RegEx从C＃中的字符串中删除十六进制字符

Question

There are some hexadecimal values hidden in some of my DB values that are causing me some trouble, does anyone have a RegEx to clean these out?

Here is the error i am getting:

'', hexadecimal value 0x19, is an invalid character.

This post explains my problem completely but I am looking for a RegEx solution: http://seattlesoftware.wordpress.com/2008/09/11/hexadecimal-value-0-is-an-invalid-character/

Answer 1

Instead of building XML strings by concatenation, you should use the XML handling classes provided with .NET. These will properly encode dangerous characters as XML entities and produce well-formed XML.

Also, regular expressions don't do well for XML processing.

Do you need something like....

    Regex regex = new Regex("0x\\d\\d");

    String Input = "this0x34is my 0x45 test 0x11";

    string Result = regex.Replace(Input, " ");

I know you're hoping for Regex, but have you tried System.Security.SecurityElement.Escape ? I believe this method is specifically intended for your use case.
