Reading from Excel (Range into multidimensional Array) C#

You can read the value of Range as array:

using (MSExcel.Application app = MSExcel.Application.CreateApplication()) 
{
    MSExcel.Workbook book1 = app.Workbooks.Open( this.txtOpen_FilePath.Text);
    MSExcel.Worksheet sheet = (MSExcel.Worksheet)book1.Worksheets[1];
    MSExcel.Range range = sheet.GetRange("A1", "F13");

    object value = range.Value; //the value is boxed two-dimensional array
}

This code snippet is from .NET wrapper for MS Office. But same princip is in VSTO or VBA in MS Excel.
