C# interop Excel: is possible to set NumberFormat like Value2?

Question

I am trying to set NumberFormat in Excel with C# for quite big Range. Its big table and make it cell by cell consume too much time.

I tried it similar like setting Value2 for range:

 rng = ws.get_Range("H" + 2, "S" + 2);
 rng.NumberFormat = numberFormat;

Where numberFormat is array of objects with formatting strings (like "0.00", "0.0000", ...) Looks like this will not work because it looks to me, that NumberFormat is just one property for whole Range.

Do you have any idea how to make it fast, not cell by cell approach? Thank you!
