话不多说，上代码！

class clsoledb
  {
    OleDbConnection connection;
    public void OpenConnection(string xlsFils)
    {
      if (!File.Exists(xlsFils))
      {
 MessageBox.Show("文件" + xlsFils + "不存在", "提示");
 return;
      }
      string conn = "Provider = Microsoft.Jet.OLEDB.4.0;Data Source =" + xlsFils + ";Extended Properties='Excel 8.0;HDR=NO;IMEX=1;'";
      connection = new OleDbConnection(conn);
      try
      {
 connection.Open();
      }
      catch (OleDbException ex)
      {
 if (ex.ErrorCode == -2147467259)
 {
   connection.ConnectionString = "Provider = Microsoft.Ace.OLEDB.12.0;Data Source =" + xlsFils + ";Extended Properties='Excel 12.0;HDR=NO;IMEX=1;'";
   connection.Open();
 }
      }
    }

    public DataTable Select()
    {
      DataTable dt = new DataTable();
      string Sql = "select * from [$A1:R65536]";
      OleDbDataAdapter mycommand = new OleDbDataAdapter(Sql, connection);
      mycommand.Fill(dt);

      if (dt.Rows.Count > 0)
      {
 DataRow dr = dt.Rows[0];
 for (int col = 0; col < dt.Columns.Count; col++)
 {
   dt.Columns[col].ColumnName = dr[col].ToString();
 }
 dt.Rows[0].Delete();
 dt.AcceptChanges();
      }
      return dt;
    }

  }
