Declaratively instructs the .NET Framework to perform string validation on a configuration property using a regular expression. This class cannot be inherited.
Assembly: System.Configuration (in System.Configuration.dll)
Thetype exposes the following members.
|Regex||Gets the string used to perform regular-expression validation.|
|TypeId||When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)|
|ValidatorInstance||Gets an instance of the RegexStringValidator class. (Overrides ConfigurationValidatorAttribute.ValidatorInstance.)|
|ValidatorType||Gets the type of the validator attribute. (Inherited from ConfigurationValidatorAttribute.)|
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from Attribute.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|IsDefaultAttribute||When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)|
|Match||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|_Attribute.GetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_Attribute.GetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_Attribute.GetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_Attribute.Invoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
You use the to decorate a configuration property, which will instruct the .NET Framework to validate the property using the RegexStringValidator and pass to it the value of the decorating parameters.
You may apply objects to property types only.
The following example shows how to decorate the properties of a custom ConfigurationSection object using the object.

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
