in_ProductData IsNot Nothing AndAlso in_ProductData.Rows.Count > 0
Can some one explain this expression
First part of the expression checks if datatable is not nothing
or null
AndAlso
is a short circuit operator performs short-circuiting logical conjunction on two expressions. This ensures the next part of the expression will execute only if the first part returns true
. If first part returns false
, second part will not execute.
Second part checks if there are more than 0 rows in the datatable.
Refer this for more about AndAlso
logical operator.
Hello @Farah_Kullab
in_ProductData IsNot Nothing
checks if the datatable in_ProductData exists (is not nothing).
AndAlso means that this must be true before the second part of the condition is checked.
in_ProductData.Rows.Count > 0
means that the datatable must contain rows (more than 0).
