[转]c#(winform) 中 ComboBox ListBox 添加项完全解决

首先添加类ListItem：
 /// <summary>
 /// 选择项类，用于ComboBox或者ListBox添加项
 /// </summary>
 public class ListItem
 {
  private string id = string.Empty;
  private string name = string.Empty;
  public ListItem(string sid, string sname)
  {
   id = sid;
   name = sname;
  }
  public override string ToString()  
  {  
   return this.name;
  }
  public string ID
  {
   get
   {
    return this.id;
   }
   set
   {
    this.id = value;
   }
  }
  public string Name
  {
   get
   {
    return this.name;
   }
   set
   {
    this.name = value;
   }
  }
 }

然后在程序中使用：
ListItem item = new ListItem("我是值", "我是名字");
this.lbChoiceRoom.Items.Add(item);
this.lbChoiceRoom.DisplayMember = "Name";
this.lbChoiceRoom.ValueMember = "ID";
