Gets the options that were passed into the Regex constructor.

Namespace:  System.Text.RegularExpressions
Assemblies:   System.Text.RegularExpressions (in System.Text.RegularExpressions.dll)
  System (in System.dll)

public RegexOptions Options { get; }

Property Value

Type: System.Text.RegularExpressions.RegexOptions
One or more members of the RegexOptions enumeration that represent options that were passed to the Regex constructor

The value of the Options 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.

Note that the Options property does not reflect inline options defined in the regular expression pattern itself.

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 Options property. If called from a derived class, the Options property returns the options that were passed to the options parameter of the RegexCompilationInfo class constructor that was used to define the regular expression.
