How to return a 200 HTTP Status Code from ASP.NET MVC 3 controller

I am writing an application that is accepting POST data from a third party service.

When this data is POSTed I must return a 200 HTTP Status Code.

How can I do this from my controller?

In project root folder I was deleted bin folder then rebuild project again. This worked for me:

D:\C# Projects\my_demo_project\WebApplication1\bin

If you have a custom object that needs to be returned within the Status 200 response, you can pass a custom object as an OkObjectResult:

public IActionResult Get()
    {
        CustomObject customObject = new CustomObject();

        return Ok(customObject);
    }

The way to do this in .NET Core is (at the time of writing) as follows:

public async Task<IActionResult> YourAction(YourModel model)
{
    if (ModelState.IsValid)
    {
        return StatusCode(200);
    }

    return StatusCode(400);
}

The StatusCode method returns a type of StatusCodeResult which implements IActionResult and can thus be used as a return type of your action.

As a refactor, you could improve readability by using a cast of the HTTP status codes enum like:

return StatusCode((int)HttpStatusCode.OK);

Furthermore, you could also use some of the built in result types. For example:

return Ok(); // returns a 200
return BadRequest(ModelState); // returns a 400 with the ModelState as JSON

    [HttpPost]
    public JsonResult ContactAdd(ContactViewModel contactViewModel)
    {
        if (ModelState.IsValid)
        {
            var job = new Job { Contact = new Contact() };

            Mapper.Map(contactViewModel, job);
            Mapper.Map(contactViewModel, job.Contact);

            _db.Jobs.Add(job);

            _db.SaveChanges();

            //you do not even need this line of code,200 is the default for ASP.NET MVC as long as no exceptions were thrown
            //Response.StatusCode = (int)HttpStatusCode.OK;

            return Json(new { jobId = job.JobId });
        }
        else
        {
            Response.StatusCode = (int)HttpStatusCode.BadRequest;
            return Json(new { jobId = -1 });
        }
    }

In your controller you'd return an HttpStatusCodeResult like this...

[HttpPost]
public ActionResult SomeMethod(...your method parameters go here...)
{
   // todo: put your processing code here

   //If not using MVC5
   return new HttpStatusCodeResult(200);

   //If using MVC5
   return new HttpStatusCodeResult(HttpStatusCode.OK);  // OK = 200
}

You can simply set the status code of the response to 200 like the following

public ActionResult SomeMethod(parameters...)
{
   //others code here
   ...      
   Response.StatusCode = 200;
   return YourObject;  
}

200 is just the normal HTTP header for a successful request. If that's all you need, just have the controller return new EmptyResult();
