贴两段代码

因为没有找到如何在ComboBox和ListBox中的item附加tag的办法，所以自己添加了一下。主要是试验一下如何用博客园新加的代码高亮这个酷酷的功能：

public   class  FlexComboBox : System.Windows.Forms.ComboBox
     {
        private System.Collections.ArrayList ItemValues = new System.Collections.ArrayList();
        public void FlexAddItem(string itemText, object itemValue)
        {
            this.Items.Add(itemText);
            ItemValues.Add(itemValue);
        }
        public object FlexGetSelectedItemValue()
        {
            return ItemValues[this.SelectedIndex];
        }
        public void FlexClearItems()
        {
            ItemValues.Clear();
            this.Items.Clear();
        }
    }

public   class  FlexListBox : System.Windows.Forms.ListBox
     {
        private ArrayList itemValues = new ArrayList();
        public FlexListBox() { }

        public void FlexAddItem(string itemText, object itemValue)
        {
            this.Items.Add(itemText);
            itemValues.Add(itemValue);
        }
        public void FlexRemoveSelectedItems()
        {
            for(int i=0;i<this.SelectedIndices.Count;i++)
            {
                int index = this.SelectedIndices[i];
                this.Items.RemoveAt(index);
                itemValues.RemoveAt(index);
            }
        }
        public void FlexClearItems()
        {
            itemValues.Clear();
            this.Items.Clear();
        }
        public ArrayList FlexGetItemValues()
        {
            return itemValues;
        }
        public object FlexGetSelectedValue()
        {
            return itemValues[this.SelectedIndex];
        }
    }
