急,C#对多个sheet的操作
我先在在一个excel里面有3个sheet,我已经把前2个sheet的值取出并进行比较,现在想在每次比较玩之后,直接存进第3个sheet里面,下面是我的代码:
for (int i = 0; i < dataTable.Rows.Count; i++)
  {

  if (!(dataTable.Rows[i][5]).ToString().Equals("") && !(dataTable.Rows[i][6]).ToString().Equals(""))
  {
  lat1 = Convert.ToDouble(dataTable.Rows[i][5]);
  lng1 = Convert.ToDouble(dataTable.Rows[i][6]);
  }
  else
  {
   
  continue;
  }
   
  for (int j = 0; j < dataTable1.Rows.Count; j++)
  {
   
  if (!(dataTable1.Rows[j][7]).ToString().Equals("") && !(dataTable1.Rows[j][8]).ToString().Equals(""))
  {
  lat2 = Convert.ToDouble(dataTable1.Rows[j][7]);
  lng2 = Convert.ToDouble(dataTable1.Rows[j][8]);
  }
  else
  {
   
  continue;
  }
   
  l= GetDistance(lat1, lng1, lat2, lng2);
  //需要输出l
  if (l < 100 && l > -100)
  {
   
   
  }
  }
请问,在if里面应该怎么写,小弟新手,求大神知道!急需!!!
