XmlRoot() for Xml Serilization does not work

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.

Hasani Blackwell

You need to use the overloaded constructor that takes in a XmlAttributeOverrides and make sure you override the name of the ScheduledShow class.
