Rate this:

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

Hi Manoj,

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!-<>@;',.", ""));
