c#Windwosmedia控件使用探索

c#Windwosmedia控件使用探索收藏
function StorePage(){d=document;t=d.selection?(d.selection.type!='None'?d.selection.createRange().text:''):(d.getSelection?d.getSelection():'');void(keyit=window.open('http://www.365key.com/storeit.aspx?t='+escape(d.title)+'&u='+escape(d.location.href)+'&c='+escape(t),'keyit','scrollbars=no,width=475,height=575,left=75,top=20,status=no,resizable=yes'));keyit.focus();}一直想自己写一个音乐播放器,原来打算用JAVA中的JMF API,后来发现这个JMF实现的播放器有局限,还不如借助C#的空间,利用VisaulStudio2005来开发.先看效果图



控件的使用主要是使用WINDOWS MEDIA的 API,这里只是简单的使用了他的URL属性,该属性是需要播放文件的位置.下面看代码,其中包含了自己写得一个播放列表功能.
