Filtering out bad characters using a regular expression

开发者_运维技巧I want to filter out the char ^ before searching something in a database.

What will my regular expression look like if I want to achieve that the query will ignore the sign ^?

I'm working with Visual Studio 2008, .NET 3.5, and C#.

You don't need a regex for that. You can simply do this:

myString = myString.Replace("^", "");

If you want to filter only that character, a simple String.Replace() call would suffice.

Anyway, if you want to use a regular expression, you must escape the ^, since it is a special character.

myString = Regex.Replace(myString, "\^+", String.Empty);
