Question

我试图将范围功能集成到我的HttpServer中，但我一直在收到此错误：

类型＆＃39; System.Net.HttpListenerException＆＃39;未处理的异常   发生在System.dll
中
附加信息：I / O操作因中止而中止   线程退出或应用程序请求

我想提一下我的HttpListener是在Thread上运行的，我使用的是BeginGetContext。

有什么想法导致这个错误吗？

if (File.Exists(RequestedFile))
{
    Stream ReadStream = new FileStream(RequestedFile, FileMode.Open, FileAccess.Read);

    //Get Range
    try
    {
         string[] RangeArray = HttpRequest.Headers.GetValues("Range")[0].Replace("bytes=", "").Split('-');
         long.TryParse(RangeArray[0], out StartChunk);
         if (RangeArray[1].Trim().Length > 0)
         {
             long.TryParse(RangeArray[1], out EndChunk);
         }
         if (EndChunk == 0) { EndChunk = (int)ReadStream.Length; }
         ChunkRange = EndChunk - StartChunk;
    }
    catch
    {
         StartChunk = 0;
         EndChunk = ReadStream.Length;
         ChunkRange = EndChunk - StartChunk;
    }

    HttpResponse.ContentType = "video/mp4";
    HttpResponse.ContentLength64 = ChunkRange;

    //Start File Processing
    byte[] Buffer = new byte[ChunkRange];
    ReadStream.Position = StartChunk;
    ReadStream.Read(Buffer, 0, (int)ChunkRange);
    ReadStream.Flush();
    ReadStream.Close();

    //Flush to Response
    HttpResponse.OutputStream.Write(Buffer, 0, Buffer.Length);//error occurs here

    HttpResponse.StatusCode = (int)HttpStatusCode.OK;
    HttpResponse.OutputStream.Flush();

}
else { HttpResponse.StatusCode = (int)HttpStatusCode.NotFound; }

HttpResponse.OutputStream.Close();

更新这似乎是由于Chrome发生的。 Read accepted answer here
