通过tcpserver向客户端发送Mp3文件

Question

我有一个tcp客户端，如下所示：

public static void RunStream()
{
Console.WriteLine("Starting Stream...");
TcpListener listen = new TcpListener(IPAddress.Parse("127.0.0.1"), 13000);
listen.Start();
while (true)
{
Console.Write("Waiting for a connection... ");
Socket socket = listen.AcceptSocket();
if (socket.Connected)
{
SendFile(socket);
socket.Disconnect(false);
}
}
}
public static void SendFile(Socket socket)
{
NetworkStream netstream = new NetworkStream(socket);
StreamWriter writer = new StreamWriter(netstream);
FileStream fileStream = File.Open("file_example_MP3_700KB.mp3", FileMode.Open, FileAccess.Read, FileShare.Read);
fileStream.CopyTo(netstream);
netstream.Flush();
netstream.Close();
}
static void Main(string[] args)
{
RunStream();
}

以及一个从服务器读取并保存流(包含mp3文件(的客户端，如下所示：

static void Main(string[] args)
{

TcpClient client = new TcpClient("127.0.0.1", 13000);

byte[] bytes = new byte[2100000];
var stream = client.GetStream();
int i;
while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
{
stream.Write(bytes, 0, i);
}
File.WriteAllBytes("test.mp3", bytes);
stream.Flush();
client.Close();           
}

问题是我只得到了原始mp3的一个片段，例如，如果原始文件的持续时间为24秒，我只得到第一个5-8的

bro在客户端中您编写了stream.Read(bytes, 0, bytes.Length)，这意味着您每次读取数据时都要重写数组
并且您使用大数组来保存数据，如果您发送大文件，这将产生问题
它的更好代码如下bro:

static void Main(string[] args)
{
TcpClient client = new TcpClient("127.0.0.1", 13000);
var stream = client.GetStream();
byte[] buff = new byte[1024]; //you can change length later, bigger arrays have more reading speed but give more ram
FileStream filestream = new FileStream("test.mp3", FileMode.Create);
while (stream.Length > stream.Position)
{
int readLength = stream.Read(buff, 0, buff.Length);
filestream.Write(buff, 0, readLength);
}
stream.Flush();
client.Close();
}
