我希望将数据表从数据库加载到数据网格视图,但是我得到的错误是"操作&方法未实施"。我在这里查看视频:http://www.youtube.com/watch?v=Sm5mxkytfWk;这是我第一次这样做,希望能够解决它。

以下是我的代码:

private void button1_Click(object sender, EventArgs e)
    {
        string constring = @"Data Source=(LocalDB)\v11.0;AttachDbFilename=C:\Users\oo\Documents\Data.mdf;Integrated Security=True;Connect Timeout=30";
        MySqlConnection conDataBase = new MySqlConnection(constring);
        MySqlCommand cmdDataBase = new MySqlCommand("SELECT* from Data.itemInfo;", conDataBase);

        try
        {
            MySqlDataAdapter sda = new MySqlDataAdapter();
            sda.SelectCommand = cmdDataBase;
            DataTable dbdataset = new DataTable();
            sda.Fill(dbdataset);
            BindingSource bSource = new BindingSource();

            bSource.DataSource = dbdataset;
            dataGridView1.DataSource = bSource;
            sda.Update(dbdataset);
        }

        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }

答案 0 :(得分:0)

MySqlCommand cmdDataBase = new MySqlCommand("SELECT* from Data.itemInfo;", conDataBase); 

你的SQL查询包含额外的分号

SELECT* from Data.itemInfo;

SELECT* from Data.itemInfo
