列表控件数据操作辅助类

在使用 listbox,checklistbox 时,取出的值总想要自己定义的任意对象,同时可以方便的操作listbox,checklistbox,所以写了这个辅助类 HlListView

使用方法

 1.设置listbox,checklistb值

             ArrayList list =new ArrayList();
             testData tmp1 = new testData("测试数据类1", 10);
             testData tmp2 = new testData("测试数据类2", 2);
             testData tmp3 = new testData("测试数据类3", 5);
             list.Add(tmp1);
             list.Add(tmp2);
             list.Add(tmp3);
             HlListView.setValue(this.listBox2,list,"Name","Age");
             HlListView.setValue(this.checkedListBox2, list, "Name","Age");

2.获得listbox,checklistbox值

               //获得listbox值
             Object value = HlListView.getSelectValue(this.listBox2);
            if ( value != null)...{
                Console.WriteLine("name ="+  ((testData) value).Name );
            }
            //获得checklistbox值
            Object[] values = HlListView.getCheckedValues(this.checkedListBox2);
            if (values != null) ...{
                for (int i = 0; i < values.Length; i++) ...{
                    Console.WriteLine("checkselect="+i+",name =" + ((testData)values[i]).Name);
                }
            }
