如何在将数据绑定到数据库之后向datagridview添加新列

Question

我的winForm（C＃）应用程序中有一个dataGridView来显示玩家列表。

我已经成功地将它与数据库绑定并显示所有列，即PlayerName，Age，运行等正确。

现在我想添加一列，即'CurrentScore'dataGridView在run time而不添加到数据库。

plz告诉如何执行这个tast。是否有可能以编程方式添加新列？

private void playerList(int teamID) 
    { 


      if (con.State == ConnectionState.Closed) 
      { 
       con.Open(); 
      } 
      string query = "SELECT PlayerName AS [Player Name] ,Age , Runs FROM Players WHERE Team_id= " + teamID; 

      SqlCommand cmd = new SqlCommand(query, con); 
      adapter = new SqlDataAdapter(cmd); 
      adapter.Fill(ds, "Players"); 
      dGridPlayers.DataSource = ds.Tables["Players"]; 

     } 

这段代码可以正常使用，但不能增加新的临时列“CurrentScore`

您可以编辑您的查询，添加一个虚拟列：

string query = "SELECT player_name AS [Player Name] , 
skill As [Skill], '' AS [CurrentScore] 
FROM Players WHERE Team_id= " + teamID;
