Fields

ElementName

Name of the root element when object is serialized to XML.

Declaration
public const string ElementName = "REGEX"
Field Value

Properties

CultureInvariant

Gets or sets the flag indicating that cultural differences in language are ignored.

Declaration
public bool CultureInvariant { get; set; }
Property Value
Type Description
Boolean

ExplicitCapture

Gets or sets the flag indicating that the only valid captures are explicitly named or numbered groups of the form (?<name>…). This allows unnamed parentheses to act as noncapturing groups without the syntactic clumsiness of the expression (?:...).

Declaration
public bool ExplicitCapture { get; set; }
Property Value
Type Description
Boolean

IgnoreCase

Gets or sets the flag indicating case-insensitive matching.

Declaration
public bool IgnoreCase { get; set; }
Property Value
Type Description
Boolean

IgnoreWhitespace

Gets or sets the flag that eliminates unescaped white space from the pattern and enables comments marked with #. However, the flag value does not affect or eliminate white space in character classes.

Declaration
public bool IgnoreWhitespace { get; set; }
Property Value
Type Description
Boolean

Multiline

Gets or sets the flag indicating multiline mode. Changes the meaning of ^ and $ so they match at the beginning and end, respectively, of any line, and not just the beginning and end of the entire string. Leaving this property to False changes the meaning of the dot (.) so it matches every character (instead of every character except \n).

Declaration
public bool Multiline { get; set; }
Property Value
Type Description
Boolean

Pattern

Gets or sets the regular expression pattern to be matched.

Declaration
public string Pattern { get; set; }
Property Value
Type Description
String

RightToLeft

Gets or sets the flag indicating that the search will be from right to left instead of from left to right.

Declaration
public bool RightToLeft { get; set; }
Property Value
Type Description
Boolean
