在c#中使用xsd gen进行XML反序列化失败

Question

我正在尝试反序列化XML文件。我使用xsd来生成结构。看起来文件没有被反序列化或其他东西，因为我在调试模式下将鼠标悬停在数据对象上时得到NULL值。对于这个问题的任何帮助都是非常感谢的。我希望能够循环遍历结构中的所有"功能块"。

包含数据的XML看起来像这样:

<?xml version="1.0" encoding="utf-8" ?>
<shapes>
  <FunctionalBlocks>
    <FunctionalBlock uid="{446C5C15-FF16-491D-910B-B8F9F4D90960}" name="1FT001">
      <props>
        <prop name="Typical or Mode" />
        <prop name="Function Template Type">MA</prop>
        <prop name="Node">01</prop>
        <prop name="System (Tag)">1</prop>
        <prop name="Instrumentation Identification (Tag)">FT</prop>
        <prop name="Sequence Number (Tag)">001</prop>
        <prop name="Comment">Production</prop>

我可以通过复制您的xml并执行EDIT -> Paste Special -> Paste xml作为类来完成此工作。你生成的类一定有问题。

使用这个新类定义，您必须确保在更改其名称时更改按钮单击事件以使用新类:

编辑

用上面的类，和反序列化代码稍微修改一下:

XmlSerializer serializer = new XmlSerializer(typeof(shapes), new XmlRootAttribute("shapes"));
FileStream fs = new FileStream("XMLFile1.xml", FileMode.Open);
XmlReader xtr = XmlReader.Create(fs);
shapes data = (shapes)serializer.Deserialize(xtr);
xtr.Close();

data现在包含一个类型为shapesFunctionalBlock的数组。您可以像这样访问它们:

shapesFunctionalBlock foo = data.FunctionalBlocks[0];
shapesFunctionalBlock foo2 = data.FunctionalBlocks[1];
//...etc.
