Members

Member name Description
Compiled Specifies that the regular expression is compiled to an assembly. This yields faster execution but increases startup time. This value should not be assigned to the Options property when calling the CompileToAssembly method.
CultureInvariant Specifies that cultural differences in language is ignored.
ECMAScript Enables ECMAScript-compliant behavior for the expression. This value can be used only in conjunction with the IgnoreCase, Multiline, and Compiled values. The use of this value with any other values results in an exception.
ExplicitCapture Specifies 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 (?:…).
IgnoreCase Specifies case-insensitive matching.
IgnorePatternWhitespace Eliminates unescaped white space from the pattern and enables comments marked with #.
Multiline 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.
None Specifies that no options are set.
Singleline Specifies single-line mode. Changes the meaning of the dot (.) so it matches every character (instead of every character except \n).
