MulticastDelegate Class
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Represents a multicast delegate; that is, a delegate that can have more than one element in its invocation list.
Assembly: mscorlib (in mscorlib.dll)
The MulticastDelegate type exposes the following members.
| Name | Description | |
|---|---|---|
 | CombineImpl | Combines this Delegate with the specified Delegate to form a new delegate. (Overrides Delegate::CombineImpl(Delegate).) |
 | DynamicInvoke | Dynamically invokes (late-bound) the method represented by the current delegate. (Inherited from Delegate.) |
| Equals | Determines whether this multicast delegate and the specified object are equal. (Overrides Delegate::Equals(Object).) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Returns the hash code for this instance. (Overrides Delegate::GetHashCode().) |
| GetInvocationList | Returns the invocation list of this multicast delegate, in invocation order. (Overrides Delegate::GetInvocationList().) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| RemoveImpl | Removes an element from the invocation list of this MulticastDelegate that is equal to the specified delegate. (Overrides Delegate::RemoveImpl(Delegate).) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
  | Equality | Determines whether two MulticastDelegate objects are equal. |
| Inequality | Determines whether two MulticastDelegate objects are not equal. |
| Name | Description | |
|---|---|---|
 | GetMethodInfo | Gets an object that represents the method represented by the specified delegate. (Defined by RuntimeReflectionExtensions.) |
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.
Using delegates to make asynchronous method calls is not supported. Calling BeginInvoke causes a NotSupportedException.
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 the MulticastDelegate class.
