ListView中的item怎么设置装箱拆箱操作绑定实体类？

Question

ListBox可以直接装箱拆箱实体类。ListView怎么做啊？

info 实体类

装箱
ListViewItem item = new ListViewItem(info.Name, 0);
item.Tag = info.ID;
this.ListView1.Items.Add(item);

拆出来就出错
Info user = this.ListView1.SelectedItem[0] as Info    这里要怎么写？

Answer 1

ListViewItem构造函数第一个传入String，后面是图标项索引。我建议：

1）用一个List<T>填充（比如Info类）。

2）绑定到ListView中。

3）图标指定，可以用ImageIndex设置某个项索引图标。

hello,

你把资料放进ListViewItem.Tag里面，但你取出的时后少了Tag属性，而且你只放info.ID

ListViewItem item = new ListViewItem(info.Name, 0);
item.Tag = info;
this.ListView1.Items.Add(item);

取出

Info user = this.ListView1.SelectedItem[0].Tag as Info

ListView的每个子项都是ListViewItem对象的，你可以间接去构建实体类，例如代码如下：

// 通过获取子项的属性来构建一个Info对象
// 下面采用了对象构造器的方式来构造一个对象
Info user =new Info {Name=this.ListView1.SelectedItem[0].SubItems[0].Text,Tag = this.ListView1.SelectedItem[0].SubItems[1].Text};
