C＃泛型，我做错了什么？

Question

I'm some what new to Generics and I can't figure out why the following doesn't work.

I have an extension to IEnumerable<T> , called Grid and it looks like so

  public static class IEnumberableGridExtension
  {
        public static HelperResult Grid<T>(this IEnumerable<T> gridItems, Action<GridView<T>> thegrid) 
        {
            ........
        }

   }

Say, I have a variable in my razor Model called "Products" and it is the type List<Product> , so I tried to do

@Model.Products.Grid<Product>(grid=>{
...
});

It states "Cannot convert method group 'Grid" to non-delegate type 'object'. Did you intend to invoke the method?", with "@Model.tasks.Grid" red underlined.

The funny thing is, visual studio compiles, everything is fine. Of course, if i simply do

@Model.Products.Grid(grid=>{
...
});

It's all fine.

The Razor parser is interpreting < and > as normal HTML tags. You can avoid the problem wrapping the call in parenthesis:

@(Model.Products.Grid<Product>(grid=>{
...
}))
