RegexRunnerFactory Class

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Creates a RegexRunner class for a compiled regular expression.

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

Public MustInherit Class RegexRunnerFactory
Dim instance As RegexRunnerFactory

A RegexRunner object executes a compiled regular expression. A regular expression that is compiled to an assembly becomes a type in that assembly, and an object of that type is typically created using reflection. However, creating an object by reflection is an expensive operation. The RegexRunnerFactory class improves the performance of the .NET Framework by providing the CreateInstance method, which creates a RegexRunner object for a specific compiled regular expression.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
