var currentWorksheet = ExcelPkg.Workbook.Worksheets.First();
currentWorksheet.Workbook.CalcMode = ExcelCalcMode.Automatic;
int row = numberofrows;
int col = numberofcolumns;

                string startCell = "B3";

                foreach (var item in parts)
                {
                    string statement = "=$C$" + FormsCount + " = " + "\"" + "" + item.RarityName + "\"";
                    AddConditionRange(currentWorksheet, row, col, 2, StartCoumn, statement, item.RarityName);
                }



                ExcelPkg.SaveAs(stream);

private void AddConditionRange(ExcelWorksheet currentWorksheet, int row, int col, int startCol, int startRow, string statement, string color)
{

        string addressRange = "";

        for (int i = startRow; i <= startRow + row - 1; i++)
        {
            for (int j = startCol; j <= startCol + col - 1; j++)
            {
                // ExcelAddress _formatRangeAddress = new ExcelAddress("$A$" + i);
                //ExcelAddress _formatRangeAddress = new ExcelAddress(i, j, 0, 0);
                string val = currentWorksheet.Cells[i, j].Value.ToString();

                if (currentWorksheet.Cells[i, j].Value.ToString().Contains(color))
                {
                    string startColStr = "";
                    startColStr = GetAlpFromNum(j, ref startColStr);

                    //  f.Address.Address = f.Address.Address + "," + "$" + startColStr + "$" + i;
                    addressRange = addressRange + "," + "$" + startColStr + "$" + i;

                }


            }
        }
      string address=  addressRange.TrimStart(',');

        OfficeOpenXml.ConditionalFormatting.Contracts.IExcelConditionalFormattingExpression f = currentWorksheet.ConditionalFormatting.AddExpression(new ExcelAddress(address));

        f.Style.Fill.BackgroundColor.Color = Color.Gray;
        f.Style.Font.Color.Color = System.Drawing.Color.Green;

        f.Formula = statement;

    }
