我有如下代码：
[DataContract(Namespace = "")]
public class User
{
[DataMember]
public string UserName { get; set; }
[DataMember]
public string FullName { get; set; }
}
//Deserialization test
public void Test()
{
//CASE 1.
//string xml = "<User><UserName>john</UserName>" +
// "<FullName>John Lennon</FullName></User>";
//CASE 2.
string xml = "<User><FullName>John Lennon</FullName>" +
"<UserName>john</UserName></User>";
byte[] byteArray = Encoding.UTF8.GetBytes(xml);
User user = null;
using (MemoryStream stream = new MemoryStream(byteArray))
{
DataContractSerializer serializer =
new DataContractSerializer(typeof(User),"User","");
user = (User)serializer.ReadObject(stream);
}
}
在情况1中,FullName属性不反序列化,但是如果2它被反序列化正确.为什么？
因为顺序很重要使用字母顺序,除非您在DataMember属性中指定顺序.
原文链接：https://www.f2er.com/xml/292239.html这在this MSDN article中解释.
通常,在DataMember属性上始终明确指定Order是一个很好的做法：
[DataMember(Isrequired=true,Order=0)] public string FullName { get; set; } [DataMember(Isrequired=true,Order=1)] public string UserName { get; set; }
