当我尝试将xml字符串反序列化为.net列表对象时出现奇怪的错误 [英] Weird error when i try to Deserialize a xml string to a .net List Object
问题描述
我已经问过这个问题两次，但是没有人给我一个切实可行的答案，所以我会再试一次。我有这个xml：
I have asked this question twice already but not one have given me an answer that actually works so i will try again. I have this xml:
<?xml version="1.0" encoding="UTF-8"?>
<people type="array">
<person>
<first-name>Mark</first-name>
<last-name>Zette</last-name>
<e-mail>mark.zette@hotmail.com</e-mail>
</person>
<person>
<first-name>Sara</first-name>
<last-name>Brobro</last-name>
<e-mail>brobro@hotmail.com</e-mail>
</person>
<person>
<first-name>Rob</first-name>
<last-name>Sel</last-name>
<e-mail>rob.selhotmail.com</e-mail>
</person>
<person>
<first-name>Aden</first-name>
<last-name>Snor</last-name>
<e-mail>aden.Snor@hotmail.com</e-mail>
</person>
</people>
所以我想将此xml转换为该对象的列表：
So I want to turn this xml into a list of this object:

此类是自动生成的。通过在Visual Studio命令提示符下运行 xsd.exe peoples.xml，然后运行 xsd.exe / c peoples.xsd。
This class is autogenerated. Throug running "xsd.exe peoples.xml" and then "xsd.exe /c peoples.xsd" in the visual studio command prompt.
现在，这是我的代码加上错误：（对于那些在补充信息后不懂瑞典语的人，它会说您的XML文档（3,2）出了问题）
Now this is my code plus error: (And for those that don't know Swedish after additional information it says "There is something wrong with your XML-document(3,2)")
< a href = https://i.stack.imgur.com/EySoC.png rel = nofollow noreferrer>
string xmlPath = Path.Combine(HostingEnvironment.MapPath("~/App_Data"), "peoples.xml");
StreamReader sr = new StreamReader(xmlPath);
string xml = sr.ReadToEnd(); //i suspect the problem might appear here maybe. When i convert the xml to string it might
//happend something to the xmlstring that the deserialize
//method cant read. But i dont know just guessing.
XmlSerializer serializer = new XmlSerializer(typeof(List<people>));
using (TextReader reader = new StringReader(xml))
{
List<people> person = (List<people>)serializer.Deserialize(reader);
}
return View();
推荐答案
您的XML文件不表示 List< people> -它包含一个单个 people ;这就是根元素。然后包含子元素。不过，您可以轻松获得它们：
Your XML file doesn't represent a List<people> - it contains a single people; that's what the root element is. That then contains sub-elements. You can get those easily though:
XmlSerializer serializer = new XmlSerializer(typeof(people));
using (TextReader reader = new StringReader(json))
{
people person = (people) serializer.Deserialize(reader);
List<peoplePerson> list = person.person.ToList();
Console.WriteLine(list.Count); // Prints 4
}
（强烈建议您重写自动生成的代码遵循.NET命名约定并使用自动实现的属性。）
(I'd strongly advise you to rewrite the autogenerated code following .NET naming conventions and using automatically implemented properties though.)
