Overloads
| InvokeAsync(AsyncEventHandler, Object, EventArgs) |
Invokes asynchronous event handlers, returning a task that completes when all event handlers have been invoked. Each handler is fully executed (including continuations) before the next handler in the list is invoked. |
| InvokeAsync<TEventArgs>(AsyncEventHandler<TEventArgs>, Object, TEventArgs) |
Invokes asynchronous event handlers, returning a task that completes when all event handlers have been invoked. Each handler is fully executed (including continuations) before the next handler in the list is invoked. |
InvokeAsync(AsyncEventHandler, Object, EventArgs)

Public Function InvokeAsync(Of TEventArgs) (handlers As AsyncEventHandler(Of TEventArgs), sender As Object, args As TEventArgs) As TaskType Parameters
- TEventArgs
The type of argument passed to each handler.
Parameters
- handlers
- AsyncEventHandler<TEventArgs>
The event handlers. May be null.
- sender
- Object
The event source.
- args
- TEventArgs
