SocketPermission.IsUnrestricted Method

Checks the overall permission state of the object.

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

public:
virtual bool IsUnrestricted () sealed
public final boolean IsUnrestricted ()
public final function IsUnrestricted () : boolean
Not applicable.

Return Value

true if the SocketPermission instance is created with the Unrestricted value from PermissionState; otherwise, false.

The following example checks the IsUnrestricted property to determine if the specified SocketPermission has any restrictions.

SocketPermission^ socketPermission1 = gcnew SocketPermission( PermissionState::Unrestricted );

// Create a 'SocketPermission' Object* for two ip addresses.
SocketPermission^ socketPermission2 = gcnew SocketPermission( PermissionState::None );

// Format to specify ip address are <ip-address>#<port>#<transport-type>
// First 'SocketPermission' ip-address is '192.168.144.238' for 'All' transport types and for 'All' ports for the ip-address.
SecurityElement^ securityElement2 = gcnew SecurityElement( "URI","192.168.144.238#-1#3" );

// Second 'SocketPermission' ip-address is '192.168.144.240' for 'All' transport types and for 'All' ports for the ip-address.
