WCF DataContract数据成员的订单？ [英] WCF DataContract DataMember order?

问题描述

是从按字母顺序排列创建了DataContract创建的XML。我有一个DataContract类定义为：

Is the xml that is created from your DataContract created in alphabetical order. I have a DataContract class defined as:

[DataContract(Name = "User", Namespace = "")]
public class User
{
    [DataMember]
    public string FirstName { get; set; }
    [DataMember]
    public string LastName { get; set; }
    [DataMember]
    public string Email { get; set; }
    [DataMember]
    public string Password { get; set; }

}

当我做了下面的帖子：

<User>
   <FirstName>abc</FirstName>
   <LastName>123</LastName>
   <Email>[e-mail]</Email>
   <Password>pass</Password>
</User>

当我做了我的帖子后，GET和返回JSON作为结果，电子邮件是空的，但如果我发布我的XML为：

When I did a GET after my post and returned the result as JSON, email was null, but if I POST my xml as:

 <User>
   <Email>[e-mail]</Email>
   <FirstName>abc</FirstName>
   <LastName>123</LastName>
   <Password>pass</Password>
 </User>

电子邮件不再是空当我做了GET并返回为JSON。为什么要这样做呢？

Email is no longer null when I do a GET and return it as JSON. Why is it doing this?

推荐答案

与装饰它在订单参数在DataMemberAttribute类：

decorate it with the Order Parameter in the DataMemberAttribute class:

[DataMember(Order = index)]

在串行反射所说的字母顺序。
除非当装饰是这样的：

The reflector in the serializer puts it alphabetically. Unless when decorated like this:

[DataMember(Order = 0)]
public string FirstName { get; set; }
[DataMember(Order = 1)]
public string LastName { get; set; }
[DataMember(Order = 2)]
public string Email { get; set; }
[DataMember(Order = 3)]
public string Password { get; set; }
