从使用 XSD.exe 生成的 XML 中反序列化类
我有从 .xsd 生成的类(使用 xsd.exe),我可以很好地序列化它,但是当我尝试反序列化它时,我收到错误:
{"<XMLLanguages xmlns='http://tempuri.org/XMLLanguages.xsd'> was not expected."}
我搜索了几个小时,发现大多数人的问题在于不在其 xsd/xml 中声明名称空间,不在其类中定义名称空间等,但我找不到解决问题的方法。
以下是相关类的代码片段。
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="XMLLanguages"
targetNamespace="http://tempuri.org/XMLLanguages.xsd"
elementFormDefault="qualified"
xmlns="http://tempuri.org/XMLLanguages.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
>
<xs:element name="XMLLanguages">
<xs:complexType>
<xs:sequence>
<xs:element name="Tier" minOccurs="1" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="L" minOccurs="1" maxOccurs="unbounded" type="Language"/>
</xs:sequence>
<xs:attribute name="TierID" type="xs:int"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="Language">
<xs:sequence>
<xs:element name="LangID" type="xs:int"/>
<xs:element name="Tier" type="xs:int"/>
<xs:element name ="Name" type="xs:string"/>
</xs:sequence>
<xs:attribute name ="PassRate" type="xs:int"/>
</xs:complexType>
</xs:schema>
类:
/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.1")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://tempuri.org/XMLLanguages.xsd")]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://tempuri.org/XMLLanguages.xsd", IsNullable = false)]
public partial class XMLLanguages
{
private List<XMLLanguagesTier> tierField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("Tier")]
public List<XMLLanguagesTier> Tiers {
get {
return this.tierField;
}
set {
this.tierField = value;
}
}
}
以及 XML 中导致错误的行:
<XMLLanguages xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/XMLLanguages.xsd">
反序列化方法:
public static object Deserialize(XmlDocument xml, Type type)
{
XmlSerializer s = new XmlSerializer(type);
string xmlString = xml.OuterXml.ToString();
byte[] buffer = ASCIIEncoding.UTF8.GetBytes(xmlString);
MemoryStream ms = new MemoryStream(buffer);
XmlReader reader = new XmlTextReader(ms);
Exception caught = null;
try
{
object o = s.Deserialize(reader);
return o;
}
catch (Exception e)
{
caught = e;
}
finally
{
reader.Close();
if (caught != null)
throw caught;
}
return null;
}
I have classes generated (using xsd.exe) from an .xsd that I can serialize just fine, but when I try and deserialize it, I get the error:
{"<XMLLanguages xmlns='http://tempuri.org/XMLLanguages.xsd'> was not expected."}
I've searched for a couple of hours and found most peoples problems lie in not declaring namespaces in their xsd/xml, not defining namespaces in their classes, etc, but I can't find a solution for my problem.
Here are code snippets for the relevant classes.
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="XMLLanguages"
targetNamespace="http://tempuri.org/XMLLanguages.xsd"
elementFormDefault="qualified"
xmlns="http://tempuri.org/XMLLanguages.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
>
<xs:element name="XMLLanguages">
<xs:complexType>
<xs:sequence>
<xs:element name="Tier" minOccurs="1" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="L" minOccurs="1" maxOccurs="unbounded" type="Language"/>
</xs:sequence>
<xs:attribute name="TierID" type="xs:int"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:complexType name="Language">
<xs:sequence>
<xs:element name="LangID" type="xs:int"/>
<xs:element name="Tier" type="xs:int"/>
<xs:element name ="Name" type="xs:string"/>
</xs:sequence>
<xs:attribute name ="PassRate" type="xs:int"/>
</xs:complexType>
</xs:schema>
And the class:
/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.1")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://tempuri.org/XMLLanguages.xsd")]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://tempuri.org/XMLLanguages.xsd", IsNullable = false)]
public partial class XMLLanguages
{
private List<XMLLanguagesTier> tierField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("Tier")]
public List<XMLLanguagesTier> Tiers {
get {
return this.tierField;
}
set {
this.tierField = value;
}
}
}
And a the line in XML causing the error:
<XMLLanguages xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/XMLLanguages.xsd">
Deserializing method:
public static object Deserialize(XmlDocument xml, Type type)
{
XmlSerializer s = new XmlSerializer(type);
string xmlString = xml.OuterXml.ToString();
byte[] buffer = ASCIIEncoding.UTF8.GetBytes(xmlString);
MemoryStream ms = new MemoryStream(buffer);
XmlReader reader = new XmlTextReader(ms);
Exception caught = null;
try
{
object o = s.Deserialize(reader);
return o;
}
catch (Exception e)
{
caught = e;
}
finally
{
reader.Close();
if (caught != null)
throw caught;
}
return null;
}

我使用下面的代码并且工作正常。
我将 xsd.exe 与 /n:xyz 命名空间选项一起使用。
这似乎工作正常,所以我认为您的问题一定是 tempuri.org 域名。
希望这对您有所帮助。

I use the following code and it works fine.
I use xsd.exe with the /n:xyz namespace option.
This seems to work fine, so I assume your problem must be with the tempuri.org domain name.
Hope this is of some help.

您需要从根中删除 targetNamespace 属性,并在 XMLLanguages 节点之前添加以下节点:
上面将允许您反序列化,但我感觉到即将出现其他问题。您面临的问题是,当您定义多个复杂类型时,您不能使用 targetNamespace 属性 - 欢迎来到模式命名空间地狱......
You need to remove the targetNamespace attribute from the root, and add the following node before the XMLLanguages node:
The above will let you deserialize, but I sense other problems on the horizon. The problem you were facing was that when you define multiple complex types, you can't use the targetNamespace attribute -- welcome to schema namespace hell...
