Multiple Else if inside if statement. Umbraco Code interpretation

Razor

Umbraco 4

Hey guys, How would one write this correctly?

   @if (x = y) {
       // Do something
   } else if (x = 1) {
      // Do something else
   } else if (x = 2) {
      // Do something wild
   } else {
     // Do something wildly
   }

The last else if and the else will not be interpreted as code and I cant figure where to place the extra @ tag. Can anyone help me?

Full code is:

@inherits Umbraco.Web.Macros.PartialViewMacroPage

    <h2>ARTIKLER</h2>
@{

    var years = Umbraco.Content(3772).Children;
    for (int i = 0; i < years.Count(); i++) {

        var page = years[i];

        if (i < 3) {
            <a class="btn btn-primary" href="@page.Url">@page.Name</a>
        } else if (i == 3) {
            <label id="lblSelect">
                <select id="selectPointOfInterest" title="Vælg årstal" onchange="location = this.value;">
                    <option value="@page.Url">@page.Name</option>
        } else if (i < years.Count() && i > 3) {
                    <option value="@page.Url">@page.Name</option>
        } else if (i == years.Count()-1) {
                    <option value="@page.Url">@page.Name</option>
                </select>
            </label>
        }
    }
}

Hi Nicolai,

When you have multiple else if statements it's sometimes better to use a switch https://msdn.microsoft.com/en-us/library/06tc147t.aspx

You code may look something like the following:
```
@{
    switch(x)
    {
        case 1:
            // Do something
            break;
        case 2:
            // Do something
            break;
        default:
            // Do something
            break;
    }
}
```
The default statement in the switch acts the same as your intended behaviour for else. Try giving it a shot as it's probably better practice than multiple else if's.

Hi Gary,

Thanks for trying to help! Im afraid I cant use switch case statements in this particularly situation because I need the logical operations.

I have added the full code example to my main post.

Regards, Nicolai

The problem with the example is opening some html tags withouth closing them in the same branch of the IF.

Try generating a string of your html and then printing it out

I found a solution to this problem if anyone is interested :-)

<h2>PAGE</h2>
    @{

        var years = Umbraco.Content(3772).Children;
        for (int i = 0; i < years.Count(); i++) {

            var page = years[i];

            if (i < 3) {
                <a class="btn btn-primary" href="@page.Url">@page.Name</a>
            } else if (i == 3) {
                @:<label id="lblSelect">
                    @:<select id="selectPointOfInterest" title="Vælg årstal" onchange="location = this.value;">
                        <option value="@page.Url">@page.Name</option>
            } else if (i < years.Count() && i > 3) {
                        <option value="@page.Url">@page.Name</option>
            } else if (i == years.Count()-1) {
                        <option value="@page.Url">@page.Name</option>
                    @:</select>
                @:</label>
            }
        }
    }
