Razor if statement counter issue v7.4

Hi,

I'm new to Razor and trying to carry out what should be a simple task but my code is not working. I am displaying the results of a query (in a partial) and within that query I have set up a counter so that I can wrap different HTML around the items, depending which number they are.

So, it looks like this:

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage


@{ var selection = CurrentPage.Site().FirstChild("articleRepo").Children("article").Where("Visible").OrderBy("CreateDate desc").Take(10); }

@if (selection.Any())
{
    var n = 0;
    <div>

        @foreach (var item in selection)
        {
            var imagePath = @item.image640;
            n++;

            if(n==1){
            do one things
            } else {
            do another
            }

            <div class="col-sm-6 hp-two-story">
                @n<img class="lazy" data-original="@("http://www.website.org" + imagePath)" />
                <p><a href="@item.Url">@item.Name</a></p>
            </div>
        }
    </div>
}

The content shows just fine until I put the..

      if(n==1){
        do one things
        } else {
        do another
       }

Then it throws errors. I msut have tried 100 variations of this, but I'm close to going insane. I get the same errors whether using Back OFfice or VS.

Howver, if I do this:

@foreach (var item in selection)
{
   var imagePath = @item.image640;
    n++;


    <div class="col-sm-6 hp-two-story">
        @if (n == 1) { 
            <p>Do one thing</p>
        }
        else
        {
            <p>Do another</p>
        }
        @n<img class="lazy" data-original="@("http://website.org" + imagePath)" />
        <p><a href="@item.Url">@item.Name</a></p>
    </div>
}

I don;t get any errors.

The Razor is fussy about being before/after HTML tags?

I don't get it.

Yes, it can be a bit confusing when your new to Razor with before/after HTML tags. Generally if you are inside a HTML tag, it sholud be a @ before the statement, and if its inside another statment (if statement inside an foreach) then it should not have a starting @.

are you asking about outputting formatted text inside the if...else statement?

You will probably either want to use the <text>block</text> or @Html.Raw("output string") depending on your needs.

OK I got it to work using this code:

@{ var selection = CurrentPage.Site().FirstChild("articleRepo").Children("article").Where("Visible").OrderBy("CreateDate desc").Take(12); }

@if (selection.Any())
{
    var n = 0;
    <text>

        @foreach (var item in selection)
        {
            n++;
            var cssClassNames = "";
            var imagePath = @item.imagePath640;

           <text>  
           @if (n == 1) {
               cssClassNames = "col-sm-12 hp-one-story";
           } else if (n > 1 && n < 4)  {
               cssClassNames = "col-sm-6 hp-two-story";
           }
           else 
           {
               cssClassNames = "col-sm-4 hp-three-story";
           }         
           </text>
            <div class="@cssClassNames">
                <a href="@item.Url">
                    <img class="lazy" data-original="@("http://website.org" + imagePath)" />
                </a>
                <p><a href="@item.Url">@item.Name</a></p>
            </div>
        }
    </text>
}

So is this a standard/good practice way to do it or have I just got lucky?
