`不是WAVE文件-没有RIFF标头`锁定文件 [英] `Not a WAVE file - no RIFF header` locks file

问题描述

使用代码:

using (var reader = new WaveFileReader(audioFileLocation))
{
    // Do something....
}

如果给出了引发异常的wav文件:

If given a wav file that throws the exception:

不是WAVE文件-没有RIFF标头
异常详细信息:System.FormatException:不是WAVE文件-没有RIFF标头

Not a WAVE file - no RIFF header
Exception Details: System.FormatException: Not a WAVE file - no RIFF header

它锁定文件audioFileLocation，以防止其被删除.

It locks the file audioFileLocation which prevents it from being deleted.

在使用阅读器之前，有什么方法可以检查是否存在有效的RIFF标头?

Is there any way to check for the existence of a valid RIFF header before using the reader?

推荐答案

尝试使用流:

using(var inputStream = new FileStream(audioFileLocation, FileMode.Open, 
                           FileAccess.Write, FileShare.ReadWrite))
{
    using (var reader = new WaveFileReader(inputStream))
    {
        // Do something....
    }
}

如果 THIS 是当前代码在构造器的字符串重载"中使用File.OpenRead(waveFile)的WaveFileReader类，返回的Stream似乎没有被关闭/处置.也许已经是后续作品了:

If THIS is the current code of the WaveFileReader class it uses File.OpenRead(waveFile) in the "string overload" of the consturctor and the Stream returned seems not to be closed/disposed. Maybe already the follownin works:

using(var inputStream = File.OpenRead(audioFileLocation))
{
    using (var reader = new WaveFileReader(inputStream))
    {
        // Do something....
    }
}

因为这应该处理流.
