是的,在C#中,BeginReceive
方法可以设置超时时间。为了实现这个功能,您需要使用Socket
类的SetSocketOption
方法来设置SocketOptionName.ReceiveTimeout
选项。以下是一个示例:
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
class Program
{
static void Main(string[] args)
{
IPAddress ipAddress = IPAddress.Parse("127.0.0.1");
int port = 12345;
using (Socket socket = new Socket(ipAddress.AddressFamily, SocketType.Stream, ProtocolType.Tcp))
{
socket.Connect(ipAddress, port);
// 设置接收超时时间(单位:毫秒)
int receiveTimeout = 5000;
socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, receiveTimeout);
byte[] buffer = new byte[1024];
IAsyncResult result = socket.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, null);
// 检查是否在超时时间内接收到数据
if (result.AsyncWaitHandle.WaitOne(receiveTimeout, true))
{
int bytesReceived = socket.EndReceive(result);
string receivedData = https://www.yisu.com/ask/Encoding.UTF8.GetString(buffer, 0, bytesReceived);"Received data: " + receivedData);
}
else
{
Console.WriteLine("Receive operation timed out.");
}
}
}
}
在这个示例中,我们首先创建一个Socket
对象并连接到指定的IP地址和端口。然后,我们使用SetSocketOption
方法设置接收超时时间为5000毫秒(5秒)。接下来,我们使用BeginReceive
方法开始接收数据,并使用AsyncWaitHandle.WaitOne
方法检查是否在超时时间内接收到数据。如果在超时时间内接收到数据,我们使用EndReceive
方法结束接收操作并处理接收到的数据。如果未在超时时间内接收到数据,我们将输出一条超时消息。
