通常,这一切都非常适合将我的对象序列化为Xml字符串并再次返回到对象中.但是,我有不同的最终用户之间的这种不一致,我似乎无法追查.

基本上,当我序列化一个对象时,它看起来像转换为Xml后：

</Step>

你会发现它的不同之处在于VoltageDip和Loads的顺序不同.所以它似乎与模式中设置的序列不匹配.在用户反序列化Xml字符串之后会发生什么,Name,Loads和VoltageDip属性被设置为它们的默认值(引用类型和字符串为null,int为0)而不是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Serializtion元素顺序会发生变化？为什么反序列化过程在发生时不能处理？

解决方法

尝试在属性的XmlElement属性上使用顺序
对于前 –

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

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