NetworkStream.WriteTimeout Property

Definition

Gets or sets the amount of time that a write operation blocks waiting for data.

public:
 virtual property int WriteTimeout { int get(); void set(int value); };
public override int WriteTimeout { get; set; }
member this.WriteTimeout : int with get, set
Public Overrides Property WriteTimeout As Integer

Property Value

A Int32 that specifies the amount of time, in milliseconds, that will elapse before a write operation fails. The default value, Infinite, specifies that the write operation does not time out.

Exceptions

The value specified is less than or equal to zero and is not Infinite.

Examples

The following code example sets the write time-out for a network stream to 10 milliseconds.

#using <System.dll>
using namespace System;
using namespace System::Text;
using namespace System::Net;
using namespace System::Net::Sockets;

int main()
{
    // Create the server side connection and
    // start listening for clients.
    TcpListener^ tcpListener = gcnew TcpListener(IPAddress::Any, 11000);
    tcpListener->Start();
    Console::WriteLine("Waiting for a connection....");

    // Accept the pending client connection.
    TcpClient^ tcpClient = tcpListener->AcceptTcpClient();
    Console::WriteLine("Connection accepted.");
    // Get the stream to write the message
    // that will be sent to the client.
    NetworkStream^ networkStream = tcpClient->GetStream();
    String^ responseString = "Hello.";
    // Set the write timeout to 10 millseconds.
    networkStream->WriteTimeout = 10;
    // Convert the message to a byte array and sent it to the client.
    array<Byte>^ sendBytes = Encoding::UTF8->GetBytes(responseString);
    networkStream->Write(sendBytes, 0, sendBytes->Length);
    Console::WriteLine("Message Sent.");
    // Close the connection to the client.
    tcpClient->Close();
    // Stop listening for incoming connections
    // and close the server.
    tcpListener->Stop();

    // Dispose allocated resources.
    delete networkStream;
    delete tcpClient;
}
using System;
using System.Text;
using System.Net;
using System.Net.Sockets;

namespace Examples.System.Net
{
    public class TCPListenerExample
    {
        public static void Main()
        {
            // Create the server side connection and
            // start listening for clients.
            TcpListener tcpListener = new TcpListener(IPAddress.Any,11000);
            tcpListener.Start();
            Console.WriteLine("Waiting for a connection....");

            // Accept the pending client connection.
            using TcpClient tcpClient = tcpListener.AcceptTcpClient();
            Console.WriteLine("Connection accepted.");
            // Get the stream to write the message
            // that will be sent to the client.
            using NetworkStream networkStream = tcpClient.GetStream();
            string responseString = "Hello.";
            // Set the write timeout to 10 millseconds.
            networkStream.WriteTimeout = 10;
            // Convert the message to a byte array and sent it to the client.
            Byte[] sendBytes = Encoding.UTF8.GetBytes(responseString);
            networkStream.Write(sendBytes, 0, sendBytes.Length);
            Console.WriteLine("Message Sent.");
            // Close the connection to the client.
            tcpClient.Close();
            // Stop listening for incoming connections
            // and close the server.
            tcpListener.Stop();
        }
    }
}

Remarks

If the write operation does not complete within the time specified by this property, the write operation throws a IOException.

Note

This property affects only synchronous write operations performed by calling the Write method. This property does not affect asynchronous writes performed by calling the BeginWrite or WriteAsync method.
