System_CAPS_pubmethodEquals(SessionChangeDescription)

Determines whether the specified session change description is equal to the current session change description.

System_CAPS_pubmethodGetHashCode()

Gets a hash code for the current session change description.(Overrides ValueType.GetHashCode().)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodToString()

System_CAPS_puboperatorSystem_CAPS_staticInequality(SessionChangeDescription, SessionChangeDescription)

Returns a value indicating whether two SessionChangeDescription structures are not equal.

The following code example shows the use of the SessionChangeDescription class in an implementation of the OnSessionChange method in a class derived from ServiceBase. This code example is part of a larger example provided for the ServiceBase class.

        // Handle a session change notice
        protected override void OnSessionChange(SessionChangeDescription changeDescription)

                " - Session change notice received: " +
                changeDescription.Reason.ToString() + "  Session ID: " +
                changeDescription.SessionId.ToString());
#endif
