[RESOLVED] Which is more efficient?

[tsungik]

Hello to all,

Just want to hear your ideas on which of the following code is more efficient.

Dim TotalUnits as Double
 
' some codes here ...
 
Try
   Units += ds.Tables(0).Rows(i).Item("UNITS")
Catch ex As Exception
   ' Set Units to zero if error occur.
   Units = 0
Finally
   TotalUnits += Units
End Try

or using if statement.

' Check if the column UNITS is NULL
If IsDBNull(ds.Tables(0).Rows(i).Item("UNITS")) Then
   Units = 0
Else
   Units = ds.Tables(0).Rows(i).Item("UNITS")
End If
' Add to TotalUnits variable.
TotalUnits += Units

Thanks.
