EventRegistrationToken Structure

.NET Framework 4.6 and 4.5

A token that is returned when an event handler is added to a Windows Runtime event. The token is used to remove the event handler from the event at a later time.

Namespace:   System.Runtime.InteropServices.WindowsRuntime
Assembly:  mscorlib (in mscorlib.dll)

public value struct EventRegistrationToken


Returns a value that indicates whether the current object is equal to the specified object. (Overrides ValueType::Equals(Object^).)


Returns the hash code for this instance. (Overrides ValueType::GetHashCode().)


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


Returns the fully qualified type name of this instance.(Inherited from ValueType.)

System_CAPS_puboperatorSystem_CAPS_staticEquality(EventRegistrationToken, EventRegistrationToken)

Indicates whether two EventRegistrationToken instances are equal.

System_CAPS_puboperatorSystem_CAPS_staticInequality(EventRegistrationToken, EventRegistrationToken)

Indicates whether two EventRegistrationToken instances are not equal.

Use the EventRegistrationToken structure only if you use native Windows Runtime techniques to add and remove event handlers for Windows Runtime events. If you use the syntax that is provided by the C# or Visual Basic languages to add and remove event handlers, EventRegistrationToken is an implementation detail handled by the compilers.
