UPDATE: You can run the code at the end of this to recreate and see the error I am having and hopefully solve it!
UPDATE2: It's not the removal of the xmlns="" that's the issue... as you can remove it from the initial xml string. The problem is with the [XmlType(TypeName = "Systems")] somehow causing it to be added...
UPDATE3: Turns out the problem is in here, I need to set the TypeName based on what is in the existing, XmlTypeAttribute if it already exists on the class....
xmlAttributes.XmlType = new XmlTypeAttribute
{
Namespace = ""
};
I get the following XML as a string from a webservice
<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>
I then execute this, to convert it to an object
result = XElement.Parse(xmlResult.OuterXml).Deserialize<AwayRequestSystems>();
Strangely though, in the Deserialize
method, while the RemoveAllNamespaces works and returns the xml without the namespace
I get the error <Systems xmlns=''> was not expected. in the catch when return (T) serializer.Deserialize(reader); executes!
Why is it doing this? The xmlns is GONE!!!
