由 拥有回忆 提交于 2019-12-08 15:01:16
问题 I'm trying to POST JSON data to a Web Api method but the JSON data is not binding to the model. Here's my model: [DataContract] public class RegisterDataModel { [DataMember(IsRequired = true)] public String SiteKey { get; set; } [DataMember(IsRequired = true)] public String UserId { get; set; } [DataMember(IsRequired = true)] public String UserName { get; set; } } Here's my Web Api action: public class RegisterController : ApiController { public Guid Post([ModelBinder] RegisterDataModel

ASP.NET MVC Session

由 我的未来我决定 提交于 2019-12-08 09:54:22
问题 I've been reading PRO ASP.NET MVC2 by Steven Sanderson and I still can't figure out something about session. In the book he tells how to develop a Cart based on session using a Custom model binder for session persisting. Everything works fine but I can't figure out how it really works under the hood. Since it's a fair amount of code I'll write a simplified version Counter public class Counter { public int counter = 0; public void Increment(){ counter++; } } CounterController public

ASP.net MVC - Use Model Binder without query string values or fancy routes

由 孤街浪徒 提交于 2019-12-08 00:57:21
问题 I have an Asp.net MVC app that currently works well using the default model binder and urls with complex parameters like this: example.com/Controller/Action?a=hello&b=world&c=1&d=2&e=3 (notice the question mark) The different urls automatically map to Action Method parameters using the built in model binder. I would like to continue using the standard model binder but I need to get rid of the query string. We want to put these urls behind a CDN that does not support resources that vary by

Model Binding within a Model Binder

由 柔情痞子 提交于 2019-12-06 15:15:07
问题 Firstly, bear with me here. I have a custom model binder which is successfully mapping form data to a custom object. Within this model binder it also maps form items to different custom object. What I feel I should be able to do is create a separate model binder to take care of this second mapping. This is a simplified version. Custom objects: public class Category { public int CategoryId { get; set; } public string Name { get; set; } public string Status { get; set; } public string

ASP.NET MVC: avoid tight coupling when binding form POST to parameter

由 大城市里の小女人 提交于 2019-12-06 09:39:36
问题 Let's say I have an interface like: interface IThing { int Id { get; set; } string Title { get; set; } } And in ASP.NET MVC I have a form that posts to a controller action like this: [AcceptVerbs(HttpVerbs.Post)] public ActionResult NewThing([Bind(Exclude = "Id")] SimpleThing thing) { // code to validate and persist the thing can go here } Where SimpleThing is a concrete class that just barely implements IThing . However, I would like all my methods to deal with the interface. I have a data

Is there a way to have the DefaultModelBinder ignore empty items when binding to a List<Enum>

由 烈酒焚心 提交于 2019-12-06 07:39:14
问题 I have a scenario where I'd like to change the behavior of the DefaultModelBinder in how it binds to a List of enums. I have an enum... public enum MyEnum { FirstVal, SecondVal, ThirdVal } and a class for a model... public class MyModel { public List<MyEnum> MyEnums { get; set; } } and the POST body is... MyEnums=&MyEnums=ThirdVal Currently, after model binding, the MyEnums property will contain... [0] = FirstVal [1] = ThirdVal Is there was a way to tell the model binder to ignore the empty

Is it okay to hit the database from a custom model binder?

由 孤人 提交于 2019-12-06 06:34:59
问题 Say I have an object that gets some data from HttpPost and some from the database. I think I want to allow the ModelBinder to go to the database/repository for the that data missing from the post. In practice, is this a good or bad idea? 回答1: I've decided to edit my original answer given my thinking on these types of things has evolved since early 2010. In my original answer, I basically expressed that, while my instincts told me you shouldn't do this, I was uncomfortable saying we shouldn't
