这可能吗？有什么想法吗？关闭while循环中的响应流。这将关闭连接并中断传出流 考虑以下情况：
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader(...))
HttpContext.Current.Response.ContentType = "audio/x-wav";
...
while ((line = reader.ReadLine()) != null)
{
...
HttpContext.Current.Response.BinaryWrite(pcmData);
HttpContext.Current.Response.Flush();
}
HttpContext.Current.Response.End();
