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：
usingSystem;
usingSystem.Collections.Generic;
usingSystem.ComponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Linq;
usingSystem.Text;
usingSystem.Windows.Forms;
usingSystem.Drawing.Imaging;
usingSystem.IO;
usingSystem.Xml.Linq;
namespaceApp
{
publicpartialclassForm7:Form
{
privateintIndex{get;set;}
privateDataTabledataTable{get;set;}
privateSystem.Timers.Timertimer{get;set;}
publicForm7()
{
InitializeComponent();
dataTable=newDataTable();
dataTable.Columns.AddRange(newDataColumn[]{
newDataColumn("Id",typeof(System.Int32)),
newDataColumn("DisplayName",typeof(System.String)),
newDataColumn("URL",typeof(System.String))
});
DataRowrow=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=newSystem.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();
};
}
voidCharsMouse()
{
this.lblContent.Invoke(newMethodInvoker(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。
