您好我如何使用C＃读取带有嵌套表的xml文件，并使用这样的向下钻取数据进行显示。我尝试了DataSet.ReadXml方法，但这些表是单独存储而没有关系。它们可以通过ds.Tables [1]，ds.Tables [2]访问。我希望能够显示关系，所以我可以显示如下数据。
ParentTable_Column1，ChildTable1_Column1，ChildTable2_Column1
这是架构

见下面的代码。我将所有数据放入一个表中，但您可以根据需要创建多个表并添加键，这样您就可以在表中使用公共字段。将所有数据放入一列没有任何问题，除了它将在数据库中使用更多空间。将公共数据拆分成表可以节省数据库中的空间。我将两列数据放入表中，因此您必须完成代码：
root.destroy
