NetworkStream.ReadTimeout Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

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

Namespace:   System.Net.Sockets
Assembly:  System (in System.dll)

public override int ReadTimeout { get; set; }

Property Value

Type: System.Int32

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

Exception Condition

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

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


This property affects only synchronous reads performed by calling the Read method. This property does not affect asynchronous reads performed by calling the BeginRead method.

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

// Create a client that will connect to a 
         // server listening on the contosoServer computer
         // at port 11000.
         TcpClient tcpClient = new TcpClient();
         tcpClient.Connect("contosoServer", 11000);
         // Get the stream used to read the message sent by the server.
         NetworkStream networkStream = tcpClient.GetStream();
         // Set a 10 millisecond timeout for reading.
         networkStream.ReadTimeout = 10;
         // Read the server message into a byte buffer.
         byte[] bytes = new byte[1024];
         networkStream.Read(bytes, 0, 1024);
         //Convert the server's message into a string and display it.
         string data = Encoding.UTF8.GetString(bytes);
         Console.WriteLine("Server sent message: {0}", data);
