Hi guys,

I'm trying to clear an XML DataSet that was populated as follow but it's not working:

DataSet ds = new DataSet();
ds.ReadXml("path to xml", XmlReadMode.InferSchema);

ds.Clear();

Here's what MSDN is saying:

"If the DataSet is bound to an XmlDataDocument, calling DataSet.Clear or DataTable.Clear raises the NotSupportedException. To avoid this situation, traverse each table, removing each row one at a time."

http://msdn2.microsoft.com/en-us/library/system.data.dataset.clear.aspx

Does this apply to my case? If so, how can I do it?

Thanks.

Hi EEssam,

As suggested,  traverse each table, removing each row one at a time.....

     {
         foreach (DataTable dt in ds.Tables) {
             foreach (DataRow dr in dt.Rows) {
                 dr.Delete();
             }
         }
     }

Regards,

Wayne

Hi,

Your code is giving an exception when executed.

System.InvalidOperationException: Collection was modified; enumeration operation might not execute.

ds.Clear(); works with XML in my case. I just was missing something in my code... However, I'll accept your solution because it does the job as well.
