The DataRow/Table Connection
Published 10.25.2007 by ~mattg
Having used a custom data layer for the past two years, I haven’t had to work too much with ADO.NET. Where I’m at now it’s used a bit more frequently, so I’ve gotten the chance to explore it’s idiosyncrasies a bit more. One interesting thing I noted was the connection a DataRow maintains with it’s DataTable when the DataRow is created via the table’s NewRow() function.
DataColumn c = new DataColumn();
c.ColumnName = “Name”;
dt.Columns.Add(c);
DataRow row = dt.NewRow();
row[“Name”] = “My Name”;
DataColumn desc = new DataColumn();
desc.ColumnName = “Description”;
dt.Columns.Add(desc);
row[“Desc”] = “My Description”;
My first thought is that the above wouldn’t work because row would have no idea that I added a column to it’s parent datatable. However, when you create the DataRow using .NewRow(), the link is maintained. So the above works just fine.
