WinFrom开发ComBox的（键值对）数据绑定

下面是一个简单的例子

private void ComBox_Test()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("ID");
            dt.Columns.Add("Value");

            for (int i = 0; i < test.count; i ++)
            {
                DataRow row = dt.NewRow();
                row["ID"] = test[i].id;
                row["Value"] =  test[i].value;
                dt.Rows.Add(row);
            }

            cmb.ValueMember = "ID";
            cmb.DisplayMember = "Value";
        }
