我想知道为什么 NetworkStream 中的 while 不立即执行并等待
我有一个服务器程序。 还有一个客户端程序。
服务器是使用 TcpListener 创建的，客户端是使用 TcpClient 创建的。
经过多次实验，下面代码中的while直到客户端程序中执行stream.write()才被执行。
你能说出这是什么原理吗？
while (true) // That's no!
{
Console.WriteLine("waiting connection...");
TcpClient client = server.AcceptTcpClient();
Console.WriteLine("Connected!");
data = null;
NetworkStream stream = client.GetStream();
int i;
// This is while
while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
{
data = Encoding.UTF8.GetString(bytes, 0, i);
Console.WriteLine("Received: {0}", data);
}
Console.WriteLine("This statement is only executed when stream.write() is executed.");
client.Close();
}
I have a server program.
And there is also a client program.
The server was created using TcpListener, and the client was created using TcpClient.
After several experiments, while in the code below is not executed until stream.write() is executed in the client program.
Can you tell by what principle this is?
while (true) // That's no!
{
Console.WriteLine("waiting connection...");
TcpClient client = server.AcceptTcpClient();
Console.WriteLine("Connected!");
data = null;
NetworkStream stream = client.GetStream();
int i;
// This is while
while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
{
data = Encoding.UTF8.GetString(bytes, 0, i);
Console.WriteLine("Received: {0}", data);
}
Console.WriteLine("This statement is only executed when stream.write() is executed.");
client.Close();
}

您指的是哪个
while，外部还是内部？在客户端写入流之前，服务器执行到什么程度？
通过几个断点应该很容易弄清楚。
TcpClient client = server.AcceptTcpClient();将阻塞，直到请求客户端的连接。To which
whileare you referring, the outer or inner one?Up to what point DOES the server execute before the client writes to the stream?
That should be easy to figure out with a few breakpoints.
TcpClient client = server.AcceptTcpClient();will block until a connection from the client is requested.
