在WinCE7上使用C＃播放MP3 [英] Play MP3 using C# on WinCE7

问题描述

大家好

我从
下载了nAudio DLL CodePlex ，并尝试编写代码来播放MP3音频文件！

I downloaded nAudio DLLs from CodePlex , and tryed to write a code to play an MP3 audio file!

我刚刚复制粘贴代码，但它有一个错误，我不知道如何解决！

I just did Copy-Paste the code, but it has an error I don't know how to solve!

这是我复制的代码：

private void btn_Play_Click(object sender, EventArgs e)
        {
            waveOutDevice = new WaveOut();

            audioFileReader = new AudioFileReader("Horrorshow - Thoughtcrime (Doin' My Think).mp3");

            waveOutDevice.Init(audioFileReader);
            waveOutDevice.Play();
        }

        private void btn_Stop_Click(object sender, EventArgs e)
        {
            CloseWaveOut();
        }

        private void CloseWaveOut()
        {
            if (waveOutDevice != null)
            {
                waveOutDevice.Stop();
            }
            if (mainOutputStream != null)
            {                
                audioFileReader.Dispose();
                audioFileReader = null;
            }
            if (waveOutDevice != null)
            {
                waveOutDevice.Dispose();
                waveOutDevice = null;
            }
        }

错误是：

名称' mainOutputStream '在当前上下文中不存在

推荐答案

在我看来这个示例是不完整的或者应该阅读

Looks to me like the example is incomplete OR should read

            if (audioFileReader!= null)
            {                
                audioFileReader.Dispose();
                audioFileReader = null;
            }

您确定NAudio支持CompactFramework吗？ 虽然一些StackOverflow问题指出了这个方向，但我并没有感觉回答者真正理解Windows CE是否参与其中。 而且我从CodePlex获得的关于
紧凑框架的信息也不多。

Are you sure that NAudio supports the CompactFramework?  While some StackOverflow questions point that direction, I didn't get the feeling that the answerer really understood that Windows CE was involved.  And I don't get a lot from CodePlex about Compact Framework either.

我从Compact Framework需要多媒体的极少数情况我编写了一个C ++ DLL来处理令人厌恶的是DirectShow或WMP Active X控件（取决于我的目标平台），然后使用P / Invoke调用我的C ++
DLL。

The rare occasions I have needed multimedia from the Compact Framework I have written a C++ DLL to deal with the abomination that is DirectShow or the WMP Active X control (depended on my target platform) and then used P/Invoke to call my C++ DLL.
