is this redundant...

[Guest]

hey all,

Private Property mEmployeeDataset() As DsHRLIBR24
Get
Return DirectCast(Session("oDs"), DsHRLIBR24)
End Get
Set(ByVal Value As DsHRLIBR24)
Session("oDs") = Value
End Set
End Property

Is my DirectCast needed in this case?

thanks,

If you will be able to compile without it then no.

I do not know much about VB.NET in C# you must you cast in cases like that.

Not needed, but certainly acceptable. And not redundant.

The difference between CType and DirectCast is that CType will work as long
as there is a valid conversion defined for the expression and the object
type specified, whereas DirectCast will only work if the run-time types are
the same. For example:

Dim i As Integer = CType("23", Integer) 'Fine
Dim i As Integer = DirectCast("23", Integer) ' Exception
