Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

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.

Note

The properties of a SocketPermissionAttribute must have values that are not null. Also, once set, the values of the properties cannot be changed.

Note

Constructors

SocketPermissionAttribute(SecurityAction)

Initializes a new instance of the SocketPermissionAttribute class with the specified SecurityAction value.

Properties

Access	Gets or sets the network access method that is allowed by this SocketPermissionAttribute.
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 SocketPermissionAttribute.
Port	Gets or sets the port number that is associated with this SocketPermissionAttribute.
Transport	Gets or sets the TransportType that is specified by this SocketPermissionAttribute.
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)

Methods

CreatePermission()	Creates and returns a new instance of the SocketPermission class.
Equals(Object)	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(Object)	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)
