Asp.net mvc 3 将路由参数绑定到模型

假设我有一条如下的路线

/{controller}/{action}/{id}

是否可以将id绑定到模型中的属性

public ActionResult Update(Model model)
{
    model.Details.Id <-- Should contain the value from the route...
}

您需要创建自己的自定义模型绑定器

public class SomeModelBinder : IModelBinder {

    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) {
        ValueProviderResult value = bindingContext.ValueProvider.GetValue("id");

        SomeModel model = new SomeModel() { Details = new Details() };
        model.Details.Id = int.Parse(value.AttemptedValue);

        //Or you can load the information from the database based on the Id, whatever you want.

        return model;
    }

}

要注册活页夹，请将其添加到

应用程序\u Start（）

然后，您的控制器看起来与上面的控制器完全相同。这是一个非常简单的例子，但却是最简单的方法。我很乐意提供任何额外的帮助

public class SomeModelBinder : IModelBinder {

    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) {
        ValueProviderResult value = bindingContext.ValueProvider.GetValue("id");

        SomeModel model = new SomeModel() { Details = new Details() };
        model.Details.Id = int.Parse(value.AttemptedValue);

        //Or you can load the information from the database based on the Id, whatever you want.

        return model;
    }

}

ModelBinders.Binders.Add(typeof(SomeModel), new SomeModelBinder());
