ASP.NET MVC模型绑定到列表 [英] ASP.NET MVC Model Binding into a List

问题描述

在我的ASP.NET MVC网站中，功能的一部分允许用户输入某个场地打开的时间。

我决定存储这些时间在我的数据库中的VenueHours表中，与Venues表中有一个FK到PK的关系，以及DayOfWeek，OpeningTime和ClosingTime参数。

我的观点，我想允许用户只输入他们知道的时间;换句话说，有些日子可能不会填写在场地。我正在考虑创建用户可以检查的复选框，以启用该复选框所属的DayOfWeek的OpeningTime和ClosingTime字段。

---

我的问题涉及如何将此信息传递给我的HttpPost控制器操作。

由于我知道最大天数可以通过（7），我当然可以在我的Action中写入7个可空的VenueHour参数，但我确定有一个更好的方法。

我可以不知何故将查看信息绑定到传递给我的Action 的列表中？如果我遇到一个不能限制用户填写多少信息的情况，这也将帮助我。

解决方案

Scott Hanselman发布了关于默认模型binder如何处理集合，数组的非常好的文章和字典。如果您不想编写自定义模型绑定器，那么很好，尽管编写自定义模型绑定不是一件大事。

In my ASP.NET MVC site, part of a feature allows the user to enter the hours when a certain venue is open.

I've decided to store these hours in a VenueHours table in my database, with a FK-to-PK relationship to a Venues table, as well as DayOfWeek, OpeningTime, and ClosingTime parameters.

In my View, I want to allow the user to only input the times they know about; in other words, some days may not be filled in for a Venue. I'm thinking of creating checkboxes that the user can check to enable the OpeningTime and ClosingTime fields for the DayOfWeek that the checkbox belongs to.

---

My question relates to how to pass this information to my HttpPost Controller Action.

As I know the maximum amount of Days that can be passed in (7), I could of course just write 7 nullable VenueHour parameters into my Action, but I'm sure there's a better way.

Can I somehow bind the View information into a List that is passed to my Action? This will also help me if I run into a scenario where there is no limit to how much information the user can fill in.

解决方案

Scott Hanselman posted a very good article about how the default model binder deals with collections, arrays and dictionaries. It's great if you don't want to write a custom model binder, although writing a custom model binder isn't that big a deal.
