BeginInvoke

Initiate asynchronous .NET delegate call

Syntax

result = BeginInvoke(arg1,...,argN,callback,object)

Description

result = BeginInvoke(arg1,...,argN,callback,object) initiates asynchronous call to a .NET delegate for Microsoft^® .NET Framework applications. You must call EndInvoke to complete the asynchronous call. For information about calling synchronous methods asynchronously, refer to Microsoft .NET documentation.

Note

For applications using .NET Framework 4.0 and higher, including .NET 6 and .NET Core and later versions, use task-based APIs such as System.Threading.Tasks. For more information, see the Microsoft article Task-based asynchronous pattern (TAP) in .NET.

Input Arguments

arg1,...,argN — Input arguments

any valid type

Input arguments 1 through N (if any) required by delegate, specified as any valid type. The type and number of arguments must agree with the delegate signature.

callback — Method

[] (default) | System.AsyncCallback

Method to call when a corresponding asynchronous operation completes, specified as a .NET System.AsyncCallback delegate or [] null value.

object — Delegate

[] (default) | user-defined .NET object

Delegate, specified as a user-defined ,NET object or [] null value.

Output Arguments

result — Progress monitor

System.IAsyncResult

Progress monitor of the asynchronous call, returned as a .NET System.IAsyncResult object. Use result as the input argument to the EndInvoke function.
