asp.net ImageMap控件 点击热点播放mp3

[Rumia]

本人新手 最近要做个点读功能的网页
我用一个ImageMap控件来设置热点 代码：
<p>
<asp:ImageMap ID="ImageMap1" runat="server" ImageUrl="~/images/-005.jpg"
onclick="ImageMap1_Click">
<asp:RectangleHotSpot Bottom="154" HotSpotMode="PostBack" Left="224"
Right="442" Top="115" PostBackValue="cot" />
<asp:RectangleHotSpot Bottom="232" HotSpotMode="PostBack" Left="141"
Right="573" Top="199" PostBackValue="u01" />
</asp:ImageMap>
</p>

后台：
一个click事件：
protected void ImageMap1_Click(object sender, ImageMapEventArgs e)
{
switch (e.PostBackValue)
{
case "cot":
//播放"~/sounds/ce3704.mp3" 这里怎么做？
break;
case "u01":
//同样播放对应音频
break;
}
}

我试过system.media.soundplay 不过只能播放wav的样子 报错说：无波形文件
还有
<object classID='clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6' ID='mediaPlayer' height='64' style="margin-right: 6px; width: 360px;">
插入一个播放器 但是我不知道怎么去控制它的播放还有路径设置 按键事件
想找资料没找到
还有：
来自：msdn.microsoft.com/zh-CN/library/ie/gg589489(v=vs.85).aspx#ManagingPlaybackInJavascript
的：
<script type="text/javascript">
// Global variable to track current file name.
var currentFile = "";
function playAudio()//这里 无法响应imagemap点击事件
{
// Check for audio element support.
if (window.HTMLAudioElement) {
try {
var oAudio = document.getElementById('myaudio');
var btn = document.getElementById('play');
var audioURL = document.getElementById('audiofile');

//Skip loading if current file hasn't changed.
if (audioURL.value !== currentFile) {
oAudio.src = audioURL.value;
currentFile = audioURL.value;
}

// Tests the paused attribute and set state.
if (oAudio.paused) {
oAudio.play();
btn.textContent = "Pause";
}
else {
oAudio.pause();
btn.textContent = "Play";
}
}
catch (e) {
// Fail silently but show in F12 developer tools console
if (window.console && console.error("Error:" + e));
}
}
}
</script>

求大神教我该怎么做？

         string lpstrReturnString,
         int uReturnLength,
         int hwndCallback
        );
    }
}

用上述的类方法 在： //取得播放文件属性 debug总是进入 catch { int a; } 快崩溃了 没人救我吗

问题已解决： 利用ImageMap控件设置热点事件获取mp3路径信息 而后处理成JSON字符串 前台页面获取JSON字符串 利用HTML5的<audio>标签进行播放
