TcpListener.Pending Method

Determines if there are pending connection requests.

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

member Pending : unit -> bool

Return Value

Type: System.Boolean
true if connections are pending; otherwise, false.


The listener has not been started with a call to Start.

This non-blocking method determines if there are any pending connection requests. Because the AcceptSocket and AcceptTcpClient methods block execution until the Start method has queued an incoming connection request, the Pending method can be used to determine if connections are available before attempting to accept them.

The following code example checks the Pending method. If a connection request is waiting to be accepted, then a call to the AcceptTcpClient method is made.

No code example is currently available or this language may not be supported.
