I want to delete all the characters other than letter and number from a given string. I used the pattern below but it still returns string without any change.
Regex rex = new Regex("/[^a-zA-Z0-9]+/");
Response.Write(rex.Replace("asd123!-<>@;',.", ""));
It suppose to return "asd123"
Regex patterns are like alien language to me and I dont know how to fix this.
Thanks
In C#, you don't need to delimit regex patterns with / characters.
Try this:
Regex rex = new Regex("[^a-zA-Z0-9]+");Response.Write(rex.Replace("asd123!-<>@;',.", ""));
