I'm trying to get my httphandler to print out an XML file with the format:
<ScheduledShows>
<ScheduledShowElement>...</ScheduledShowElement>
<ScheduledShowElement>...</ScheduledShowElement>
<ScheduledShowElement>...</ScheduledShowElement>
</ScheduledShows>
But for some reason, the attribute XmlRoot("ScheduledShowElement") in ScheduledShow.cs is not working the way i want it to work. Instead, the output i get is:
<ScheduledShows>
<ScheduledShow>...<ScheduledShow>
<ScheduledShow>...<ScheduledShow>
<ScheduledShow>...<ScheduledShow
</ScheduledShows>
Basically, the name of the node is not being overriden to . How do i get my xml serializer to label nodes as ?
Below is my code and xml output. Thanks!

I found an answer to my question here:
http://social.msdn.microsoft.com/Forums/en-US/asmxandxml/thread/4b228734-a209-445a-991c-0420b381ac93
I just used [XmlType("")] and that worked.
using System;
using System.Xml.Serialization;
namespace CommunityServer.Scheduler
{
[XmlType("ScheduledShowElement")]
public class ScheduledShow
{
...
}
}
[XmlRoot(...)] only affects the outermost element (<ScheduledShows>...</ScheduledShows>). I suspect you want [XmlElement(...)]. Of course, another way is to write an object wrapper:
[XmlRoot("SheduledShows")]
public class Shows {
[XmlElement("SheduledShowElement")]
public List<Show> Shows {get;set;}
}
And serialize this wrapper object instead of just a list.
