asp.net mvc4 razor pass view model to helper

问题

I want to pass view model to my html helper/ I have tried

 public static string GenerateFullTable(this HtmlHelper helper, IEnumerable<CarsViewModel> model)
        {

But I dont know which model would be.

Does it possible to make universal helper which gets would get different view models?

回答1:

Yes, it's called Generics.

Edit:

Here's one example...

public static string GenerateFullTable<T>(this HtmlHelper helper, IEnumerable<T> model)
{
    ...
}

You can further constrain T to be of a specific type or inheriting certain interface, maybe something like this:

public static string GenerateFullTable<T>(this HtmlHelper helper, IEnumerable<T> model) where T : MyModelsInterface
{

}

But that depends on your needs. Hope this helps ;)
