http://bugzilla.novell.com/show_bug.cgi?id=591397#c5 --- Comment #5 from Tony Fish <[email protected]> 2010-03-27 00:27:58 UTC --- Miguel Just to be completely clear about what I'm doing. The only part of MONO I'm using is the DataExtensions. Everything else is .NET 2 .I'm doing this because .Net 2.0 does not include LINQ which I need, but can not use .Net 3.x. So I use an open source implementation to allow me to do LINQ over objects called LinqBridge. However LinqBridge (LINQ over objects) does not include the extension methods needed for working with datatables dat rows etc. This is why I use MONO DataExtensions to provide this functionality When the code calls the extension method o.CopyToDataTable() DatatableExtensions.cs eventually invokes public static void CopyToDataTable<T> (this IEnumerable<T> source, DataTable table, LoadOption options, FillErrorEventHandler errorHandler) where T : DataRow { var reader = new RowEnumerableDataReader (source, 0); table.Load (reader, options, errorHandler); } Now keep in mind the code line table.Load (reader, options, errorHandler); When the table is a .NET version 2, the first call made by the table on the reader is the sub public void Close () { e = null; } of RowEnumerableDataReader.cs This is why I added this line to the contructor //tf Added cos isClosed is called fist by MS _e = ((IEnumerable)this._source).GetEnumerator(); If e does not get set in the constructot , the .NET table thinks the reader is closed and returns an un populated table. So I've taken a look at your patched constructor now on CVS and added 1 line back. ( please see attachment ). RowEnumerableDataReader.cs will now be more compatible with .NET as well as MONO -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
