我怎样才能使这两个函数仅是void（）？

Question

我有一个代码，可以将数据加载到网格视图中，并允许用户编辑和更新表。

为此，我“强迫”自己绕过Adapter实例。

如何避免这种情况，所以这2个功能只会无效？

public static MySqlDataAdapter LoadMySQLData(DataGridView dgv, string RequestTableQuery)
    {
        MySqlConnection privateConnection = new MySqlConnection(ConnectionString);
        MySqlDataAdapter adapter = new MySqlDataAdapter(RequestTableQuery, privateConnection);
        DataTable dt = new DataTable();
        adapter.Fill(dt);
        BindingSource bs = new BindingSource { DataSource = dt };
        dgv.DataSource = bs;
        return adapter;
    }

    public static void SaveMySQLData(DataGridView dgv, MySqlDataAdapter adapter)
    {
        BindingSource bs = dgv.DataSource as BindingSource;
        bs.EndEdit();
        adapter.Update(bs.DataSource as DataTable);
    }
