unity3d百度语音合成mp3流转换byte[]失败

using (Stream stream = response.GetResponseStream())

        {

            buffer2 = new byte[stream.Length];

            stream.Read(buffer2, 0, buffer2.Length);

}

stream.Length失败

解决方案

1、用unity自带的www类

2、https://bbs.csdn.net/topics/360163784

byte[] result;
byte[] buffer = new byte[4096];

WebRequest wr = WebRequest.Create(someUrl);

using(WebResponse response = wr.GetResponse())
{
   using(Stream responseStream = response.GetResponseStream())
   {
      using(MemoryStream memoryStream = new MemoryStream())
      {
         int count = 0;
         do
         {
            count = responseStream.Read(buffer, 0, buffer.Length);
            memoryStream.Write(buffer, 0, count);

         } while(count != 0);

         result = memoryStream.ToArray();

      }
   }
}
