WinForm实现仿视频播放器左下角滚动新闻效果的方法

本文实例讲述了winform实现仿视频播放器左下角滚动新闻效果的方法。分享给大家供大家参考。具体实现方法如下：

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.linq;
using system.text;
using system.windows.forms;
using system.drawing.imaging;
using system.io;
using system.xml.linq;
namespace app
{
 public partial class form7 : form
 {
  private int index { get; set; }
  private datatable datatable { get; set; }
  private system.timers.timer timer { get; set; }
  public form7()
  {
   initializecomponent();
   datatable = new datatable();
   datatable.columns.addrange(new datacolumn[] { 
    new datacolumn("id",typeof(system.int32)),
    new datacolumn("displayname",typeof(system.string)),
    new datacolumn("url",typeof(system.string))
   });
   datarow row = datatable.newrow();
   row["id"] = 1;
   row["displayname"] = "百度百科欢迎你!";
   row["url"] = "http://www.baidu.com";
   datatable.rows.add(row);
   row = datatable.newrow();
   row["id"] = 2;
   row["displayname"] = "刘xx明星已经现身搜狐网站，赶快去围观!";
   row["url"] = "http://www.sohu.com";
   datatable.rows.add(row);
   row = datatable.newrow();
   row["id"] = 3;
   row["displayname"] = "新浪新闻出现重大新闻，点我快速查看!";
   row["url"] = "http://www.sina.com.cn";
   datatable.rows.add(row);
   row = datatable.newrow();
   row["id"] = 4;
   row["displayname"] = "网易客户端出现新版本啦，赶快去体验把!";
   row["url"] = "http://www.126.com";
   datatable.rows.add(row);
   label1.text = lblcontent.top.tostring();
   timer = new system.timers.timer(2000);
   timer.elapsed += delegate
   {
    charsmouse();
   };
   timer.start();
   button1.click += delegate
   {
    charsmouse();
   };
   button2.click += delegate
   {
    timer.dispose();
   };
   lblcontent.linkclicked += delegate
   {
    label2.text = datatable.rows[index]["url"].tostring();
   };
  }
  void charsmouse()
  {
   this.lblcontent.invoke(new methodinvoker(delegate
   {
    if (index >= datatable.rows.count)
     index = 0;
    while (lblcontent.top > -lblcontent.height)
    {
     lblcontent.top = lblcontent.top - 2;
     label1.text = "1.top=" + lblcontent.top.tostring();
     system.threading.thread.sleep(100);
     application.doevents();
    }
    lblcontent.text = datatable.rows[index]["displayname"].tostring();
    lblcontent.top = 2;
    timer.enabled = false;
    application.doevents();
    system.threading.thread.sleep(2000);
    timer.enabled = true;
    index++;
   }));
  }
 }
}
