  Excel.Range   myrange=mysheet.get_Range(mysheet.Cells[1,1],mysheet.Cells[5,1]);  
  myrange.NumberFormatLocal="@";//文本格式  
   
  //設置第10行爲紅色  
  mysheet.get_Range((Excel.Range)mysheet.Cells[10,1],(Excel.Range)mysheet.Cells[10,200]).Select();  
  mysheet.get_Range((Excel.Range)mysheet.Cells[10,1],(Excel.Range)mysheet.Cells[10,200]).Interior.ColorIndex=3;
