装饰在ViewModel属性上使用不同的名称进行绑定(Decoration on ViewModel property to use a different name for binding)

装饰在ViewModel属性上使用不同的名称进行绑定(Decoration on ViewModel property to use a different name for binding)

在MVC3上，有没有办法装饰ViewModel属性以使DefaultModelBinder在请求中使用不同的名称？

例如，假设您有以下视图模型：

public class SomeModel { public string Direction {get;set;} }

但是来自外部源（例如某些第三方组件）的Dir参数。

我知道自定义模型绑定器可以处理它，但我认为必须有一种方法来装饰属性，类似于动作参数可以使用Bind(Prefix="...")的方式来定义该映射。

On MVC3, is there a way to decorate a ViewModel property in order to get the DefaultModelBinder to use a different name for it in the request?

For example, suppose you have the following view model:

public class SomeModel { public string Direction {get;set;} }

But the parameter coming in is Dir from an external source (such as some third-party component, for example).

I know a custom model binder could handle that, but I assume there must be a way to decorate the property, similar to the way action parameters can use Bind(Prefix="...") in order to define that mapping.

最满意答案

您可以随时创建另一个属性：

public class SomeModel { public string Direction {get;set;} public string Dir { get { return this.Direction; } set { this.Direction = value; } } }

我还要提到视图中使用的ViewModel（cshtml / vbhtml）不必与Post方法中使用的ViewModel相同。

OK, so after more research looking at similar questions and seeing the feedback here as well, it seems that the answer to my question is basically "NO".

There is no out-of-the-box way, so either custom binders must be used or or the properties should be renamed.
