名前空間: System.Net
アセンブリ: System (system.dll 内)
構文
'宣言
Public Sub New ( _
token As String, _
finished As Boolean _
)
'使用
Dim token As String
Dim finished As Boolean
Dim instance As New Authorization(token, finished)
public Authorization (
string token,
bool finished
)
public:
Authorization (
String^ token,
bool finished
)
public Authorization (
String token,
boolean finished
)
public function Authorization (
token : String,
finished : boolean
)
パラメータ
- token
サーバーが受信する暗号化された承認メッセージ。
- finished
承認試行の完了ステータス。承認試行が完了した場合は true。それ以外の場合は false。
解説
Authorization インスタンスは、Message プロパティを token に設定し、Complete プロパティを finished に設定して作成します。
使用例
指定した承認メッセージおよび承認の完了ステータスを使用して、Authorization クラスの新しいインスタンスを作成するコード例を次に示します。
