使用替换组反序列化消息时出现问题
我有以下使用 XmlSerializer 反序列化的 XML 消息。 由于某些原因,该消息的反序列化会剥离 XML 消息的数据库部分。 我需要一些帮助来完整地反序列化此消息。
这是一个示例测试 XML 消息。
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<Radars xmlns="http://mycompany.com/2008/c2s2">
<Radar>
<Identification>
<Identifier>140:141</Identifier>
<IP>10.216.1.79</IP>
<Label>Radar 1</Label>
<Model>Radar123</Model>
<Category>Civil</Category>
</Identification>
<Database>
<Radar456General>
<Identifier>203</Identifier>
<Version>8</Version>
<RadarStartStop>false</RadarStartStop>
<AntennaRotationSpeed>false</AntennaRotationSpeed>
<RadarAntennaRotation>false</RadarAntennaRotation>
<AntennaStaringPosition>0</AntennaStaringPosition>
</Radar456General>
</Database>
</Radar>
</Radars>
我正在使用 XmlSerializer 反序列化上述消息,如下所示:
public static T Deserialize<T>(string message)
{
object obj = null;
try
{
XmlSerializer xs = new XmlSerializer(typeof(T));
StringReader reader = new StringReader(message);
XmlTextReader xmlReader = new XmlTextReader(reader);
obj = xs.Deserialize(xmlReader);
xmlReader.Close();
reader.Close();
}
catch (Exception ex)
{
Console.WriteLine(ex);
throw ex;
}
return (T)obj;
}
Radars Radars = Serializer.Deserialize
反序列化后,我得到一个空的数据库部分(即 Radars.radar[0] .数据库.长度== 0)。
消息的架构在单独的 XSD 文件中指定。我使用 xsd.exe 从中生成 C# 类。 这是XSD文件的部分内容。

那么如何使用数据库部分反序列化消息呢?
I have the following XML message that I deserialize with XmlSerializer.
For some reasons, deserialization of this message strips the Database section of the XML message.
I need some help in deserializing this message in its entirety.
This is a sample test XML message.
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<Radars xmlns="http://mycompany.com/2008/c2s2">
<Radar>
<Identification>
<Identifier>140:141</Identifier>
<IP>10.216.1.79</IP>
<Label>Radar 1</Label>
<Model>Radar123</Model>
<Category>Civil</Category>
</Identification>
<Database>
<Radar456General>
<Identifier>203</Identifier>
<Version>8</Version>
<RadarStartStop>false</RadarStartStop>
<AntennaRotationSpeed>false</AntennaRotationSpeed>
<RadarAntennaRotation>false</RadarAntennaRotation>
<AntennaStaringPosition>0</AntennaStaringPosition>
</Radar456General>
</Database>
</Radar>
</Radars>
I am using XmlSerializer to deserialize the above message like this:
public static T Deserialize<T>(string message)
{
object obj = null;
try
{
XmlSerializer xs = new XmlSerializer(typeof(T));
StringReader reader = new StringReader(message);
XmlTextReader xmlReader = new XmlTextReader(reader);
obj = xs.Deserialize(xmlReader);
xmlReader.Close();
reader.Close();
}
catch (Exception ex)
{
Console.WriteLine(ex);
throw ex;
}
return (T)obj;
}
Radars radars = Serializer.Deserialize<Radars>(message);
After deserializing it, I get an empty Database section (meaning radars.radar[0].Database.Length == 0).
The schema of the message is specified in a separate XSD file. I use xsd.exe to generate C# classes from it.
This is the partial content of the XSD file.

So how can I deserialize the message with Database section?

尝试在代码中创建相同的对象结构,将其序列化并查看数据和序列化日期之间的差异,然后您就会知道出了什么问题。
Try create the same object structure in code, serialize it and see he differences between your data and serialized date, than you'll know whats wrong.
