c# - ASP.Net MVC: Calling a method from a view

Question

In my MVC app the controller gets the data (model) from an external API (so there is no model class being used) and passes that to the view. The data (model) has a container in which there are several objects with several fields (string values). One view iterates over each object and calls another view to draw each of them. This view iterates over the fields (string values) and draws them.

Here's where it gets tricky for me. Sometimes I want to do some special formatting on the fields (string values). I could write 20 lines of code for the formatting but then I would have to do that for each and every field and that would just be silly and oh so ugly. Instead I would like to take the field (string value), pass it to a method and get another string value back. And then do that for every field.

So, here's my question:

How do I call a method from a view?

I realize that I may be asking the wrong question here. The answer is probably that I don't, and that I should use a local model and deserialize the object that I get from the external API to my local model and then, in my local model, do the "special formatting" before I pass it to the view. But I'm hoping there is some way I can call a method from a view instead. Mostly because it seems like a lot of overhead to convert the custom object I get from the API, which in turns contains a lot of other custom objects, into local custom objects that I build. And also, I'm not sure what the best way of doing that would be.

Disclaimer: I'm aware of the similar thread "ASP.NET MVC: calling a controller method from view" (ASP.NET MVC: calling a controller method from view) but I don't see how that answers my question.

Answer 1

This is how you call an instance method on the Controller:

@{
  ((HomeController)this.ViewContext.Controller).Method1();
}

This is how you call a static method in any class

@{
    SomeClass.Method();
}

This will work assuming the method is public and visible to the view.
