Xml序列化顺序问题

通常，所有这些工作对于将我的对象序列化为一个Xml字符串并返回到一个对象中都很有用。但是，我在不同的最终用户之间出现了我似乎无法跟踪的不一致情况。Xml序列化顺序问题

基本上，当我序列化一个对象，它看起来像这样一次转换为XML：

<?xml version="1.0" encoding="utf-8"?>

然而，当其他随机用户运行了一个程序，他们序列化对象，他们最终与此相反：

你会发现，它是在VoltageDip和负载在不同的顺序不同。所以它似乎不符合模式中设置的序列。在用户反序列化Xml字符串后会发生什么情况，Name，Load和VoltageDip属性是否设置为其默认值（对于引用类型和字符串为null，对于int为0），而不是在序列化过程中保存的值。

使用该应用程序的每个人都使用相同的源代码。

谁能告诉我发生了什么？为什么不同用户/机器之间的序列化元素顺序会改变？为什么反序列化过程在发生时无法处理？

大柏林墙。 'ToChar（60）'后我停止阅读。不知何故，你的评论被剥夺了。 – 2011-03-17 17:49:35

尝试在你的属性上的XmlElement属性使用为了对于前 - 代码的

[XmlElement(Order = 1)] 
public string Prop1{get;set;} 

[XmlElement(Order = 2)] 
public string Prop1{get;set;}
