C#中listview的image添加问题和item双击事件

来源：互联网发布：淘宝首页psd模板教程编辑：程序博客网时间：2024/06/14 06:32

添加imagelist控件，把listview里面的largeimagelist属性和smallimagelist属性都设置为添加的imagelist。

可以通过this.imageList1.Images.Add（string key ， Icon icon）来添加带键值的icon，这样就可以通过item.imagekey = key；使动态添加的item获取到对应key值的Icon

<strong><span style="font-size:18px;"></span></strong>

<strong><span style="font-size:18px;">这是一个listview的item双击事件的实例</span></strong>

<strong><span style="font-size:18px;">this.listView1.MouseDoubleClick += new MouseEventHandler(listView1_Item_MouseDoubleClick);</span></strong>

<pre class="csharp" name="code"><strong><span style="font-size:18px;"></span></strong>

<strong><span style="font-size:18px;">private void listView1_Item_MouseDoubleClick(object sender, MouseEventArgs e)        {            //ListViewItem item = (ListViewItem)sender;            if (listView1.SelectedItems.Count > 0)            {                if (MessageBox.Show("确定要下载此App吗?", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) == DialogResult.OK)                {                    if (listView1.SelectedItems[0].Tag is App)                    {                        FolderBrowserDialog fbd = new FolderBrowserDialog();//文件是openfiledialog                        if (fbd.ShowDialog() == DialogResult.OK)                        {                            App app = listView1.SelectedItems[0].Tag as App;                            int idx = app.AppAddress.LastIndexOf('\\');                            if (idx >= 0)                            {                                string path = fbd.SelectedPath + "\\" + app.AppAddress.Substring(idx + 1);                                File.MoveFile(app.AppAddress, path);                                if (File.isSuccess == true)                                {                                    MessageBox.Show("下载成功", "提示", MessageBoxButtons.OK);                                    AddApptoListview2(app);                                }                            }                        }                        //MessageBox.Show(listView1.SelectedItems[0].Text);                                           }                }            }        }</span></strong>
