SocketPermission コンストラクタ (NetworkAccess, TransportType, String, Int32)
アセンブリ: System (system.dll 内)

Public Sub New ( _ access As NetworkAccess, _ transport As TransportType, _ hostName As String, _ portNumber As Integer _ )
Dim access As NetworkAccess Dim transport As TransportType Dim hostName As String Dim portNumber As Integer Dim instance As New SocketPermission(access, transport, hostName, portNumber)
public SocketPermission ( NetworkAccess access, TransportType transport, string hostName, int portNumber )
public: SocketPermission ( NetworkAccess access, TransportType transport, String^ hostName, int portNumber )
public SocketPermission ( NetworkAccess access, TransportType transport, String hostName, int portNumber )
public function SocketPermission ( access : NetworkAccess, transport : TransportType, hostName : String, portNumber : int )


このコンストラクタは、指定した transport を使用して指定した hostName と portNumber へのアクセスを制御する SocketPermission を作成します。
hostName は、DNS 名、IP アドレス、または 192.168.1.* などのように指定する IP サブネットにすることができます。
portNumber は、トランスポートが定義する任意の有効なポート番号または SocketPermission.AllPorts にすることができます。

NetworkAccess 列挙値、TransportType 列挙値、ホスト名、およびポート番号を使用して、SocketPermission を作成する例を次に示します。

SocketPermission コンストラクタ (PermissionState)
アセンブリ: System (system.dll 内)

public SocketPermission ( PermissionState state )
public: SocketPermission ( PermissionState state )
public SocketPermission ( PermissionState state )
public function SocketPermission ( state : PermissionState )

SocketPermission インスタンスが PermissionState の Unrestricted 値で作成された場合、SocketPermission インスタンスはすべての要求を渡します。トランスポート アドレスのアクセス許可に AddPermission が追加されていない限り、state のその他のすべての値では、すべての要求を失敗させる SocketPermission インスタンスが作成されます。
