使用分析管理對象（AMO）將xmla文件反序列化爲對象

Question

我想將其中包含數據庫對象的xmla文件反序列化爲正確的對象表示形式。 （我不知道它是否應該是一個數據庫）。所以，我做到以下幾點：

Database db = new Database(); 
XmlTextReader xmlread = new XmlTextReader("input.xmla"); 
Microsoft.AnalysisServices.Utils.Deserialize(xmlread, db); 
xmlread.Close(); 

，但我得到了以下錯誤：

Unhandled Exception: Microsoft.AnalysisServices.XmlSerializationException: Unexpected root 'Create' (namespace 'http://schemas.microsoft.com/analysisservices/2003/engine') when trying to read 'Microsoft.AnalysisServices.Database'. 
    at Microsoft.AnalysisServices.DesignXmlReader.ReadRoot (System.Type type) [0x00000] in <filename unknown>:0 
    at Microsoft.AnalysisServices.DesignXmlReader.DeserializeComponent (IDesignerSerializationManager manager, System.Xml.XmlReader reader, System.Type root) [0x00000] in <filename unknown>:0 
    at Microsoft.AnalysisServices.JaXmlSerializer.DeserializeComponent (IDesignerSerializationManager manager, System.Xml.XmlReader reader, System.Type root) [0x00000] in <filename unknown>:0 
    at Microsoft.AnalysisServices.Utils.Deserialize (System.Xml.XmlReader xmlReader, Microsoft.AnalysisServices.MajorObject obj) [0x00000] in <filename unknown>:0 

的input.xmla文件看起來是這樣的：

<Create xmlns="http://schemas.microsoft.com/analysisservices/2003/engine"> 
    <ObjectDefinition> 
     <Database xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ddl2="http://schemas.microsoft.com/analysisservices/2003/engine/2" xmlns:ddl2_2="http://schemas.microsoft.com/analysisservices/2003/engine/2/2" xmlns:ddl100_100="http://schemas.microsoft.com/analysisservices/2008/engine/100/100" xmlns:ddl200="http://schemas.microsoft.com/analysisservices/2010/engine/200" xmlns:ddl200_200="http://schemas.microsoft.com/analysisservices/2010/engine/200/200"> 
      <ID>100</ID> 
      <Name>Deserialized</Name> 
      <Description>Deserialized Description</Description> 
     </Database> 
    </ObjectDefinition> 
</Create> 

我找不到很好的例子。任何幫助將不勝感激。

問題是，您試圖反序列化包含「CREATE」命令的xmla文檔，而不是序列化的數據庫對象。如果您只有一個xml閱讀器，只能坐在數據庫節點上，它應該可以工作！
