.NET Events and Delegates in MATLAB

R2026b

Use .NET event callbacks, create and call .NET delegates

A delegate is a way to tell C# which method to call when an event is triggered. An event is a notification by .NET that an action has occurred. These topics show how to use .NET events and delegates in MATLAB^®.

Functions

`BeginInvoke`	Initiate asynchronous .NET delegate call
`EndInvoke`	Retrieve result of asynchronous call initiated by .NET `System.Delegate` `BeginInvoke` method
`Combine`	Static .NET `System.Delegate` `Combine` method
`Remove`	Static .NET `System.Delegate` `Remove` method
`RemoveAll`	Static .NET `System.Delegate` `RemoveAll` method
