A:
As I recall
TypeOf data Is System.Data.DataView
Edit:
As James Curran pointed out, this works if data is a subtype of System.Data.DataView as well.
If you want to restrict that to System.Data.DataView only, this should work:
data.GetType() Is GetType(System.Data.DataView)

Note, however, if the VB "is" is anyhting like the C# "is", that would be true if data is a DataView or derived from DataView. The original code would only be true if data was specifically a DataView object.

@James Curran: Good point, I've updated it with the other way I know of to check that (ironically, the way I originally had it before editing)

@James: VB’s `Is` is actually identical to `object.ReferenceEquals`. But `Typeof … Is` indeed equals C#’s `is` operator.
