Question

I have a resultset which is selected from inner joined tables with
LINQ. How can i can return resultset as DataTable?

DataProviderDataContext db = new DataProviderDataContext();

IEnumerable<DataRow> asd = (IEnumerable<DataRow>)(from dsa in (from usrAddr in db.T_USER_ADDRESSes join usr in db.T_USERs on usrAddr.USER_ID equals usr.USER_ID where usr.USER_ID == UserID select new { usr.REALNAME, usrAddr.USER_ID, usrAddr.USER_ADDRESS_ID, usrAddr.ADDRESS, usrAddr.TITLE, usrAddr.IS_DELIVERY, usrAddr.IS_INVOICE }).AsEnumerable() select dsa);

DataTable dt = asd.CopyToDataTable<DataRow>();

Best Regards.

Unfortunately CopyToDataTable<DataRow>() operates on an IEnumerable<DataRow>. You need to shred the returned data as outlined here: http://msdn.microsoft.com/en-us/library/bb669096.aspx
