The following example shows the function definition after adding a Queue Storage output binding to an HTTP triggered function:
::: zone pivot="programming-language-csharp"

Isolated process

Because an HTTP triggered function also returns an HTTP response, the function returns a MultiResponse object, which represents both the HTTP and queue output.

[Function("HttpExample")]
public static MultiResponse Run([HttpTrigger(AuthorizationLevel.Function, "get", "post")] HttpRequest req,
    FunctionContext executionContext)
{

This example is the definition of the MultiResponse object that includes the output binding:

public class MultiResponse
{
    [QueueOutput("outqueue",Connection = "AzureWebJobsStorage")]
    public string[] Messages { get; set; }
    public IActionResult HttpResponse { get; set; }
}

When applying that example to your own project, you might need to change HttpRequest to HttpRequestData and IActionResult to HttpResponseData, depending on if you are using ASP.NET Core integration or not.

Messages are sent to the queue when the function completes. The way you define the output binding depends on your process model. For more information, including links to example binding code that you can refer to, see Add bindings to a function.
