访问冲突异常

Question

当使用system.speech.synthesis这样的：

using (_speech) 
{ 
    _speech.SelectVoice("Anne"); 
    _speech.SpeakCompleted += OnSpeakCompleted; 
    _speech.Rate = Convert.ToInt32(Rate); 
    _speech.Volume = Convert.ToInt32(Volume); 
    _speech.SpeakAsync(text); 
} 

我得到这个错误：

System.AccessViolationException was unhandled 
Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

当创建一个不发生错误语音合成器的对象，但使用它时发生。 FX。改变费率，数量等

有没有人有这种问题的解决方案？解？提示？有什么可以帮助解决这个恼人的问题？

Answer 1

只是一个猜测，你打电话给_speech.SpeakAsync（文本）;这意味着您正在使用语音异步，在下一行中通过关闭使用来处理_speech对象。我可以想象这会导致问题。处理结果后，应该抛弃_speech对象。
