Socket.Close Method (Int32)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Closes the Socket connection and releases all associated resources with a specified timeout to allow queued data to be sent.
Namespace: System.Net.Sockets
Assembly: System.Net (in System.Net.dll)
Syntax
'Declaration
Public Sub Close ( _
timeout As Integer _
)
public void Close(
int timeout
)
Parameters
- timeout
Type: System.Int32
The maximum amount of time, in seconds, to wait in order to send any remaining data, and then close the Socket.
Remarks
The Close method closes the remote host connection and releases all managed and unmanaged resources associated with the Socket. Upon closing, the Connected property is set to false.
For connection-oriented protocols, it is recommended that you call Shutdown before calling the Close method. This ensures that all data is sent and received on the connected socket before it is closed.
If you need to call Close without first calling Shutdown, you can ensure that data queued for outgoing transmission will be sent by calling the Close method and specifying a non-zero timeout interval. The Close method will then block until this data is sent or until the specified timeout expires.
A Socket instance cannot be reused.
