| Name | Description | |
|---|---|---|
![]() | Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception.(Inherited from Exception.) |

![]() | StackTrace | Gets a string representation of the immediate frames on the call stack.(Inherited from Exception.) |
![]() | TargetSite | Gets the method that throws the current exception.(Inherited from Exception.) |
| Name | Description | |
|---|---|---|
![]() | Equals(Object^) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.) |
![]() | GetBaseException() | |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetObjectData(SerializationInfo^, StreamingContext) | When overridden in a derived class, sets the SerializationInfo with information about the exception.(Inherited from Exception.) |
![]() | GetType() | Gets the runtime type of the current instance.(Inherited from Exception.) |
![]() | MemberwiseClone() | |
![]() | ToString() | Creates and returns a string representation of the current exception.(Inherited from Exception.) |
| Name | Description | |
|---|---|---|
![]() | SerializeObjectState | Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.) |
For information about setting the time-out interval before a TimeoutException exception is thrown, consult the documentation for the type whose method timed out. For information about handling the time-out, see the documentation for the method that threw the exception.
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.dll> using namespace System; using namespace System::IO::Ports; int main() { String^ input; try { // Set the COM1 serial port to speed = 4800 baud, parity = odd, // data bits = 8, stop bits = 1. SerialPort^ port = gcnew SerialPort("COM1", 4800, Parity::Odd, 8, StopBits::One); // Timeout after 2 seconds. port->ReadTimeout = 2000; port->Open(); // Read until either the default newline termination string // is detected or the read operation times out. input = port->ReadLine(); port->Close(); // Echo the input. Console::WriteLine(input); } // Only catch timeout exceptions. catch (TimeoutException^ ex) { Console::WriteLine(ex); } }; /* 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() */
