Cannot change the DataSet name once the DataSet is mapped to a loaded XML document.

Paris Hilton

I get the following error:

"Cannot change the DataSet name once the DataSet is mapped to a loaded XML document. "

This is my code

DataSet ds = new DataSet();
XmlDataDocument xdd = new XmlDataDocument(ds);
String fileName = Resources.FILE_NAME;
ds.ReadXmlSchema(fileName);

Does anyone have any idea what I could have done wrong?

Manish, thanks for the article. Unfortunately it didn't help me fix my problem. I still put it under my favourites because I am sure I will need it some day.

I noticed that my code works when I put it in my form code. However, I don't want to read an xml file in a form because reading an XML file has nothing to do with UI logic. Moreover, I need to use my dataset in more than one form.

So I created a class that has my DataSet as a static member. And than I get the above error when I run my code.

Can anyone explain why I get this error: "Cannot change the DataSet name once the DataSet is mapped to a loaded XML document" when I have a static DataSet and I don't get the error when my DataSet is not static?

Thanks so much.
