Defines the attribute that controls use to identify string properties containing URL values. This class cannot be inherited.

Thetype exposes the following members.
|Equals||Returns a value that indicates whether this instance is equal to a specified object. (Overrides Attribute::Equals(Object).)|
|GetHashCode||Returns the hash code for this instance. (Overrides Attribute::GetHashCode().)|
|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.)|
|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.)|
The attribute is an attribute applied to a control property that represents a URL. In addition to marking a string property as representing a URL, the attribute defines the Filter property that identifies specific file types that can be used to filter against the property.
The following code example demonstrates a class that implements a URL-specific property. In this code example, a attribute is applied to the TargetUrl property of the CustomHyperLinkControl class. The attribute sets a specific file filter for ASP.NET files.
