Thetype exposes the following members.
|Access||Gets or sets the network access method that is allowed by this .|
|Action||Gets or sets a security action. (Inherited from SecurityAttribute.)|
|Host||Gets or sets the DNS host name or IP address that is specified by this .|
|Port||Gets or sets the port number that is associated with this .|
|Transport||Gets or sets the TransportType that is specified by this .|
|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 SocketPermission class. (Overrides SecurityAttribute.CreatePermission.)|
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|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.)|
|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.)|
To use this attribute, your Socket connection must conform to the properties that are specified in your . For example, to apply the permission to a Socket connection on port 80, set the Port property of the to "80". The security information that is specified in is stored in the metadata of the attribute target, which is the class to which the is applied. The system then accesses the information at run time. The SecurityAction that is passed to the constructor determines the allowable targets.
The properties of a must have values that are not Nothing. Also, once set, the values of the properties cannot be changed.
