Thetype exposes the following members.
|Accept||Gets or sets the URI string accepted by the current .|
|AcceptPattern||Gets or sets a regular expression pattern that describes the URI accepted by the current .|
|Action||Gets or sets a security action. (Inherited from SecurityAttribute.)|
|Connect||Gets or sets the URI connection string controlled by the current .|
|ConnectPattern||Gets or sets a regular expression pattern that describes the URI connection controlled by the current .|
|TypeId||When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)|
|Unrestricted||Gets or sets a value indicating whether full (unrestricted) permission to the resource protected by the attribute is declared. (Inherited from SecurityAttribute.)|
|CreatePermission||Creates and returns a new instance of the WebPermission class. (Overrides SecurityAttribute.CreatePermission().)|
|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.)|
allows you to declaratively specify which URI strings and regular expression strings your class can use.
The security information specified in the is stored in the metadata of the attribute target, which is the class to which is applied. The system accesses this information at run time. The System.Security.Permissions.SecurityAction passed to the constructor determines the allowable targets. The system uses the WebPermission returned by the CreatePermission method to convert the security information of the attribute target to a serializable form stored in metadata.
