En mi ASP.NET aplicación MVC, tengo una vista que se llama Html.Action("MyAction", this.Model) - Tengo una situación similar en un controlador diferente y funciona bien, pero en este caso, se rompe.I establecer un punto de interrupción en la primera línea de MyAction, pero es que no se rompen, por lo que el error debe ocurrir antes de que el punto en el código.

¿Cómo puedo llegar desde este seguimiento de la pila para averiguar el código de mi aplicación que hace que la excepción?
Solución
Este problema en particular es:
System.Web.HttpException:El servidor no puede establecer el estado después de que se hayan enviado los encabezados HTTP.
en System.Web.HttpResponse.set_StatusCode (valor Int32)
en System.Web.HttpResponseWrapper.set_StatusCode (valor Int32)
en Cobalt.Website.Platform.Web.Controllers.Controller.OnException(ExceptionContext filterContext) en D:\data\Website\App\Website\Controllers\Controller.cs:línea 920
Su controlador de excepciones está intentando establecer el código de estado de respuesta después de que el servidor haya comenzado a generar el contenido de la página.Deberías probar/captar el conjunto StatusCode, supongo, y poner un punto de interrupción en el código OnException para ver cuál es la excepción real, aunque parece ser de
d:\datos\Sitio web\Aplicación\Sitio web\Buscar\Vistas\SearchResults.aspx:línea 39
De paso Html.Action genera la URL que desencadena una acción particular y no llama a la acción en sí.Querías decir Html.RenderAcción?Sin embargo, no estoy seguro de que pasar el modelo sea correcto; ¿es poco probable que tenga los valores de ruta tal como están?
Otros consejos
Pude deshacerme de esto devolviendo una vista () en la acción que no sea volver a ejecutar RedirectToAction("SomeAction");
