SocketPermission::AllPorts Field
.NET Framework (current version)
Defines a constant that represents all ports.
Assembly: System (in System.dll)
This field is read-only. The value of this field is -1.
The following example uses the AllPorts property to provide connection permissions to all of the resources ports.
SocketPermission^ socketPermission1 = gcnew SocketPermission( PermissionState::Unrestricted ); // Create a 'SocketPermission' Object* for two ip addresses. SocketPermission^ socketPermission2 = gcnew SocketPermission( PermissionState::None ); SecurityElement^ securityElement1 = socketPermission2->ToXml(); // 'SocketPermission' Object* for 'Connect' permission SecurityElement^ securityElement2 = gcnew SecurityElement( "ConnectAccess" ); // 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^ securityElement3 = 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. SecurityElement^ securityElement4 = gcnew SecurityElement( "URI","192.168.144.240#-1#3" ); securityElement2->AddChild( securityElement3 ); securityElement2->AddChild( securityElement4 ); securityElement1->AddChild( securityElement2 ); // Obtain a 'SocketPermission' Object* using 'FromXml' method. socketPermission2->FromXml( securityElement1 ); Console::WriteLine( "\nDisplays the result of FromXml method : \n" ); Console::WriteLine( socketPermission2 ); // Create another 'SocketPermission' Object* with two ip addresses. // First 'SocketPermission' ip-address is '192.168.144.238' for 'All' transport types and for 'All' ports for the ip-address. SocketPermission^ socketPermission3 = gcnew SocketPermission( NetworkAccess::Connect, TransportType::All, "192.168.144.238", SocketPermission::AllPorts ); // Second 'SocketPermission' ip-address is '192.168.144.239' for 'All' transport types and for 'All' ports for the ip-address. socketPermission3->AddPermission( NetworkAccess::Connect, TransportType::All, "192.168.144.239", SocketPermission::AllPorts ); Console::WriteLine( "Displays the result of AddPermission method : \n" ); Console::WriteLine( socketPermission3 ); // Find the intersection between two 'SocketPermission' objects. socketPermission1 = dynamic_cast<SocketPermission^>(socketPermission2->Intersect( socketPermission3 )); Console::WriteLine( "Displays the result of Intersect method :\n " ); Console::WriteLine( socketPermission1 ); // Demand that the calling method have the requsite socket permission. socketPermission1->Demand();
