更新：您可以在此结束时运行代码以重新创建并查看我遇到的错误并希望能够解决它！命名空间和反序列化问题
UPDATE2：这不是删除xmlns =“”这是问题......因为您可以从最初的xml字符串中删除它。问题是[XmlType（TypeName =“系统”）]以某种方式导致它被添加...
UPDATE3：原来的问题是在这里，我需要设置TypeName根据什么是在现有的XmlTypeAttribute如果已经在类存在....
xmlAttributes.XmlType = new XmlTypeAttribute
{
Namespace = ""
};
我得到以下XML作为字符串从Web服务
<Systems xmlns="">
<System id="1">
<sys_name>ALL</sys_name>
</System>
<System id="2">
<sys_name>asdfasdf</sys_name>
</System>
<System id="3">
<sys_name>fasdfasf</sys_name>
</System>
<System id="4">
<sys_name>asdfasdfasdf</sys_name>
</System>
</Systems>
然后我执行此，将其转换为一个对象
result = XElement.Parse(xmlResult.OuterXml).Deserialize<AwayRequestSystems>();
奇怪的是，虽然，在反序列化方法，而RemoveAllNamespaces作品，并返回XML没有命名空间
我得到的错误<Systems xmlns=''> was not expected.在捕捉时return (T) serializer.Deserialize(reader);执行！
它为什么这样做？ xmlns是GONE !!!
