  In my api controller action method. I am using ContentNegotation for Get Request. the code is :

  IContentNegotiator negotiator = this.Configuration.Services.GetContentNegotiator();
  ContentNegotiationResult result = negotiator.Negotiate(typeof(OfficeDetailsDto), this.Request, this.Configuration.Formatters);
  if (result == null)
  {
  var responseErr = new HttpResponseMessage(HttpStatusCode.NotAcceptable);
  throw new HttpResponseException(responseErr);
  }

  But now I want to create a BaseAPIController controller by inheriting ApiController and want to override a base class's method to have the above code so that I don't have to write this code again and again in my every controller class. It will also make my controller action method thin.

  Can anyone give me any suggestion or sample please.

  Hi Neo,

  You can use Action Fiters for that. Read below for more.

  public class MyActionFilter : ActionFilterAttribute
  {
  	public override void OnActionExecuting(HttpActionContext actionContext)
  	{
  	   //....
  	}
  
  	public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
  	{
  	   //....
  	}
  }
  
  [MyActionFilter]
  public IEnumerable<string> Get()
  {
  	return new string[] { "value1", "value2" };
  }
