StateChange event

Public Event StateChange As StateChangeEventHandler

public event override StateChangeEventHandler StateChange;

To process state change messages, you must create a System.Data.StateChangeEventHandler delegate and attach it to this event.

System.Data.StateChangeEventHandler

The following code defines a state change event handler.

' Visual Basic
Private Sub MyStateHandler( _
    obj As Object, args As StateChangeEventArgs _
)
    System.Console.WriteLine( _
        "StateHandler: " + args.OriginalState + " to " _
        + args.CurrentState _
    )
End Sub

The following code is the C# language equivalent:

// C#
private void MyStateHandler(
    object obj, StateChangeEventArgs args
)
{
    System.Console.WriteLine(
        "StateHandler: " + args.OriginalState + " to "
        + args.CurrentState
    );
}

The following code adds the MyStateHandler to the connection named conn.

' Visual Basic
AddHandler conn.StateChange, AddressOf MyStateHandler

The following code is the C# language equivalent:

// C#
conn.StateChange += new StateChangeEventHandler(MyStateHandler);
