Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets a value that indicates whether a Socket is connected to a remote host as of the last operation.

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


Public ReadOnly Property Connected As Boolean
public bool Connected { get; }

Property Value

Type: System.Boolean
true if the Socket was connected to a remote resource as of the most recent operation; otherwise, false.


The Connected property gets the connection state of the Socket as of the last I/O operation. When it returns false, the Socket was either never connected, or is no longer connected.

The value of the Connected property reflects the state of the connection as of the most recent operation. The last ConnectAsync, ReceiveAsync, or SendAsync operation determines the current state. If you need to determine the current state of the connection, make a zero-byte SendAsync call. If the call completes successfully, then the socket is still connected; otherwise, the socket is no longer connected.
