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

This code assign color to range cells based on criteria:

using Microsoft.Office.Interop.Excel;

(...)

var excel = new Application { Visible = true };
Workbook workbook = excel.Workbooks.Add(XlSheetType.xlWorksheet);
Worksheet sheet = workbook.Sheets[1];


var i = 2;
foreach (Data d in this.Datos)
{
    sheet.Cells[i, 1].Value = d.Fecha;
    sheet.Cells[i, 2].Value = d.Ubicacion;
    sheet.Cells[i, 3].Value = d.Lote;
    sheet.Cells[i, 4].Value = d.ArticuloId;
    sheet.Cells[i, 5].Value = d.Articulo;
    sheet.Cells[i, 6].Value = d.ColorId;
    sheet.Cells[i, 7].Value = d.Color;
    sheet.Cells[i, 8].Value = d.StockOriginal;
    sheet.Cells[i, 9].Value = d.Diferencia;
    sheet.Cells[i, 10].Value = d.StockFinal;
    if (d.BackGroundColor == "#FFA061")
        sheet.Range[sheet.Cells[i, 1], sheet.Cells[i, 10]].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.FromArgb(255, 160, 97));
    i++;
}
