Convert String to Double - VB
Is there an efficient method in VB to check if a string can be converted to a double?
I'm currently doing this by trying to convert the string to a double and then seeing if it throws an exception. But this seems to be slowing down my application.
Try ' if number then format it. current = CDbl(x) current = Math.Round(current, d) Return current Catch ex As System.InvalidCastException ' item is not a number, do not format... leave as a string Return x End Try
Try looking at Double.TryParse() if you are using .NET 1.1/2.0/3.0/3.5/4.0/4.5
