asp.net-mvc - 为模型元组创建 MVC 自定义模型绑定(bind)器

Question

需要帮助创建 MVC 自定义模型绑定(bind)器以将多个模型元组发布到 Controller 。从未使用过自定义模型 Binder 。已经看过这个问题的其他答案，但是，在处理模型元组或提供所需的解决方案时似乎并没有接近。任何想法表示赞赏。 - 谢谢

Controller

[HttpPost]
public ActionResult CreateContact(Tuple<Contact, Communications, Addresses> tuple) {
      //…. Do tuple processing to transfer values to add values to App Service here.
}

为什么不尝试将“联系人、通信、地址”模型保留在新模型中并将其绑定(bind)到 View 。

这将使处理变得非常简单。
