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++;
  }));
 }
}
}

希望本文所述对大家的C#程序设计有所帮助。
