SocketPermission.AddPermission メソッド

トランスポートアドレスのアクセス許可のセットにアクセス許可を追加します。

名前空間: System.Net
アセンブリ: System (system.dll 内)
構文

Visual Basic (宣言)

Public Sub AddPermission ( _
    access As NetworkAccess, _
    transport As TransportType, _
    hostName As String, _
    portNumber As Integer _
)

Visual Basic (使用法)

Dim instance As SocketPermission
Dim access As NetworkAccess
Dim transport As TransportType
Dim hostName As String
Dim portNumber As Integer

instance.AddPermission(access, transport, hostName, portNumber)

public void AddPermission (
    NetworkAccess access,
    TransportType transport,
    string hostName,
    int portNumber
)

C++

public:
void AddPermission (
    NetworkAccess access, 
    TransportType transport, 
    String^ hostName, 
    int portNumber
)

public void AddPermission (
    NetworkAccess access, 
    TransportType transport, 
    String hostName, 
    int portNumber
)

JScript

public function AddPermission (
    access : NetworkAccess, 
    transport : TransportType, 
    hostName : String, 
    portNumber : int
)

パラメータ

access: NetworkAccess 値の 1 つ。

transport: TransportType 値の 1 つ。

hostName: トランスポートアドレスのホスト名。

portNumber: トランスポートアドレスのポート番号。

解説

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。

使用例

AddPermission メソッドを使用して、指定したホストに接続許可を追加する例を次に示します。
