I have a function that returns a SqlDataReader created by:
result = command.Execute Reader(CommandB ehavior.CloseCo nnection);
I then bind the result to a grid control:
myDataGrid.Data Source = sr;
myDataGrid.Data Bind();
Do I need to explicitly close the DataReader (and thus the connection) after
the DataBind?
Thanks,

your function should use sqlreader.close . That should also take care of the
connection but I see your CommandBehavior is also taking care of the closing
the connection . In the calling client user sr = nothing.

If I do:
sr = null;
Won't this just flag the object for deletion until the garbage collection
actually destroys it? If I need to explicity close the reader, would it not
be better to call the Close method?
Anyhow, so I guess you are saying by this that I could also wait until the
Grid goes out of scope which will also set the sr to null.
Thanks

This is a sample
Try
DR = db.ExecuteReade r(whatever)
While DR.Read
MsgBox(DR.Item( 0))
End While
Catch ex As Exception
MsgBox(ex.Messa ge)
Finally
If (Not DR Is Nothing) Then
DR.Close()
End If
End Try
look at the finally block and convert to c#.

Bill,
sr = null; or sr = nothing does in my opinion absolute nothing here, when
your page is sent back, everything that is not shared will be completely
released by the GC at the right time.
Clossing a connection is always needed of the connection pooling.
(Which you did as Chris already wrote)
I hope this gives an idea

Hi,
My project must connect to a Sql Server quite often to read/write datas.
I am wondering : do i have to open the connection to the Sql Server at the
beginning when the application loads, then
leave the connection open and close it when the application closes ? Or is
it more efficient toopen and close the connection each time i have to use a
datareader, a command etc...
Thanks !

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
