我正在尝试从xml字符串反序列化为对象。但是我的对象总是空的。
我有一个抽象类(Response),一个继承自“Response”(DirectorSearchResponse)的类,以及一个类“DirectorSearchResponse”(HeaderResponse)中的对象。反序列化后,此对象始终为null。
Response.cs
public abstract class Response
{
public HeaderResponse Header { get; set; }
public Response()
{
}
}
DirectorSearchResponse.cs
[XmlRoot("xmlresponse")]
public class DirectorSearchResponse : Response
{
public DirectorSearchResponse() : base()
{
/* DO NOTHING */
}
}
HeaderResponse.cs
[XmlRoot("header")]
public class HeaderResponse
{
[XmlElement("toto")]
public String toto { get; set; }
public HeaderResponse()
{
}
}
我正在运行的代码:
/* DESERIALIZE */
String toto = "<xmlresponse><header><toto>tutu</toto><reportinformation><time>08/04/2016 13:33:37</time><reporttype> Error</reporttype><country>FR</country><version>1.0</version><provider>www.creditsafe.fr</provider><chargereference></chargereference></reportinformation></header><body><errors><errordetail><code>110</code><desc></desc></errordetail></errors></body></xmlresponse>";
XmlSerializer xsOut = new XmlSerializer(typeof(DirectorSearchResponse));
using (TextReader srr = new StringReader(toto))
{
DirectorSearchResponse titi = (DirectorSearchResponse)xsOut.Deserialize(srr);
}
当我执行我的代码时,对象“titi”是instanciate,但“Header”始终为null。
如何从xml中检索“toto”值?
答案 0 :(得分:1)
XML区分大小写,因此您需要使用[XmlElement("header")]
来通知序列化程序Header
属性的正确元素名称:
public abstract class Response
{
[XmlElement("header")]
public HeaderResponse Header { get; set; }
public Response()
{
}
}
您应用于HeaderResponse
的{{3}}仅在它是XML文档的根元素时控制其元素名称。

您需要将链接添加到抽象类中,如下所示:
[XmlRoot(ElementName = "Response")]
public abstract class Response
{
public HeaderResponse Header { get; set; }
public Response()
{
}
}
[XmlRoot(ElementName = "Response")]
public class DirectorSearchResponse : Response
{
public DirectorSearchResponse() : base()
{
/* DO NOTHING */
}
}
