Data Frame Rotation

Question

Using VB.NET, I'm trying to rotate the display view, like the Rotation option in the Data Frame Properties. I can only find VBA codes on it and I'm trying to convert it into .NET, but I'm having trouble.  
            Dim pMap As IMap = My.ArcMap.Document.ActiveView Dim pActiveView As IActiveView = pMap.FocusMap pActiveView.ScreenDisplay.DisplayTransformation.Rotation = 90 pActiveView.Refresh()

I think your code should be:Dim pActiveView As IActiveView  pActiveView = My.ArcMap.Document.ActiveView pActiveView.ScreenDisplay.DisplayTransformation.Rotation = 90 pActiveView.Refresh()
