I work with VSTO and Excel for some time, at a very intense level, so I hope I can share things I've learned over the course of time with you.

Based on the information you've provided, I'd recommend casting to an object array and working with that information instead. Basically you'd access the values as:

object[,] arrayValues = (object[,])ExcelRange.Value2;

arrayValues is a 2D array ([row,column]). Excel populates the array blazingly fast, and of course operations on the array will be very performant (don't worry about the performance of the boxing, it's NOT an issue, believe me).
