無法解析CSDL

我在C＃中使用CsdlReader來解析csdl。整個XML文件如下：無法解析CSDL

這是我的代碼：

CsdlReader.TryParse(schemaReaders, out edmModel, out edmErrors)

正如你所看到的。 Role是End的屬性。但是，似乎我無法解析該XML。並且我在edmErrors中有這樣的錯誤：

{MissingAttribute：元素'End'上不存在所需模式屬性'角色'。：（0，0）}

該消息告訴我Role丟失，但我確實在我的csdl中有。在Sandbox實體容器的AssociationSet

如果可能，請提供完整的XML文件。 – CodeFuller

@CodeFuller謝謝。按要求提供。 – Zhao

End元件確實錯過Role屬性：

<AssociationSet Name=\"Editions_CountryRegions_CountryRegions_Country_Region\" Association=\"Sandbox.Editions_CountryRegions_CountryRegions_Country_Region\"> 
    <End EntitySet=\"Editions\" /> 
    <End EntitySet=\"CountryRegions\" /> 
    <bi:AssociationSet State=\"Inactive\" /> 
</AssociationSet>

這是解析錯誤的根本原因。

但我想知道這是怎麼發生的。 CSDL XML文件由Microsoft AS自動生成。爲什麼這個是不合格的？ – Zhao

它是根據OData版本。較早的版本生成沒有角色的AssociationSet，較新版本的CsdlReader期望角色在那裏。當前是4.0（見http://www.odata.org/documentation/）。

您可以通過查看程序集的屬性來查看CSDL的版本。如果您使用GetSchemaDataSet獲取了XML，則可以在RestrictionList參數中請求正確的版本。這隻在XMLA中顯示，但參數相同。（https://docs.microsoft.com/en-us/sql/analysis-services/schema-rowsets/xml/discover-csdl-metadata-rowset）
