Syntax

C++

Copy

public class Delay : ProcessableWorkflowChildBase

Public Class Delay
	Inherits ProcessableWorkflowChildBase

public ref class Delay : public ProcessableWorkflowChildBase

type Delay =  
    class
        inherit ProcessableWorkflowChildBase
    end

The Delay type exposes the following members.

Constructors

	Name	Description
	Delay(Int32)	Initializes a new instance of the Delay class.
	Delay(Int32, Action Delay )	Initializes a new instance of the Delay class.

Remarks

This is the recommended mechanism to put a delay into a workflow. Don’t use Thread.Sleep() or any other blocking method to achieve delays. This would block the execution threads of the Engine

Examples

Copy

await new Delay(1000);

Copy

new Delay(1000, delay => { /* Success Handler */} );
