Question

我尝试通过泛型（List<T>）反序列化嵌套的XML。反序列化未嵌套的XML是可行的，但是嵌套的版本则不能。

XML：

<?xml version="1.0" encoding="utf-8"?>
<Users xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
                     xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<User>
    <UserId>1</UserId>
    <LoginData>
        <LoginName>Albert</LoginName>
        <Password>albert</Password>
    </LoginData>
    <UserData>
        <FirstName>Albert</FirstName>
        <Surname>Einstein</Surname>
        <BirthDate>2879-03-14T00:00:00</BirthDate>
        <BirthPlace>German</BirthPlace>
        <AddressCity>Württemberg</AddressCity>
    </UserData>
</User>
</Users>

UserData.cs：

[Serializable]
public class MainData
{
    public int UserId { get; set; }
    public LoginData TestLoginData { get; set; }

    public UserData TestUserData { get; set; }
}

public class LoginData
{

    public string LoginName { get; set; }
    public string Password { get; set; }
}

public class UserData
{
    public string FirstName { get; set; }
    public string Surname { get; set; }
    public DateTime BirthDate { get; set; }
    public string BirthPlace { get; set; }
    public string AddressCity { get; set; }
}

反序列化：

public class XmlDataManager<T> : IDataManager<T> 
    where T : class
{
    public List<T> Load(string pathAndName)
    {
        List<T> result = null;

        StringReader stream = null;
        XmlTextReader reader = null;

        var xDocument = XDocument.Load(pathAndName);
        string xml = xDocument.ToString();

        XmlRootAttribute xRoot = new XmlRootAttribute();
        xRoot.ElementName = "Users";
        xRoot.IsNullable = true;

        try
        {
            stream = new StringReader(xml);
            reader = new XmlTextReader(stream);

            result = new XmlSerializer(typeof(List<T>), 
                     xRoot).Deserialize(reader) as List<T>;
         }
        catch (Exception ex)
        {
            Console.WriteLine(ex.GetBaseException());
        }
        return result;
    }

    // more code.....
  }
}

User.cs的一部分：

[Serializable]
public class User : NotificationObject
{
    MainData data;

    public User()
    {
        data = new MainData();
    }

    //more code.....

    public override string ToString()
    {
        return UserId + LoginName + Password + FirstName + Surname + 
               BirthDate + BirthPlace + AddressCity;
    }

    //more code.....

    public int UserId
    {
        get { return data.UserId; }

        set
        {
            NotifyPropertyChanging("UserId");
            data.UserId = value;
            NotifyPropertyChanged("UserId");
        }
    }

    public string LoginName
    {
        get { return data.TestLoginData.LoginName; }

        set
        {
            NotifyPropertyChanging("LoginName");
            data.TestLoginData.LoginName = value;
            NotifyPropertyChanged("LoginName");
        }
    }

    .....

我不知道为什么要导入XML数据：

var xDocument = XDocument.Load(pathAndName);
string xml = xDocument.ToString();

但是反序列化给了我空值。怎么了？

问题是您在类中的命名与xml中的命名不匹配。以下内容可以帮助您：

setCustomValidity('Please fill this field.')

尝试使用list <t>
