以程式設計方式存取 WMI 提供者
本主題尚在建構中。
WMI 提供者概觀
在本主題顯示的程式碼範例使用 System.Management 命名空間來取得有關 Reporting Services 的資訊，您可以在 Microsoft .NET Framework 中找到其相關資訊。 System.Management 命名空間提供一組 Managed 程式碼類別，.NET Framework 應用程式可以透過這些類別來存取和操作管理資訊。 如需有關使用 System.Management 命名空間以運用 Reporting Services WMI 類別的詳細資訊，請參閱 Microsoft .NET Framework SDK 中的＜使用 System.Managment 存取管理資訊＞。
尋找報表伺服器執行個體
在報表伺服器安裝上尋找資訊的最好方法，就是列舉 WMI 執行個體集合。 以下範例顯示如何建立集合，以及對集合執行迴圈以顯示屬性，來尋找每個報表伺服器執行個體上的屬性。

Dim scope As ManagementScope

'Connect to the Reporting Services namespace.
scope.Connect()
'Create the server class.
serverClass = New ManagementClass(WmiRSClass)
'Connect to the management object.
serverClass.Get()
If serverClass Is Nothing Then Throw New Exception("No class found")
'Loop through the instances of the server class.
