哪位知道用流的方法把DataGridView数据导出到Excel时，如何写入指定的sheet中呢
      public static void DataGridViewToExcel(DataGridView dgv)
      {

         SaveFileDialog dlg = new SaveFileDialog();
         dlg.Filter = "Execl files (*.xls)|*.xls";
         dlg.CheckFileExists = false;
         dlg.CheckPathExists = false;
         dlg.FilterIndex = 0;
         dlg.RestoreDirectory = true;
         dlg.CreatePrompt = true;
         dlg.Title = "保存为Excel文件";
         if (dlg.ShowDialog() == DialogResult.OK)
         {
            Stream myStream;
            myStream = dlg.OpenFile();
            StreamWriter sw = new StreamWriter(myStream, System.Text.Encoding.GetEncoding(-0));
            string columnTitle = "";
            try
            {
                  //写入列标题
                  for (int i = 0; i  0)
                     {
                        columnTitle += "\t";
                     }
                     columnTitle += dgv.Columns[i].HeaderText;
                  }
                  sw.WriteLine(columnTitle);
                  //写入列内容
                  for (int j = 0; j  0)
                        {
                              columnValue += "\t";
                        }
                        if (dgv.Rows[j].Cells[k].Value == null)
                              columnValue += "";
                        else
                              columnValue += dgv.Rows[j].Cells[k].Value.ToString().Trim();
                     }
                     sw.WriteLine(columnValue);
                  }
                  sw.Close();
                  myStream.Close();
            }
            catch (Exception e)
            {
                  MessageBox.Show(e.ToString());
            }
            finally
            {
                  sw.Close();
                  myStream.Close();
            }
         }
      }
