WinForms DragDrop path length limitation

问题

I'm using WinForms and have a DragDrop operation that handles a file being dragged onto the window. This works fine but if the path to the file is very long it just fails. string[] fileList = (string[]) e.Data.GetData(DataFormats.FileDrop, false); results in fileList being null.

Does anyone know what the limitation is or any way to work around it?

Thanks!

Update: The data in GetFormats is as follows:

Short Filename:

Shell IDList Array UsingDefaultDragImage DragImageBits DragContext DragSourceHelperFlags InShellDragLoop FileDrop FileNameW FileName IsShowingLayered DragWindow IsComputingImage DropDescription DisableDragText ComputedDragImage IsShowingText

Long Filename:

Shell IDList Array UntrustedDragDrop UsingDefaultDragImage DragImageBits DragContext DragSourceHelperFlags InShellDragLoop FileDrop FileNameW FileName
