Which is faster? Dim dv As New DataView(session("myDataTable")) or CType(session("myDataTable"))

[Andreas Klemt]

Hello,
let's say my session("myDataTable") is type of DataTable

Now what is faster?

a) Dim dv As New DataView(session("myDataTable"))
b) Dim dv As New DataView(CType(session("myDataTable"), DataTable))

Which should I use and which is better?


Thanks in advance,
Andreas

They are both equivalent because the conversion happens whether you specify
it or not.
If you have Option Strict turned on (which every good programmer should)
then only your second example will work anyway so the subject becomes moot.
