在网上找的，还不错，支持很多格式。只需要在页面放个lable，建一个放视频文件的文件夹movie，加入代码：
protected void Page_Load(object sender, EventArgs e)
{
this.Label1.Text = Play("movie/1.wmv",500,400);
}
public string Play(string url, int width, int height)
{
string strTmp = url.ToLower();
if (strTmp.EndsWith(".wmv") || strTmp.EndsWith(".mp3") || strTmp.EndsWith(".wma") || strTmp.EndsWith(".avi") || strTmp.EndsWith(".asf") || strTmp.EndsWith(".mpg"))
{
return wmv(url, width, height);
}
else if (strTmp.EndsWith(".mp3"))
{
return mp3(url, width, height);
}
else if (strTmp.EndsWith(".swf"))
{
return swf(url, width, height);
}
else if (strTmp.EndsWith(".jpg") || strTmp.EndsWith(".gif"))
{
return img(url, width, height);
}
else if (strTmp.EndsWith(".rm"))
{
return rm(url, width, height);
}
else if (strTmp.EndsWith(".rmvb"))
{
return rmvb(url, width, height);
}
else
{
return "数据错误";
}
}
