        {
            // 创建数据库连接对象
            connection = new SqlConnection("YourConnectionString");

            // 创建数据库命令对象
            SqlCommand command = new SqlCommand("SELECT * FROM YourTable", connection);

            // 创建数据适配器对象
            dataAdapter = new SqlDataAdapter(command);

            // 创建数据集对象
            dataSet = new DataSet();

            // 执行查询命令并将结果存储在数据集中
            dataAdapter.Fill(dataSet, "YourTable");

            // 将数据集中的数据绑定到DataGridView组合框
            dataGridView.DataSource = dataSet.Tables["YourTable"];

            // 设置DataGridView组合框的显示列
            dataGridView.DisplayMember = "YourColumnName";
        }
    }
