ColumnEnum was just an example of an enum you would create to access the
columns in your SqlDataReader
enum ColumnEnum
{
Id, Category, etc
}
this way you are accessing the columns by their int index, rather than their
name, which is obviously faster.

Thanks!

record stream so your code should be
if ( dr.Read() )
{
//perform actions on row
}
and...btw, use enums rather than strings to access your columns...it's
quicker
if ( (string)dr[Convert.ToInt32(ColumnEnum.Category)] == "xmlsrc" )

news:bg**********@news4.tilbu1.nb.home.nl... Hello,
How can I check the recordcount?
Here is a little bit of my code:
// Load first row into Datareader
dr.Read();
if (dr["Category"].ToString() == "xmlsrc") {
When I do this I get an error because there is no data... it only have
to check this dr["Category"].ToString() == "xmlsrc") if there is data.
How can I do that?
Thanks!
