我已经阅读了尽可能多的文章,我之前已经按照这种方式进行了序列化,但是我的生活中我无法弄清楚为什么以下内容无法正常工作。
协助表示赞赏。
鉴于此代码:
解除反应的POCO课程:
[XmlRoot]
public class MyResponseClass
{
[XmlElement("response")]
public Response Response { get; set; }
}
[XmlRoot]
public class Response
{
[XmlElement("error")]
public Error Error { get; set; }
[XmlElement("sid")]
public string Sid { get; set; }
}
[XmlRoot]
public class Error
{
[XmlElement("error_msg")]
public string ErrorMessage { get; set; }
}
请求和响应处理代码:
var webClient = _webClientWrapperFactory.Create();
var url = "https://serviceendpoint.com";
var responseString = webClient.DownloadString(url);
MyResponseClass result;
var serializer = new XmlSerializer(typeof(MyResponseClass));
using (var reader = new StringReader(responseString))
{
result = (MyResponseClass) serializer.Deserialize(reader);
}
return result;
返回此回复:
<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><response><error><error_msg>CANNOT_LOGIN</error_msg></error></response>
反序列化尝试会抛出此错误:
类型&#39; System.InvalidOperationException&#39;的例外情况发生在System.Xml.dll中但未在用户代码中处理
其他信息:XML文档中存在错误(1,57)。
编辑: 内部例外:
{"<response xmlns=''> was not expected."}
答案 0 :(得分:1)
我创建了MyResponseClass
的快速实例并将其序列化:
<?xml version="1.0" encoding="utf-16"?>
<MyResponseClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<response>
<error>
<error_msg>error message text</error_msg>
</error>
<sid>(sid string)</sid>
</response>
</MyResponseClass>
这就是MyResponseClass
的XML应该是什么样的。这是我使用的序列化代码:
MyResponseClass result1 = new MyResponseClass
{
Response = new Response
{
Sid = "(sid string)",
Error = new Error
{
ErrorMessage = "error message text"
}
}
};
var serializer = new XmlSerializer(typeof(MyResponseClass));
string serialized = "";
using (StringWriter textWriter = new StringWriter())
{
serializer.Serialize(textWriter, result1);
serialized = textWriter.ToString();
}
但那可能不是你想要的。
如果您想坚持使用问题中的XML,则需要省略MyResponseClass
并指定Response
作为XML根,全部为小写:
[XmlRoot("response")]
public class Response
{
[XmlElement("error")]
public Error Error { get; set; }
[XmlElement("sid")]
public string Sid { get; set; }
}
...
var responseString = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><response><error><error_msg>CANNOT_LOGIN</error_msg></error></response>";
var serializer2 = new XmlSerializer(typeof(Response));
//using (StringWriter textWriter = new StringWriter())
//{
// serializer2.Serialize(textWriter, result1.Response);
// responseString = textWriter.ToString();
//}
Response result;
using (var reader = new StringReader(responseString))
{
result = (Response)serializer2.Deserialize(reader);
}
