winform中combox动态添加项

在Winform中combobox没有象Web的DropDownList那样有个ListItem，

但我们可以自己写一个类

public class ListItem     {         private string _displayMember;         private int _valueMember;           public string DisplayMember         {             get { return _displayMember; }             set { _displayMember = value; }         }                  public int ValueMember         {             get { return _valueMember; }             set { _valueMember = value; }         }           public ListItem(string displayMember,int valueMember)         {             _displayMember = displayMember;             _valueMember = valueMember;         }           ///         /// 显示值用         ///         ///         public override string ToString()         {             return _displayMember;         }

然后调用combobox.Items.Add()方法，如果是数组就为combox.Items.AddRange()方法

combobox.ValueMember = “ValueMember”;

combobox.DisplayMember = “DisplayMember”;

 

取值的时候直接 (combobox.selectItem as ListItem).ValueMember;
