asp.net razor if syntax

Question

I'm a beginner with ASP.NET MVC and I'm trying to set the src of an image with razor in a asp.net MVC website using an If statement.

this code works :

 <img src="@Url.Action("GetPersonPhoto", "Home", new RouteValueDictionary( new { cardid = "696969" }) )" />

I want to add :

@if(Model.HavePhoto)

And set the src to :

"~/Content/images/header-logo.png"

if HavePhoto is false...

How can I do it ?

RT(F)M. Ok, to be serious...google any example. Image source itself shouldn't be IMO inside your cshtml page but decided in controller and stored in model src="@Model.PhotoUrl" — Adriano Repetti

I would have the GetPersonPhoto action decide which image to use and handle cases where Model.HavePhoto are false, providing the url of a default image, as oppose to handle this in the view layer — MilkyWayJoe

See stackoverflow.com/questions/9399531/… and stackoverflow.com/questions/8061647/… for couple options, you could also just have two different img tags, one in the if and one in an else for each case — AaronLS

    var source= "~/Content/images/header-logo.png";
    @if(Model.HavePhoto)
    {
       source= Url.Action("GetPersonPhoto", "Home", 
                   new RouteValueDictionary( new { cardid = "696969" }))
    }

    <img src="@source" />

Depending on the context you probably need to wrap the variable declaration @{ var source= "~/Content/images/header-logo.png"; }

Thanks. I have a null reference exception with "@if(Model.HavePhoto)" but otherwise your solution seems to work.
