Regex.Escape Method

Escapes a minimal set of metacharacters (\, *, +, ?, |, {, [, (,), ^, $,., #, and white space) by replacing them with their escape codes.

Namespace: System.Text.RegularExpressions
Assembly: System (in system.dll)

public static function Escape (
	str : String
) : String



The input string containing the text to convert.

Return Value

A string of characters with any metacharacters converted to their escaped form.

Escape converts a string so it can be used as a constant within a regular expression. (The number sign (#) and white-space characters must be escaped so the string can be used within an expression parsed with the IgnorePatternWhitespace option enabled. If future.NET regular expression features add additional metacharacters, Escape converts those characters to escaped form as well.)
