Error in RenderPartial in loop asp.net mvc

Question

I am trying to render multiple Views using a loop like this

@model IEnumerable<RamtaJogi.Web.Razor.Controllers.IMenuRenderer>

@foreach (var item in @Model)
{
    {@Html.RenderPartial(@item.ViewName, @item.ViewData);}
     <br />
}

here is my IRenderer

public interface IMenuRenderer     
{
    string ViewName { get; }
    object ViewData { get; }
}

But it throws an error CS1502: The best overloaded method match for 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' has some invalid arguments

I pass a collection of objects of type IMenuRenderer to my view.

Any idea what is wrong with my codes. Can someone help here.

Can you post your implementation of IRenderer/IMenuRenderer ? — Bala R, May 01 '11 at 05:38

You have too many @ characters.

You should only use @s to enter the foreach.
Since RenderPartial returns void, you cannot print its result with an @.
Parameters also never get @s.

Change your code to

@model IEnumerable<RamtaJogi.Web.Razor.Controllers.IMenuRenderer>

@foreach (var item in Model)
{
    @Html.Partial(item.ViewName, item.ViewData)
     <br />
}
