在c#中使用xsd gen进行XML反序列化失败
本文关键字：进行 XML 反序列化 失败 gen xsd | 更新日期: 2023-09-27 18:10:37
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>

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.
