• 前言

  
  

• 实用小功能

• combobox绑定一个value

• //定义一个datatable 实例化出每一行
              DataTable sourcettable = new DataTable();
              sourcettable.Columns.Add("Name");
              sourcettable.Columns.Add("Code");
              DataRow dr1 = sourcettable.NewRow();
              dr1["Name"] = "节育相关检查";
                          dr1["Code"] = "917";
                          sourcettable.Rows.Add(dr1);
                            comboBox2.DataSource = sourcettable;//设置数据源
                          comboBox2.DisplayMember = "Name";//设置显示列
                          comboBox2.ValueMember = "Code";//设置实际值
                          comboBox2.SelectedIndexChanged += new EventHandler(comboBox2_SelectedIndexChanged);

注意；DataSource 设置过后不能再对combobox2的元素进行更改
现在    comboBox2.SelectedValue.ToString(); 就等于绑定的code
