Hi Biagio

When you are querying the published cache of Umbraco, it's optimised to contain the most efficient amount of information for building a website.

Consequently, when you are looping through the 'Properties' of an Element Type, like in your example, you will find you are being given reference to IPublishedProperty objects

https://github.com/umbraco/Umbraco-CMS/blob/e17fa957d6c6a0ee38e5c07bcb43c26b1fe4cae2/src/Umbraco.Core/Models/PublishedContent/IPublishedElement.cs#L35

And as you have found, these objects do not include the Name as presented in the backoffice:

https://github.com/umbraco/Umbraco-CMS/blob/e17fa957d6c6a0ee38e5c07bcb43c26b1fe4cae2/src/Umbraco.Core/Models/PublishedContent/IPublishedProperty.cs#L6

Because normally you wouldn't need to render that name anywhere in your site...

... But there is a way to get the full information of an Element Type including the name and that is to use the ContentTypeService - but be aware - these services hit the database and so if used on the front end, need to be cached, otherwise will be super slow!

Anyway, if you inject the ContentTypeService into your code you'd be able to write something like

IContentType contentTypeInfo = contentTypeService.Get(item.Alias);
foreach (var propertyType in contentTypeInfo.PropertyTypes) {
     Debug.WriteLine("-----");
     Debug.WriteLine(propertyType.Name);
     Debug.WriteLine(item.GetValue(propertyType.Alias)));
}

Thanks to reply me. The performance is not a problem. I’ve a lots of fields and I’ve to create a pdf report. Then I don’t want to write in the code the field names. I made a simple test. I pass the field alias ( the field of the elemet type of the block item ) into the content type service but it return a null value. Wht?

Hi Biagio

In the image above 'codicePiano' appears to be a text field...

The ContentTypeService works with Element Types and Document Types

so you'll need the alias for 'Preventivo Row Item' (it's not in the screenshot, but should be on the right hand side of the screen) possibly it is just 'preventivoRowItem'

Then you will be able to do a foreach over it's PropertyTypes

IContentType preventivoRowItem = contentTypeService.Get("preventivoRowItem");
foreach (var propertyType in preventivoRowItem.PropertyTypes) {
     Debug.WriteLine("-----");
     Debug.WriteLine(propertyType.Name);
     Debug.WriteLine(item.GetValue(propertyType.Alias)));
}

fingers crossed!

I attach the document type images because there is something that don't work. I pass the alias of the BlockList item that is "righePreventivo" and I've the info, but the value is the json list.

This works, but I don't like very much...

var pu = _publishedContentQuery.Content(5686);
        IEnumerable<BlockListItem> lista = new List<BlockListItem>();
        lista = (IEnumerable<BlockListItem>)pu.GetProperty("righePreventivo").GetValue();
        var listaaa = lista.Select(x => x.Content);
        foreach (var item in listaaa)
        {
            IContentType contentTypeInfo = _contentTypeService.Get(item.ContentType.Alias);
            foreach (var item2 in item.Properties)
            {
                var valore = contentTypeInfo.PropertyTypes.Select(x => x.Alias == item2.Alias).FirstOrDefault();
                var nome = "";
                foreach (var propertyType in contentTypeInfo.PropertyTypes)
                {
                    if (propertyType.Alias == item2.Alias)
                    {
                        nome = propertyType.Name;
                        break;
                    }
                }
                Debug.WriteLine(nome);
                Debug.WriteLine(item.Value(item2.Alias));
                Debug.WriteLine("-----");
            }
        }

Is't not possible to use contentUdi or contentTypeKey to query the type or data of BlockList?

{"layout":{"Umbraco.BlockList":[{"contentUdi":"umb://element/94548b86e9f945baaeb1bf93b166473f"}]},"contentData":[{"contentTypeKey":"483395c5-44c0-4893-bac0-e69c3cbf9428","udi":"umb://element/94548b86e9f945baaeb1bf93b166473f"

I found another better solution:

if (p.PropertyType.PropertyEditorAlias == "Umbraco.BlockList")
                        {
                            IEnumerable<BlockListItem> lista = new List<BlockListItem>();
                            List<TableRowType> elenco = new List<TableRowType>();

                            BlockValue blockValue =  JsonConvert.DeserializeObject<BlockValue>(_content.GetValue(p.Alias).ToString());

                            if (blockValue is null) continue;

                            foreach (var item in blockValue.ContentData)
                            {   var contentType = _contentTypeService.Get(item.ContentTypeKey);

                                foreach (var itemProperty in item.RawPropertyValues)
                                {
                                    IContentType contentTypeInfo = _contentTypeService.Get(contentType.Alias);

                                    var nome = "";
                                    foreach (var propertyTypeLocal in contentTypeInfo.PropertyTypes)
                                    {
                                        if (propertyTypeLocal.Alias == itemProperty.Key)
                                        {
                                            nome = propertyTypeLocal.Name;
                                            break;
                                        }


                                    }

                                    Debug.WriteLine(nome);
                                    Debug.WriteLine(itemProperty.Value);
                                    Debug.WriteLine("-----");

                                    TableRowType tableRowTypeBlock = new TableRowType();
                                    tableRowTypeBlock.tipoRiga = "rigablock";
                                    tableRowTypeBlock.titolo = nome;
                                    tableRowTypeBlock.tipoContainerDataType = p.PropertyType.PropertyEditorAlias;
                                    tableRowTypeBlock.titolocella = nome;
                                    if (itemProperty.Value is string)
                                        tableRowTypeBlock.valorecella = itemProperty.Value.ToString();

                                    elenco.Add(tableRowTypeBlock);
                                }     
                            }
   }

Hi Biagio

Yes, the ContentTypeService has an overload for the key too... glad you got there!
