HI

I am join two tables without any database,what iam doing is create two datatable from reading excel file and join ad "outer join",I got the coding from internet,and that artical shows how to join two table with "euqi join",So I want to know how to join two tables as outer join.

DataRelation drel = new DataRelation("EquiJoin", dt1.Columns["Destination"], dt2.Columns["Destination"], true);
ds.Relations.Add(drel);

Thanks
