Socket.UseOnlyOverlappedIO Property

Note: This property is new in the .NET Framework version 2.0.

Specifies whether the socket should only use Overlapped I/O mode.

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

public bool UseOnlyOverlappedIO { get; set; }
/** @property */
public boolean get_UseOnlyOverlappedIO ()

/** @property */
public void set_UseOnlyOverlappedIO (boolean value)

public function get UseOnlyOverlappedIO () : boolean

public function set UseOnlyOverlappedIO (value : boolean)

Property Value

true if the Socket uses only overlapped I/O; otherwise, false. The default is false.

Exception typeCondition

InvalidOperationException

The socket has been bound to a completion port.

Set this property to true for a Socket you intend to call DuplicateAndClose. Otherwise, the Framework may assign a completion port to the socket, which would prohibit the use of DuplicateAndClose.
