虽然现在winform开发很少使用微软自带的控件，但其中有一个控件还是不错的，它就是ListView控件。操作系统的文件夹页，就是ListView控件的样子，数据展示包括大图标、小图标、列表、明细等。今天通过一个实例，来展示下这个控件是如何使用的？先看下效果图

这个实例实现了以下功能：

1、数据分组展示
2、行最前面增加了图标
3、整行全部选中
4、数据展示模式可切换

代码部分也不复杂，这里是全部代码的：创建一个Form页面，里面放一个ToolStrip的工具栏和一个ListView控件即可

private void tbtnLoadData_Click(object sender, EventArgs e)
{
    #region 加载ListView控件,分组显示

    this.listview1.Groups.Clear();
    this.listview1.Items.Clear();

    this.listview1.View = View.Details;
    this.listview1.FullRowSelect = true;

    ColumnHeader columnHeader0 = new ColumnHeader();
    columnHeader0.Text = "Title";
    columnHeader0.Width = 250;
    ColumnHeader columnHeader1 = new ColumnHeader();
    columnHeader1.Text = "Author";
    columnHeader1.Width = 150;
    ColumnHeader columnHeader2 = new ColumnHeader();
    columnHeader2.Text = "Year";
    columnHeader2.Width = 50;

    if (this.listview1.Columns.Count < 3)
    {
        this.listview1.Columns.AddRange(new ColumnHeader[] { columnHeader0, columnHeader1, columnHeader2 });
    }

    ListViewGroup group1 = new ListViewGroup("001");
    ListViewGroup group2 = new ListViewGroup("002");

    this.listview1.Groups.Add(group1);
    this.listview1.Groups.Add(group2);

    ListViewItem item0 = new ListViewItem(new string[] { "Programming Windows", "Petzold, Charles", "1998" }, 0, group1);
    ListViewItem item1 = new ListViewItem(new string[] { "Code: The Hidden Language of Computer Hardware and Software", "Petzold, Charles", "2000" }, 0, group1);
    ListViewItem item2 = new ListViewItem(new string[] { "Programming Windows with C#", "Petzold, Charles", "2001" }, 0, group1);
    ListViewItem item3 = new ListViewItem(new string[] { "Coding Techniques for Microsoft Visual Basic .NET", "Connell, John", "2001" }, 1, group2);
    ListViewItem item4 = new ListViewItem(new string[] { "C# for Java Developers", "Jones, Allen & Freeman, Adam", "2002" }, 1, group2);
    ListViewItem item5 = new ListViewItem(new string[] { "Microsoft .NET XML Web Services Step by Step", "Jones, Allen & Freeman, Adam", "2002" }, 1, group2);
    this.listview1.Items.AddRange(new ListViewItem[] { item0, item1, item2, item3, item4, item5 });

    //加上图标
    this.listview1.LargeImageList = this.imageList1;
    this.listview1.SmallImageList = this.imageList1;

    int index = 0;
    foreach(ListViewItem lvi in this.listview1.Items)
    {
        lvi.ImageIndex = index;
        index++;
    }
    #endregion
}

private void tbtnLarge_Click(object sender, EventArgs e)
{
    this.listview1.View = View.LargeIcon;
}

private void tbtnSmall_Click(object sender, EventArgs e)
{
    this.listview1.View = View.SmallIcon;
}

private void tbtnDetail_Click(object sender, EventArgs e)
{
    this.listview1.View = View.Details;
}
