SocketPermission::ConnectList Property

 

Gets a list of EndpointPermission instances that identifies the endpoints that can be connected to under this permission instance.

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

public:
property IEnumerator^ ConnectList {
	IEnumerator^ get();
}

Property Value

Type: System.Collections::IEnumerator^

An instance that implements the IEnumerator interface that contains EndpointPermission instances.

The following example uses the ConnectList property to return a list of endpoints to which connection privileges are granted.

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

// Create a 'SocketPermission' Object* for two ip addresses.
SocketPermission^ socketPermission2 = gcnew SocketPermission( PermissionState::None );
SecurityElement^ securityElement4 = socketPermission2->ToXml();

// 'SocketPermission' Object* for 'Connect' permission
SecurityElement^ securityElement1 = 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^ 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.
SecurityElement^ securityElement3 = gcnew SecurityElement( "URI","192.168.144.240#-1#3" );
securityElement1->AddChild( securityElement2 );
securityElement1->AddChild( securityElement3 );
securityElement4->AddChild( securityElement1 );

// Obtain a 'SocketPermission' Object* using 'FromXml' method.
socketPermission2->FromXml( securityElement4 );

// 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( "\nChecks the Socket permissions using IsUnrestricted method : " );
if ( socketPermission1->IsUnrestricted() )
      Console::WriteLine( "Socket permission is unrestricted" );
else
      Console::WriteLine( "Socket permission is restricted" );

Console::WriteLine();
Console::WriteLine( "Display result of ConnectList property : \n" );
IEnumerator^ enumerator = socketPermission3->ConnectList;
while ( enumerator->MoveNext() )
{
   Console::WriteLine( "The hostname is       : {0}", dynamic_cast<EndpointPermission^>(enumerator->Current)->Hostname );
   Console::WriteLine( "The port is           : {0}", dynamic_cast<EndpointPermission^>(enumerator->Current)->Port );
   Console::WriteLine( "The Transport type is : {0}", dynamic_cast<EndpointPermission^>(enumerator->Current)->Transport );
}

Console::WriteLine( "" );
Console::WriteLine( "Display Security Elements :\n " );
PrintSecurityElement( socketPermission2->ToXml(), 0 );

// Get a 'SocketPermission' Object* which is a union of two other 'SocketPermission' objects.
socketPermission1 = dynamic_cast<SocketPermission^>(socketPermission3->Union( socketPermission2 ));

// Demand that the calling method have the socket permission.
socketPermission1->Demand();
