在线等 C#socket文件传输

Question

我晚上写了一个文件传输，比较简单。分发送方和接收方。在本机上测试之后，确实可以收到文件，但是会一直接收数据，导致获得的文件变得异常的大。请大家赐教，本人新手，可能写的地方有错误，请指出。谢谢。
//接收方代码。我把名称空间都删了，怕字数过多，发不了贴。

Answer 1

发文件之前先把长度发过来，收到了这么多长度之后就直接写到文件里面去就行了。
socket程序当然会一直接接收，没有数据到达的话，接收的线程会阻塞。

Answer 2

int count = ne.Read(re, 0, re.Length);
  while (count!=0)
  {
  fi.Write(re, 0, re.Length);
  //ne.Read(re, 0, re.Length);
改：
int count = ne.Read(re, 0, re.Length);
  
  }
count永远不会为0啊。。

Answer 3

int readLength = 0;
while ((readLength = response.Read(buffer, 0, buffer.Length)) > 0) {
fs.Write(buffer, 0, readLength);
}

Answer 4

while(ne.DataAvailable){//是否还有可读数据}
