由于命名空间,反序列化 xml 失败
Failed deserializing xml due to namespaces
我有以下 xml 我想反序列化为 c# class:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://www.s1.com/info/" xmlns:types="http://www.s1.com/info/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header>
<tns:SessionInfo>
<SessionId xsi:type="xsd:string">string</SessionId>
</tns:SessionInfo>
</soap:Header>
<soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<tns:LoginResponse>
<Result xsi:type="xsd:boolean">boolean</Result>
</tns:LoginResponse>
</soap:Body>
</soap:Envelope>
我正在使用以下 classes 来反序列化 xml:
public class SessionId
{
[XmlAttribute(AttributeName = "type", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
public string Type { get; set; }
[XmlText]
public string Text { get; set; }
}
[XmlRoot(ElementName = "SessionInfo", Namespace = "http://www.s1.com/info/")]
public class SessionInfo
{
[XmlElement(ElementName = "SessionId")]
public SessionId SessionId { get; set; }
[XmlAttribute(AttributeName = "id", Namespace = "")]
public string Id { get; set; }
[XmlText]
public string Text { get; set; }
}
[XmlRoot(ElementName = "Header", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
public class Header
{
[XmlElement(ElementName = "SessionInfo", Namespace = "http://www.s1.com/info/")]
public SessionInfo SessionInfo { get; set; }
}
[XmlRoot(ElementName = "Result", Namespace = "")]
public class Result
{
[XmlAttribute(AttributeName = "type", Namespace = "http://www.w3.org/2001/XMLSchema-instance")]
public string Type { get; set; }
[XmlText]
public string Text { get; set; }
}
[XmlRoot(ElementName = "LoginResponse", Namespace = "http://www.s1.com/info/")]
public class LoginResponse
{
[XmlElement(ElementName = "Result")]
public Result Result { get; set; }
}
[XmlRoot(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
public class Body
{
[XmlElement(ElementName = "LoginResponse", Namespace = "http://www.s1.com/info/")]
public LoginResponse LoginResponse { get; set; }
[XmlAttribute(AttributeName = "encodingStyle", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
public string EncodingStyle { get; set; }
[XmlText]
public string Text { get; set; }
}
[XmlRoot(ElementName = "Envelope", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
public class Envelope
{
[XmlElement(ElementName = "Header", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
public Header Header { get; set; }
[XmlElement(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
public Body Body { get; set; }
[XmlAttribute(AttributeName = "xsi", Namespace = "http://www.w3.org/2000/xmlns/")]
public string Xsi { get; set; }
[XmlAttribute(AttributeName = "xsd", Namespace = "http://www.w3.org/2000/xmlns/")]
public string Xsd { get; set; }
[XmlAttribute(AttributeName = "soapenc", Namespace = "http://www.w3.org/2000/xmlns/")]
public string Soapenc { get; set; }
[XmlAttribute(AttributeName = "tns", Namespace = "http://www.w3.org/2000/xmlns/")]
public string Tns { get; set; }
[XmlAttribute(AttributeName = "types", Namespace = "http://www.w3.org/2000/xmlns/")]
public string Types { get; set; }
[XmlAttribute(AttributeName = "soap", Namespace = "http://www.w3.org/2000/xmlns/")]
public string Soap { get; set; }
[XmlText]
public string Text { get; set; }
}
问题是 SessionId 元素没有被反序列化,我假设是由于命名空间不匹配。我尝试使用空字符串作为命名空间,但这也不起作用,因为它在反序列化过程中无法被识别。
非常感谢任何对此问题的见解。谢谢!
首先,SessionId
的命名空间有误。它从父级继承,您需要通过将其设置为空字符串来明确指定它没有。
其次,xsi:type
有特殊含义,你不应该尝试反序列化它。它用于指示元素的内容类型 - 在本例中为 string
- 并将由序列化程序使用。这意味着这是许多可接受的类型之一。定义它的最简单方法是使用 object
.
将它们放在一起,这应该有效:
[XmlElement(ElementName = "SessionId", Namespace = "")]
public object SessionId { get; set; }
SessionId
应该包含一个 string
对象,其值为 string
.
我还会注意到其他各种小事:
- 您不应将所有命名空间绑定(例如
Xsd
)指定为模型的一部分。这比此模型级别低,将由序列化程序处理。
- 您只需要
XmlRoot
在根
- 您不需要
XmlText
没有任何文本的属性
- 您需要对上面进行类似的更改以反序列化
Result
ElementName
和 AttributeName
将默认为 属性 的名称,因此如果您想要 ,则不必指定它们
考虑到这一点,这个模型应该可行:
public class SessionInfo
{
[XmlElement(Namespace = "")]
public object SessionId { get; set; }
}
public class Header
{
[XmlElement(Namespace = "http://www.s1.com/info/")]
public SessionInfo SessionInfo { get; set; }
}
public class LoginResponse
{
[XmlElement(Namespace = "")]
public object Result { get; set; }
}
public class Body
{
[XmlElement(Namespace = "http://www.s1.com/info/")]
public LoginResponse LoginResponse { get; set; }
[XmlAttribute("encodingStyle", Namespace = "http://schemas.xmlsoap.org/soap/envelope/", Form = XmlSchemaForm.Qualified)]
public string EncodingStyle { get; set; }
}
[XmlRoot(Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
public class Envelope
{
[XmlElement]
public Header Header { get; set; }
[XmlElement]
public Body Body { get; set; }
}
您可以看到一个工作演示 here。我对源 XML 做了一个更改 - 我将 Result
值从 boolean
更改为 true
,否则你会得到一个异常,因为 boolean
不是该类型的有效值。
