xaml

<ListView.ContextMenu>
       <ContextMenu>
             <MenuItem Header="下载" Click="MenuItem_Click" />
             <MenuItem Header="打开" />
       </ContextMenu>
</ListView.ContextMenu>

c# 关于Ftp.FTPHelper,看另有一篇随笔很实用的FTP操作类

private void MenuItem_Click(object sender, RoutedEventArgs e)
        {
            Ftp.FTPHelper("pic", "123456");
            Ftp.DownLoadFile(ftp://192.168.1.1/ + str, "e:\" + str);
            System.Windows.Forms.MessageBox.Show("下载完毕");
        }

 再使用IsEnbled的属性，又一强暴功能
