Getting a number part from a url string in c#-CodePudding

I have a URL string that is something like below:

https://example.com/app/1095600/example2234

I want to only get "1095600"

this number is variable and can be three or more digits long.

CodePudding user response：

If the number is always in the same position (following https://example.com/app/), you could split the string by the slash (/) character and extract it:

string input = "https://example.com/app/1095600/example2234";
string result = input.Split("/")[4];

CodePudding user response：

You can try matching the required substring with a help of regular expressions, esp. if you have elaborated criteria

three or more digits

Code:

using System.Text.RegularExpressions;

...

string url = "https://example.com/app/1095600/example2234";

string number = Regex.Match(url, @"(?<=\/)[0-9]{3,}(?=\/|$)").Value;
