The value of the property consists of one or more members of the RegexOptions enumeration. If no options were defined in the Regex class constructor, its value is RegexOptions.None. The available options are discussed in detail in the Regular Expression Options topic.Notes to Inheritors
Regex is the base class of regular expressions created by the CompileToAssembly method. These compiled regular expressions use the base class implementation of the property. If called from a derived class, the property returns the options that were passed to the options parameter of the RegexCompilationInfo class constructor that was used to define the regular expression.
