This value should not be assigned to the System.Text.RegularExpressions.RegexCompilationInfo.Options property when calling the System.Text.RegularExpressions.Regex.CompileToAssembly() method. For more information, see the "Compiled Regular Expressions" section in the Regular Expression Options article.
System.Text.RegularExpressions.RegexOptions.CultureInvariant
Specifies that cultural differences in language is ignored. For more information, see the "Comparison Using the Invariant Culture" section in the Regular Expression Options article.
System.Text.RegularExpressions.RegexOptions.ECMAScript
Enables ECMAScript-compliant behavior for the expression. This value can be used only in conjunction with the System.Text.RegularExpressions.RegexOptions.IgnoreCase, System.Text.RegularExpressions.RegexOptions.Multiline, and System.Text.RegularExpressions.RegexOptions.Compiled values. The use of this value with any other values results in an exception.

System.Text.RegularExpressions.RegexOptions.ExplicitCapture
Specifies that the only valid captures are explicitly named or numbered groups of the form (?<name>...).

For more information, see the "Explicit Captures Only" section in the Regular Expression Options article.
System.Text.RegularExpressions.RegexOptions.IgnoreCase
Specifies case-insensitive matching. For more information, see the "Case-Insensitive Matching " section in the Regular Expression Options article.
System.Text.RegularExpressions.RegexOptions.IgnorePatternWhitespace
Eliminates unescaped white space from the pattern and enables comments marked with #. However, this value does not affect or eliminate white space in character classes, numeric quantifiers, or tokens that mark the beginning of individual regular expression language elements. For more information, see the "Ignore White Space" section of the Regular Expression Options article.
System.Text.RegularExpressions.RegexOptions.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. For more information, see the "Multiline Mode" section in the Regular Expression Options article.
System.Text.RegularExpressions.RegexOptions.NonBacktracking
Enable matching using an approach that avoids backtracking and guarantees linear-time processing in the length of the input.
System.Text.RegularExpressions.RegexOptions.None
Specifies that no options are set. For more information about the default behavior of the regular expression engine, see the "Default Options" section in the Regular Expression Options article.
System.Text.RegularExpressions.RegexOptions.RightToLeft
Specifies that the search will be from right to left instead of from left to right. For more information, see the "Right-to-Left Mode" section in the Regular Expression Options article.
System.Text.RegularExpressions.RegexOptions.Singleline
Specifies single-line mode. Changes the meaning of the dot (.) so it matches every character (instead of every character except \n). For more information, see the "Single-line Mode" section in the Regular Expression Options article.
