      OleDbConnection strConnection = new OleDbConnection("Provider = Microsoft.ACE.OLEDB.12.0;Data Source=" + "test.accdb" + ";Persist Security Info=False");
       //建立數據庫引擎連接，注意數據表（後綴爲.db）應放在DEBUG文件下 Provider = Microsoft.ACE.OLEDB.12.0
      OleDbDataAdapter myda = new OleDbDataAdapter("select * from 表1" ,strConnection);
     //建立適配器，通過SQL語句去搜索數據庫
      DataSet myds = new DataSet();
       //建立數據集
      myda.Fill(myds, "表1");
      return myds;
  }

      try
      {
          strConnection.Open();
          OleDbCommand command = new OleDbCommand(strsql, strConnection);
          int rows = command.ExecuteNonQuery();
          strConnection.Close();
          strConnection.Dispose();
