Getting tags field only gives me a System.string[] string
I'm trying to render a list of article tags but all I get is a single string of System.string[].
```
@if (Model.Content.HasValue("tags"))
{
    var tags = Umbraco.Field("tags").ToHtmlString().Split(',');

    foreach (var tag in tags)
    {
        <div class="badge badge-info">@tag</div>
    }
}
```
I know the article has tags added to it. So what am I doing wrong?

Hi Johan,

you mean something like this:

@if (Model.Content.HasValue("tags"))
{
    string[] tagsList = Model.Content.Tags.ToString().Split(',');

    if (tagsList.Count() > 0)
    {
        @foreach (var tag in tagsList)
        {
            <div class="badge badge-info">@tag</div>
        }
    }
}

Hope this helps!

Hey Michaël!

I tried your version too with the same result.

I get <div class="badge badge-info">System.string[]</div> rendered out. =/

Johan,

which version are you using?

There has been a change in the property value convertors, can you try to disable them and try again:

In umbracoSettings.config set EnablePropertyValueConverters to false.

Hope this helps!

It's 7.8.1.

Setting that to false breaks the rendering of the pages.

It's 7.8.1.

Setting that to false breaks the rendering of all pages.

Hi Johan,

It's generally best to use the Property Value converters, it makes things alot easier.

You should be able to simply do this:
```
@if (Model.Content.HasValue("tags"))
{

    if (Model.Content.Tags != null)
    {
        foreach (var tag in Model.Content.Tags)
        {
            <div class="badge badge-info">@tag</div>
        }
    }
}
```
This is because the conversion from a comma separated list is happening in the Property Conversion so you don't need to do anything with it. The property just gives you back the array of strings to iterate around :-)

Thanks,

Nik

I'm trying to do something similar but with no luck. This is my code:

 @{
            var selection = Model.Content.Site().FirstChild("container").Children().Where(x => x.IsVisible());
                }
                <div id="portfolio" class="portfolio grid-container portfolio-3 portfolio-masonry clearfix">                 
                    @foreach(var item in selection){

                        string imageUrl = item.GetPropertyValue<IPublishedContent>("rollupImage").Url;
                        var tags = item.GetPropertyValue<string>("tags");
                        foreach (var tag in tags)
                        {
                            <span>@tag</span>
                        }

                        <article class="portfolio-item pf-media pf-netherlands">
                            <div class="portfolio-image">
                                <a href="portfolio-single.html">
                                    <img src="@imageUrl" />
                                </a>
                                <div class="portfolio-overlay">
                                    <a href="@imageUrl" class="left-icon" data-lightbox="image"><i class="icon-line-plus"></i></a>
                                    <a href="@item.Url" class="right-icon"><i class="icon-line-ellipsis"></i></a>
                                </div>
                            </div>
                            <div class="portfolio-desc">
                                <h3><a href="@item.Url">@item.Name</a></h3>

                            </div>
                        </article>
                    }
                </div>

But all I get is System.string[]

What am I doing wrong here?

Hi Joop,

The issue you have is most likely this:
```
var tags = item.GetPropertyValue<string>("tags");
```
You are explicitly telling the property converters to turn tags into a single string, when you actually want it to be an enumerable object.

Try replacing it with this line:
```
var tags = item.GetPropertyValue<string[]>("tags");
```
and see how you get on.

Thanks,

Nik

are you just calling .ToString() on your value?

a System.String[] is an array, and you need to iterate it to render each value
```
@foreach(var tag in [...]) {
    <a href="news/?tag=@tag">@tag</a>
}
```
