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

Syntax

'Declaration
Public Sub New ( _
    pattern As String, _
    matchFlags As RegexOptions _
)

public Regex(
    string pattern,
    RegexOptions matchFlags
)

public:
Regex(
    String^ pattern, 
    RegexOptions matchFlags
)

new : 
        pattern:string * 
        matchFlags:RegexOptions -> Regex

public function Regex(
    pattern : String, 
    matchFlags : RegexOptions
)

Parameters

• pattern
  Type: System. . :: . .String
  The regular expression pattern to match.

• matchFlags
  Type: System.Text.RegularExpressions. . :: . .RegexOptions
  A bitwise combination of the enumeration values that modify the regular expression.

Remarks

The pattern parameter consists of regular expression language elements that symbolically describe the string to match.

A Regex object is immutable, which means that it can be used only for the match parameters you define when you create it. However, it can be used any number of times without being recompiled.
