Hello,
Why doesn't the connection attempt wait 15 seconds?
How can I achieve that the client gets up to 15 seconds for a connection?
Socket or TcpClient. Thanks for your help!
//Create IP address and port number;
System.Net.IPAddress ip = IPAddress.Parse(Ipbox.Text);
int port = Convert.ToInt32(PortBox.Text);
IPEndPoint iPEndPoint = new IPEndPoint(ip, port);
//Determine whether you can connect to the server
try
{
//socket.Connect(iPEndPoint);
var result = socket.BeginConnect(iPEndPoint, null, null);
bool success = result.AsyncWaitHandle.WaitOne(15000, true);
if (success)
{
socket.EndConnect(result);
}
else
{
socket.Close();
throw new SocketException(10060); // Connection timed out.
}
@Markus Freitag , Welcome to Microsoft Q&A, based on my search, I find the following link:
Details of AsyncWaitHandle.WaitOne, the client could not wait for 15 seconds because the wait handle may have been signaled previously.
Could you provide the server code to let me have a test?
https://learn.microsoft.com/en-us/answers/questions/1166323/c-tcpclient-tcplistener-full-duplex-communication Sure. You can find the code inside the thread. Form1 - Client and Server. Thanks for your help. The client should be given 15 seconds to connect.
@Markus Freitag, thanks for the feedback, have you considered using Thread.Sleep() method before you connect to the sever?
Like the following code:
Thread.Sleep(15000);
socket.Connect(iPEndPoint);
if(socket.Connected)
{
}
else
{
}
Yes, but it is a bad solution. Is it waiting every time 15 seconds, also the server is available. Do you have another solution?
Did you understand my problem, my requirement? Thanks for a short feedback!
Greetings Markus

You already asked a similar question here. Using BeginConnect is not a recommended approach at all. Using ConnectAsync with an auto-cancelling source as discussed in the other thread solves the problem you are having here.
