Using a Ternary Conditional with in Asp.Net MVC Razor

Question

I am trying to get the following ternary conditional to work in Asp.Net MVC 3 Razor:

<a href="@Url.Action("TestBrowse", new { page = @(Model.IsLastPage ? Model.PageNumber : Model.PageNumber + 1) })">Next</a>

All of the examples I am finding of using a ternary conditional in Razor have return values which are strings. But here I would like to use an expression (Model.PageNumber + 1) and return a number. Is this possible?

Drop the @ sign before the value:

<a href="@Url.Action("TestBrowse", new { page = Model.IsLastPage ? Model.PageNumber : (Model.PageNumber + 1) })">Next</a>

Let me just add that in general, Razor doesn't need/want the @ prefix unless it's absolutely necessary, for example:

<div>
@foreach(var value in Model.Values)
{
if(value.Flag)
{
<div>@value.Text</div>
}
}
<div>

Notice that you don't need a second @ sign until you're actually inside the tag, where Razor wouldn't know whether you wanted to display the text "value.Text" or execute it as code. The if statement is assumed to be code. To escape this and write the line "if(value.Flag)" as text you'd need to explicitly say so with the @: prefix.
