MulticastDelegate Class

Represents a multicast delegate; that is, a delegate that can have more than one element in its invocation list.

System.Object
  System.Delegate
    System.MulticastDelegate

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

[<AbstractClass>]
[<SerializableAttribute>]
[<ComVisibleAttribute(true)>]
type MulticastDelegate =  
    class 
        inherit Delegate 
    end

The MulticastDelegate type exposes the following members.

  NameDescription
Protected methodMulticastDelegate(Object, String)Initializes a new instance of the MulticastDelegate class.

MulticastDelegate is a special class. Compilers and other tools can derive from this class, but you cannot derive from it explicitly. The same is true of the Delegate class.

In addition to the methods that delegate types inherit from MulticastDelegate, the common language runtime provides two special methods: BeginInvoke and EndInvoke. For more information about these methods, see Calling Synchronous Methods Asynchronously.

A MulticastDelegate has a linked list of delegates, called an invocation list, consisting of one or more elements. When a multicast delegate is invoked, the delegates in the invocation list are called synchronously in the order in which they appear. If an error occurs during execution of the list then an exception is thrown.

The following example demonstrates the use of a class that is derived from MulticastDelegate.
