Fastest way to get an Excel Range of Rows

Question

In a VSTO C# project I want to get a range of rows from a set of row indexes.

The row indexes can be for example like \"7,8,9,12,14\".

Then I want the range

Answer 1

Try this:

Sheet.Range("7:9,12:12,14:14")

EDIT: Sorry if using VSTO in C# it should have been:

sheet.get_Range("7:9,12:12,14:14", Type.Missing)
