How to loop all properties of a document?
Hi,

In a template I want to loop through all nodes of a node/doc type (in order to output that node as json).

How do I loop properties and get
- property name
- datatype
- value
for each property?

Don't know if this will help, but may give you an idea.

I wanted to export all the meta descriptions from all the pages in my site, so this is basically what I did

public ActionResult ExportMetaData()
{
    int count = 0;
    List<string> pages = new List<string>();
    IPublishedContent homePage = Umbraco.Content(Guid.Parse("a53c075a-61a2-456e-a73d-e65e52efea92"));

    CountNodes(homePage.Children,ref pages, ref count);

    JsonResult ret = Json("{\"Synchronised\":[" + string.Join(",", pages.ToArray()) + "]}");

    return ret;
}
private void CountNodes(IEnumerable<IPublishedContent> children, ref List<string> pages, ref int count)
{
    count += children.Count();
    foreach (IPublishedContent item in children)
    {
            var test = (PublishedContentModel)item;

        if(item.Children != null)
        {
            if (test.GetProperty("metaName") != null)
            {
                pages.Add("{\"Id\":\"" + test.Id + "\",\"Name\":\"" + test.Name + "\",\"metaName\":\"" + test.GetProperty("metaName").GetValue().ToString() + "\",\"Description\":\"" + test.GetProperty("metaDescription").GetValue().ToString() +"\"}");
            }

            CountNodes(item.Children, ref pages, ref count);
        }else{
            if (test.GetProperty("metaName") != null)
            {
                pages.Add("{\"Id\":\"" + test.Id + "\",\"Name\":\"" + test.Name + "\",\"metaName\":\"" + test.GetProperty("metaName").GetValue().ToString() + "\",\"Description\":\"" + test.GetProperty("metaDescription").GetValue().ToString() +"\"}");
            }
        }

    }

}

Hi Martin.

If you wish to loop through all properties defined by the document type, including compositions, you can simply:
```
var content = UmbracoContext.Content.GetById(1234);

var properties = content.Properties; 
```
That will give you all properties. A property is of type IPublishedProperty, check out the interface for more info on what it contains: https://github.com/umbraco/Umbraco-CMS/blob/v8/contrib/src/Umbraco.Core/Models/PublishedContent/IPublishedProperty.cs

A good tip for the future: get comfortable in Umbracos source code at least the IPublished* part, that will help you a lot in the future and save you a lot of time, when you need to do something that is a little more advanced. :-)

Hope my answer can help you,

Regards

Thank you, both Huw and Malthe,

I found out (with help from the Facebook-group) that the answer was .Properties as you suggest, Malthe:
```
foreach (var property in Model.Properties)
{
     // Model.Value(property.Alias)
}
```
(my task was making a template to use as altTemplate for every page in order do output json with the data of this page)

I will look more into IPublished and like in the docs also. :)
