编程TCP服务器时,我想设置从客户端读取请求的超时时间：
var tcpClient = tcpListener.AcceptTcpClient(); var networkStream = tcpListener.GetStream(); tcpClient.ReceiveTimeout = 10000; networkStream.ReadTimeout = 10000;
见最后两行.我应该选择哪一个？它们在有效性方面是否相同,或者它们在哪些方面有所不同？
解决方法
Which one should I prefer?
前者和后者都将其内部Socket设置为接收的超时.同一个套接字将从TcpClient传递到创建的NetworkStream,所以我会选择前者.
Are they equal in terms of effectivity or in which way to they differ?
我们可以看看source code是件好事.
这是TcpClient.ReceiveTimeout：
public int ReceiveTimeout
{
get
{
return numericOption(SocketOptionLevel.Socket,SocketOptionName.ReceiveTimeout);
}
set
{
Client.SetSocketOption(SocketOptionLevel.Socket,SocketOptionName.ReceiveTimeout,value);
}
}
其中设置了underling客户端套接字的接收超时(客户端的类型为Socket).然后传递给NetworkStream：
public NetworkStream GetStream()
{
// Shortened for brevity
if (m_DataStream==null)
{
m_DataStream = new NetworkStream(Client,true);
}
return m_DataStream;
}
当NetworkStream查找超时时,它会查看Socket内部：
public override int ReadTimeout
{
get
{
int timeout = (int)m_StreamSocket.GetSocketOption(SocketOptionLevel.Socket,SocketOptionName.ReceiveTimeout);
if (timeout == 0)
{
return -1;
}
}
return timeout;
}
