c# - Intercept webapi json formatting errors -

-

I exception occurs when you have a way to send intercept distorted json a WebAPI endpoint want, so that I can return to resist a meaningful error codes as only 500 (for example, "go to your broken JSON fix or hell") are

You can create your custom accreditation filter attribute by getting: 

  Public class ValidationFilterAttribute: ActionFilterAttribute {Public Override Zero OnActionExecuting (HttpActionContext actionContext) {if (actionContext.ModelState. Iframe} {actionContext.Response = actionContext .equest .CreateErrorResponse (HttpStatusCode.BadRequest, actionContext.ModelState); }}}

Now, you are either with it can decorate your actions: 

  [HttpGet] [ValidationFilter ()] public string DoSomethingCool ()

or it through your config : 

  config.Filters.Add (new ValidationFilterAttribute ());

c# - WPF Expander overlay used in ItemsControl -

-
I've been searching for a while, but all the solutions I can only deal with parts of my issue. With an item control, which includes the expansion, upon expansion, the content of the extensioner should be shown as an item which is overlapping the other item in the item control and not taking them down. The following XAML-code is actually a big problem: the content of the expansion does not overlap other objects but is hidden behind them, I think it is because of ZIndex because the following in ItemsControl Items are added after expander content. I managed to set a single spreader's ZIndex 99 style triggers, but it appears to be very complicated and error-prone solution any thoughts? & lt; Window x: orbit = "wpfTest.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/winfx/2006/ Xaml "title =" main window "height =" 350 "width =" 525 "...
