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 "7:9,12,14" rows.

I now do this:

Range rng1 = sheet.get_Range("A7:A9,A12,A14", Type.Missing);
rng1  = rng1.EntireRow;

But it's a bit inefficient due to string handling in range specification.

sheet.Rows["7:9"]

works but I can't give this

sheet.Rows["7:9,12,14"] // Fails

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
