Answer 1

給這個一杆，我已經測試它和它的作品：

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;
