stringThatHaveCharacters, "WHAT I USE HERE"); int number = Convert.ToInt32(m.Value); return number;

If you want to get only digits using REGEXP, use the following regular expression( ^[0-9]*$) in where clause. Case 1 − If you want only those rows which have exactly 10 digits and all must be only digit, use the below regular expression.
Python Regex – Get List of all Numbers from String. To get the list of all numbers in a String, use the regular expression '[0-9]+' with re. findall() method. [0-9] represents a regular expression to match a single digit in the string.
To find whether a given string contains a number, convert it to a character array and find whether each character in the array is a digit using the isDigit() method of the Character class.
\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+"

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 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
