C＃套接字重构（数据发送）

Question

想象一下，Byte[] refArchiveData大小约为30-100兆字节。我想用NetworkStream stream对象将其发送到服务器：

  TcpClient client = new TcpClient(server, port); 

      Byte[] refLengthBytes = new Byte[4]; 
      Byte[] refArchiveData = null; 

      refArchiveData = File.ReadAllBytes("C:/Temp/Python25.zip"); 

      Console.WriteLine("Archive data length is {0}", refArchiveData.Length); 

      NetworkStream stream = client.GetStream(); 

      refLengthBytes = System.BitConverter.GetBytes(refArchiveData.Length); 

      stream.Write(refLengthBytes, 0, 4); 

      stream.Write(refArchiveData, 0, refArchiveData.Length); 

      stream.Close(); 

      client.Close(); 

如何在这里我把我的档案我必须修改的代码的一部分？也许分裂256-512字节块？

谢谢你的任何建议！

使用Stream.CopyTo方法。这样你就不必将整个文件加载到一个数组中（进入内存）。

using (var file = File.OpenRead("<path to file>")) 
using (var client = new TcpClient("<server>", <port>)) 
using (var netStream = client.GetStream()) 
{ 
    ... 
    file.CopyTo(netStream); 
    ... 
}
