duplicate attributes error after xsd tool

May 07, 2010 10:09 AM|LINK

Hi,

I've got a class that was generated from an xsd file which was originally generated from an xml file. The only issue is when I compile the project I get "Duplicate [atttibute] attribute" errors on the root class. The class attributes look like so:

/// <summary>
///Represents a strongly typed in-memory cache of data.
///</summary>
[global::System.Serializable()]
[global::System.ComponentModel.DesignerCategoryAttribute("code")]
[global::System.ComponentModel.ToolboxItem(true)]
[global::System.Xml.Serialization.XmlSchemaProviderAttribute("GetTypedDataSetSchema")]
[global::System.Xml.Serialization.XmlRootAttribute("Maps")]
[global::System.ComponentModel.Design.HelpKeywordAttribute("vs.data.DataSet")]
public partial class Maps : global::System.Data.DataSet {

The duplicate errors are on System.Serializable, System.Xml.Serialization.XmlRootAttribute("Maps") and System.ComponentModel.DesignerCategoryAttribute("code"). If I remove them I then can't access the xml file via the class.

Any help would be greatly appreciated.

Thanks in advance.

Michael

Re: duplicate attributes error after xsd tool

Hi,

Sorry. Just realised I posted the class. The xsd is:

<?xml version="1.0" encoding="utf-8"?>
