SocketPermissionAttribute Class

Specifies security actions to control Socket connections. This class cannot be inherited.

Namespace:  System.Net
Assembly:  System (in System.dll)

public final class SocketPermissionAttribute extends CodeAccessSecurityAttribute

To use this attribute, your Socket connection must conform to the properties that are specified in your SocketPermissionAttribute. For example, to apply the permission to a Socket connection on port 80, set the Port property of the SocketPermissionAttribute to "80". The security information that is specified in SocketPermissionAttribute is stored in the metadata of the attribute target, which is the class to which the SocketPermissionAttribute is applied. The system then accesses the information at run time. The SecurityAction that is passed to the constructor determines the allowable SocketPermissionAttribute targets.


The properties of a SocketPermissionAttribute must have values that are not a null reference (Nothing in Visual Basic). Also, once set, the values of the properties cannot be changed.
