mysql - Visual Studio 配置数据源 MySQL

Question

好吧，我已经在我的网站上访问了 mysql 数据库。我能够完美连接并从数据库中插入和选择内容。

server = "localhost";
        database = "datamain";
        uid = "root";
        password = "fakepassword";
        string connectionString;
        connectionString = "SERVER=" + server + ";" + "DATABASE=" +
     database + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";";

        connection = new MySqlConnection(connectionString);

现在我想放入一个 ListView 。然后我去选择新的数据源。然后我输入所有数据并测试连接是否有效，然后单击“确定”。现在我已经完成了，所以我单击“完成”。然后它说:

The data provider "MySQL.data.MySQLClient could not be found in the system configuration. Unable to find the requested .NET framework Data provider. It may not be installed

是的，我在 bin 中有引用，因为它让我手动连接到数据库

更新:我什至可以手动获取数据源

 try
    {
        String sCon = "SERVER=localhost;DATABASE=datamain;UID=root;PASSWORD=fakepassword";
        MySqlConnection con = new MySqlConnection(sCon);
        String s = "Select * from tb_login";
        MySqlDataAdapter dat = new MySqlDataAdapter(s, con);
        DataSet ds = new DataSet();
        dat.Fill(ds, "tb_login");
        GridView1.DataSource = ds.Tables[0];
        GridView1.DataBind();
    }

    catch (Exception ex)
    {
        Label1.Text = ex.ToString();
    }

我的 web.config 看起来像这样:

    <?xml version="1.0" encoding="utf-8"?>

我知道如何解决它。我所做的是我去mysql重新下载了连接器，然后重新启动了Visual Studio。然后，当我再次尝试创建数据源时，它成功了。
