備註
組態設定會儲存在組態檔的階層中。 類別 Configuration 實例代表套用至特定實體實體的所有組態檔組態設定的合併檢視，例如計算機或邏輯實體，例如應用程式或網站。 邏輯實體可以存在於本機電腦或遠端伺服器上。 如需配置檔的相關信息，請參閱 設定應用程式和ASP.NET 組態檔。
當指定的實體沒有組態檔存在時， Configuration 物件代表由 Machine.config 檔案所定義的預設組態設定。
您可以使用下列類別來取得 Configuration 物件：
如果您的實體是用戶端應用程式，則 ConfigurationManager 為類別。
如果您的實體是 Web 應用程式，則為 類別 WebConfigurationManager 。
傳回 Configuration 物件的方法名稱開頭為 「Open」。
您也可以產生組態檔，代表 物件中的 Configuration 組態設定。 若要執行此工作，請使用下列的其中一個方法：
建立組態檔的方法名稱開頭為 「Save」。
注意
若要啟用遠端電腦上的組態設定存取權，請使用 Aspnet_regiis 命令行工具。 如您要此工具的詳細資訊，請參閱 ASP.NET IIS 註冊工具 (Aspnet_regiis.exe) 。 如需建立及存取 .NET Framework 中所含內建區段以外的自定義組態設定的相關信息，請參閱 ConfigurationSection。
給繼承者的注意事項
類別 Configuration 提供編輯組態檔的程式設計存取。 您可以使用 Web 應用程式的 類別所提供的 WebConfigurationManager 其中一個「Open」方法，或由用戶端應用程式的 ConfigurationManager 類別提供。 這些方法會傳回 Configuration 物件，接著會提供處理基礎組態檔的方法和屬性。 您可以存取這些檔案來讀取或寫入組態資訊。
您可以使用 GetSection(String) 方法或 GetSectionGroup(String) 方法來讀取組態資訊。 請注意，讀取的使用者或進程必須具有下列許可權：
目前組態階層層級之組態檔的讀取許可權。
所有父組態檔的讀取許可權。
如果您的應用程式需要本身設定的唯讀存取權，建議您針對 Web 應用程式使用 GetSection 方法多載。 針對用戶端應用程式，請使用 GetSection(String) 方法。
這些方法提供目前應用程式的快取組態值存取權，其效能優於 Configuration 類別。
注意：如果您使用採用path參數的靜態 GetSection 方法，path 參數必須參考執行程式碼的應用程式，否則會忽略 參數，並傳回目前執行中應用程式的組態資訊。
您可以使用其中 Save 一種方法來撰寫組態資訊。 請注意，寫入的使用者或進程必須具有下列許可權：
目前組態階層層級之組態檔和目錄的寫入許可權。
所有組態檔的讀取許可權。
屬性
