How to map a 1 or 0 in an ASP.Net MVC route segment into a Boolean action method input parameter

阅读更多关于 How to map a 1 or 0 in an ASP.Net MVC route segment into a Boolean action method input parameter

We have some PHP and Javascript apps that call into some ASP.NET MVC endpoints. Let's say we have this endpoint: public ActionResult DoSomething(bool flag) { } I want it to match the value for flag whether I pass in an integer of 1 or 0, or pass in a string of "true" or "false". What part of the framework do I need to implement in order to match that up? The best way to do this is using a custom value provider. While you can do this using a complete custom model binder, that is overkill based on your requirements, and it is much easier simply to implement a custom value provider. For some

MVC Routing Parameter Precedence

I came across a scenario where I had the default MVC Route setup. Like So. routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); Then navigating to a url as such domain/controller/action/1234 On this page I was then navigating to the same page but with different parameters after a certain event. Like so. var id = $(this).data("id"); var url = "@Url.Action("action", "controller", new { area = ""})"; var params = $.param({id: id, vrnsearch: true}); var fullUrl = url += "?" + params; window

Accept comma and dot as decimal separator [duplicate]

阅读更多关于 Accept comma and dot as decimal separator [duplicate]

问题 This question already has an answer here: How to set decimal separators in ASP.NET MVC controllers? 4 answers Model binding in ASP.NET MVC is great, but it follows locale settings.
