Regex.IsMatch Method (String, String, RegexOptions)

Indicates whether the regular expression finds a match in the input string, using the regular expression specified in the pattern parameter and the matching options supplied in the options parameter.

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

public static bool IsMatch (
	string input,
	string pattern,
	RegexOptions options
public static boolean IsMatch (
	String input, 
	String pattern, 
	RegexOptions options
public static function IsMatch (
	input : String, 
	pattern : String, 
	options : RegexOptions
) : boolean



The string to search for a match.


The regular expression pattern to match.


A bitwise OR combination of RegexOption enumeration values.

Return Value

true if the regular expression finds a match; otherwise, false.

The two static IsMatch methods are equivalent to constructing a Regex object with the specified regular expression pattern and calling the instance method IsMatch. The static methods are provided to allow an isolated, single use of a regular expression without explicitly creating a Regex object.
