Put SqlDataReader data into a DataTable while i pr

问题:

I want to query a database and with the results, i want to process them. While im processing them, some of them will need to be inserted into another database. Since i cannot run another query with an open SqlDataReader (that i know of). I was thinking about putting the data from the SqlDataReader into a DataTable while i process it. Is there a built in way to do this or is there another solution that can accomplish the same idea?

回答1:

SqlDataReader reader = com.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(reader);

With the rest of the standard set-up and tear-down of SqlCommand objects, of course.

回答2:

The easiest way would be to use a DataAdapter to fill a datatable. Then process the data and update the database. Filling a dataset does not tie up the connection once the fill is complete.
