推荐答案

创建一个类来保存与之关联的值和值..你可以稍后检索它。

create a class to save a value and value associated with it.. and you can retrieve it later.

class ComboItem
       {
           public string Name;
           public int ID;
           public ComboItem(string Name, int value)
           {
               this.Name = Name;
               this.ID = value;
           }
           public override string ToString()
           {
               return this.Name;
           }
       }
