缺少显示xsd文件中表之间关系的链接
我已经学会了如何使用xsd.exe文件在XML文件上创建XSD文件。 现在我有一个site.xml文件和一个原理图文件site.xsd。我需要这个，因为我正在查看现有的应用程序，并试图了解它是如何工作的，所以必须从基本步骤开始。现在情况还可以，但我唯一的问题是，在site.xsd（原始应用程序）中，当我在VS2010中打开它时，它会显示两个表（就像我们在SQL SERVER和Access中一样），它显示主键和图形链接时的外键）我也会显示表格，但不会以图形方式链接它们。
在生成xsd文件时我错过了什么步骤？
感谢。

1 个答案:
答案 0 :(得分：1)
听起来你的问题与XSD推理引擎使用的“设计风格”有关。这是一个很受欢迎的问题，一段时间我回答here。
基本上，俄罗斯娃娃风格的XSD（就像你的情况下创建的那样）会产生一个缺少关系的数据集。此样式不使用全局或元素声明（根除外）。通过使global成为与根元素关联的类型，您的关系应该显示出来。
根据您更新的帖子：
这就是您的XSD作为数据集的样子：
修改为使用全局类型（类型T）：
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

它看起来如下。
看看你的XSD，你的问题可能会有所不同......也许你期望看到类别和产品之间的关系？基于CategoryID？
如果是这样，那么你需要使用Microsoft特定的标记;有关详细信息，请参阅this article，this。
