如何在XElement上放置名称空间别名?如何将数据源添加到现有的RDL文档

Question

我试图创建一个数据源的XElement以插入到SSRS RDL文件中。但是，我似乎无法让它正确地创建rd:别名。这是我正在使用的代码。

XNamespace rootNs = "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition";
XNamespace rdNs = "http://schemas.microsoft.com/SQLServer/reporting/reportdesigner";
XElement _dataSource = new XElement("DataSource",                            
             new XAttribute(XNamespace.Xmlns + "rd", rdNs),
             new XAttribute("Name", "eFinancials_LOCAL"),
             new XElement("ConnectionProperties", new XElement("DataProvider", "SQL"), new XElement("ConnectString", connectionString)),
             new XElement(_rdns + "SecurityType", "DataBase"),
             new XElement(_rdns + "DataSourceID", dataSourceId)
                                            );

生成的XML元素是:

<DataSource xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner" Name="eFinancials_LOCAL">
  <ConnectionProperties>
    <DataProvider>SQL</DataProvider>
    <ConnectString>Data Source=.;Initial Catalog=800_LMS_eFin_Deploy</ConnectString>
  </ConnectionProperties>
  <SecurityType xmlns="rd">DataBase</SecurityType>
  <DataSourceID xmlns="rd">56e5e869-6ca5-44f9-8340-22821177569e</DataSourceID>
</DataSource>

但是，它必须是:

<DataSource Name="eFinancials_LOCAL">
  <ConnectionProperties>
    <DataProvider>SQL</DataProvider>
    <ConnectString>Data Source=.;Initial Catalog=800_LMS_eFin_Deploy</ConnectString>
  </ConnectionProperties>
  <rd:SecurityType>DataBase</SecurityType>
  <rd:DataSourceID>56e5e869-6ca5-44f9-8340-22821177569e</DataSourceID>
</DataSource>

我如何调整我的代码来创建正确的XML如上所述?我几乎要把它创建为文本了

XNamespace ns = @"http://www.somesite.com/xml/customer/2006-10-31";
XElement xe = new XElement(ns + "customers", 
   new XAttribute("xmlns", ns),
   new XElement(ns + "customer", new XElement(ns + "firstname", customer.FirstName);
