It seems a DataRow can only be created from
DataTable.NewRow()/NewRowArray()/NewRowFromBuilder() method. If I want to
derive a class from DataRow, how can I create it?

In MSDN, the NewRowFromBuilder() seems could do this, but the method is
marked as internal use.
 
Hi Lei,

I doubt that you'll be able to create a derived row.
You could use reflection but that involves hacking the code.
What are you trying to achieve?
 
Thank you for your reply. I have solved this problem. Please refer to
DataTable.GetRowType and DataTable.OnTableNewRow methods you will know how
to do that.
