Replace CType

Question

Hello all

In my code below I wanna replace CType by Try/Direct Cast / Convert.ToX / etc

Which one is the best fit to use? :)

Private Sub DataListViewEx_DragDrop(sender As Object, e As System.Windows.Forms.DragEventArgs) Handles DataListViewEx.DragDrop
    Dim MyData() As String = CType(e.Data.GetData(DataFormats.FileDrop), String())

Answer 1

Each approach has its advantages and considerations:

• Use TryCast when you want to handle a potential failure gracefully and continue with the program execution even if the cast fails.
• Use DirectCast when you are confident that the cast will always succeed and want to raise an exception if it doesn't.
• Use Convert.ToX when you are converting the object to a different data type, and you are sure that the conversion will work without raising an exception.
