code不显示 datagridview的事情 为什么呢？

code does not display anything in datagridview why?

class classman
        {
            public int id;
            public string name;
        }

    private void Form2_Load(object sender, EventArgs e)
    {
        testtelContext db = new testtelContext();
        List<classman> qry = (from p in db.firstlasts
                             join i in db.firstnames
                                 on p.Idfname equals i.Idfname
                              select new classman
                             {
                                 id = p.idfl,
                                 name = i.fname

                             }).ToList();
      BindingSource bs=new BindingSource();
        bs.DataSource = qry;
        dataGridView1.DataSource = bs;

    }

有一个在BindingSource的值，但它并没有显示dataGridView5显示图片 https://m.xsw88.com/allimgs/daicuo/20230903/1633.png.jpg

推荐答案

大概需要这样的：

dataGridView1.DataBind();

右键后，您设置数据源。

Right after you set the data source.
