Question

我正在尝试在C＃中创建一个简单的控制台应用程序。我需要制作流媒体视频，必须直接从浏览器访问。

我正在审核链接Streaming large video files .net，但似乎此代码适用于asp.net

我尝试的另一件事是TCPCliente，但在发送大文件时遇到了问题。

var fs = File.Open("../../video.mp4", FileMode.Open);

outHeaders.Add("Content-Type", "video/mp4");
outHeaders.Add("Accept-Ranges", "0-" + fs.Length);

long size = fs.Length;
long length = size;
long startBytes = 0;
long endBytes = size - 1;

if (headers["Range"] != null)
{
    var msg = System.Text.Encoding.ASCII.GetBytes("HTTP/1.0 206 Partial Content" + "\n");
    stream.Write(msg, 0, msg.Length);

    var range = ParseRange(size, headers["Range"].ToString());

    startBytes = range.Start;
    endBytes = range.End;

    fs.Seek(startBytes, SeekOrigin.Begin);
    length = endBytes - startBytes + 1;
}
else
{
    var msg = System.Text.Encoding.ASCII.GetBytes("HTTP/1.0 200 OK" + "\n");
    stream.Write(msg, 0, msg.Length);
}

outHeaders.Add("Content-Length", length);
outHeaders.Add("Content-Range", string.Format("bytes {0}-{1}/{2}", startBytes, endBytes, size));

SendHeader(stream, outHeaders);

int bytesRead = 0;
byte[] buf = new byte[client.SendBufferSize];
while (fs.Position <= endBytes && 
    (bytesRead = fs.Read(buf, 0, buf.Length)) > 0)
{
    stream.Write(buf, 0, bytesRead);
    stream.Flush();
}

fs.Close();

问题在于：

while (fs.Position <= endBytes && 
    (bytesRead = fs.Read(buf, 0, buf.Length)) > 0)
{
    stream.Write(buf, 0, bytesRead);
    stream.Flush();
}

当fs.Position = 425984时，我收到错误：

在stream.Write(buf, 0, bytesRead);行

我该怎么办？ THX
