Modifying string using Regex

Question

I'm trying to modify the following string using System.Text.RegularExpressions.Regex in C#, and I need to replace /(integer)x(integer)/ with /. For example in url, I need to replace /1080x1080/ to /. How can I do this? I studied regex but I couldn't figure out how to do it.

string url = "https://scontent-icn1-1.cdninstagram.com/t51.2885-15/1080x1080/22158936_1794137857546339_3682912105310191616_n.jpg";
//The link is actually invalid because I modified it

See msdn for good reference : learn.microsoft.com/en-us/dotnet/standard/base-types/… — jdweng

You can match in following way :

/\d+x\d+/

Replace the matching with your replacing string.

In C#, you can use Regex Replace method in following way :

string output = Regex.Replace("your_string", @"/\d+x\d+/", "/");

You can replace the string using Regex.Replace:

string url = "https://scontent-icn1-1.cdninstagram.com/t51.2885-15/1080x1080/22158936_1794137857546339_3682912105310191616_n.jpg";
url = Regex.Replace(url, @"/\d+x\d+/", "/");
