如何调用异步控制器并返回Task <IHttpActionResult> 直接在C＃中

Question

I'm trying to get the results of an action from a controller directly without doing an http request

right now instantiating the controller and calling the method trying to add the results to some item which is in an diferent type

// other file 
_params.Id = item.Id;
var Presponse = new ProductsController().GetProducts(_params);
item.p = Presponse;

//controller file
public class ProductsController : ApiController
{
    [HttpPost]
    [Route("products")]
    [Compress]
    // controller method signature
    public async Task<IHttpActionResult> GetProducts(TheParams model){ 
       .... some logic ....
       Ok(results) 
    }
}

It says I can't implicitly convert the type, in my case to a DTO class I have, I'm expecting to get the value of the response (object) just like an HTTP Request but directly and cast it.

// You could use await if your method is async, for simplicity just Result.
  IHttpActionResult actionResult = new ProductsController().GetProducts(_params).Result;

// if your result is a Product Type
  var contentResult = actionResult as OkNegotiatedContentResult<Product>;
  Product product = contentResult.Content;

// Map to your DTO class for example
   ProductDto dto = new ProductDto()
   {
        Id = product.Id,
        Name = product.Name
    };
