Answer 1

给这一个镜头，我已经testing它，它的工作原理：

 Excel.Application application = new Excel.Application(); Excel.Workbook workbook = application.Workbooks.Open(@"C:\Test\Whatever.xlsx"); Excel.Worksheet worksheet = workbook.ActiveSheet; Excel.Range usedRange = worksheet.UsedRange; Excel.Range rows = usedRange.Rows; int count = 0; foreach (Excel.Range row in rows) { if (count > 0) { Excel.Range firstCell = row.Cells[1]; string firstCellValue = firstCell.Value as String; if (!string.IsNullOrEmpty(firstCellValue)) { row.Interior.Color = System.Drawing.Color.Red; } } count++; } workbook.Save(); workbook.Close(); application.Quit(); Marshal.ReleaseComObject(application);

 Excel.Application xlAppToExport = new Excel.Application(); xlAppToExport.Workbooks.Add(""); Excel.Worksheet xlWorkSheetToExport = default(Excel.Worksheet); xlWorkSheetToExport = (Excel.Worksheet)xlAppToExport.Sheets["Sheet1"]; xlWorkSheetToExport.Range["A5:F5"].EntireRow.Interior.Color = System.Drawing.Color.Gray;
