ManagementScope.Connect メソッド

ManagementScope を実際の WMI スコープに接続します。

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

Visual Basic (宣言)

Public Sub Connect

Visual Basic (使用法)

Dim instance As ManagementScope

instance.Connect

public void Connect ()

C++

public:
void Connect ()

public void Connect ()

JScript

public function Connect ()

解説

このメソッドは、接続する必要がある操作でスコープが使用される場合、暗黙的に呼び出されます。接続時間を制御する場合は、このメソッドを明示的に呼び出します。

.NET Framework のセキュリティ

直前の呼び出し元に対する完全な信頼。このメンバは、信頼性が一部しか確認されていないコードでは使用できません。詳細については、「部分信頼コードからのライブラリの使用」を参照してください。

使用例

特定のパスを使用して新しい ManagementScope を初期化し、スコープオブジェクトを WMI 名前空間に接続する例を次に示します。この例では、リモートコンピュータ上の名前空間に接続します。
