設定 GetProperties 方法的項目命名空間
您可以使用 Reporting Services 中的 ItemNamespaceHeader SOAP 標頭,根據兩個不同的項目識別碼來擷取項目屬性:項目的完整路徑或是項目的識別碼。
當您呼叫 GetProperties 方法時,通常會以引數傳遞您要擷取屬性的項目之完整路徑。 您可以透過使用 ItemNamespaceHeader,傳遞項目的識別碼做為識別碼,為方法呼叫設定 SOAP 標頭,以便使用 GetProperties。
下列程式碼範例會根據項目的識別碼來擷取項目屬性值。
[!附註]
依預設,如果您以項目識別碼傳遞完整路徑名稱給 GetProperties 方法,則不需要為 ItemNamespaceHeader 設定值。
