TimeoutException uses the HRESULT, COR_E_TIMEOUT, which has the value 0x80131505.

For a list of initial property values for an instance of TimeoutException, see the TimeoutException constructors.

The following code example demonstrates the use of TimeoutException in conjunction with members of the System.IO.Ports.SerialPort class.


// This example demonstrates the use of the TimeoutException 
// exception in conjunction with the SerialPort class.

using System;
using System.IO.Ports;

class Sample 
{
    public static void Main() 
    {
    string input;
    try 
        {
// Set the COM1 serial port to speed = 4800 baud, parity = odd, 
// data bits = 8, stop bits = 1.
        SerialPort sp = new SerialPort("COM1", 
                        4800, Parity.Odd, 8, StopBits.One); 
// Timeout after 2 seconds.
        sp.ReadTimeout = 2000;
        sp.Open();

// Read until either the default newline termination string 
// is detected or the read operation times out.
        input = sp.ReadLine();

        sp.Close();

// Echo the input.
        Console.WriteLine(input);
        }

// Only catch timeout exceptions.
    catch (TimeoutException e)
        {
        Console.WriteLine(e);
        }
    }
}
/*
This example produces the following results:

(Data received at the serial port is echoed to the console if the 
read operation completes successfully before the specified timeout period 
expires. Otherwise, a timeout exception like the following is thrown.)

System.TimeoutException: The operation has timed-out.
   at System.IO.Ports.SerialStream.ReadByte(Int32 timeout)
   at System.IO.Ports.SerialPort.ReadOneChar(Int32 timeout)
   at System.IO.Ports.SerialPort.ReadTo(String value)
   at System.IO.Ports.SerialPort.ReadLine()
   at Sample.Main()
