What you can do, is to create a new class and add some properties that you need on JSON data. I guess you do not need all Media properties on Json data. and use the Class instead of Entire Media object.

Here is an example

 public  class MediaPickerProperties
    {

        public  string MediaUrl { get; set; }
        public  int MediaId { get; set; }
    }


   var mediaThingy = Umbraco.TypedMedia(1108);

    var mediaPickerProperties = new MediaPickerProperties
    {
        MediaId = mediaThingy.Id,
        MediaUrl = mediaThingy.Url
    };


    var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

    var mediaJSON = serializer.Serialize(mediaPickerProperties);

    var jsonToMediaPicker = serializer.Deserialize<MediaPickerProperties>(mediaJSON);

    @jsonToMediaPicker.MediaId

Thanks Jivan

I tried implementing your example and I see you did answer it though quite literally. I need the entire contents of the mediaPicker. So the mediaPicker plus its children.

So the mediaPicker is a folder and that folder has contents. I need to get to the contents which are images with basic info; name, url, id, etc.

I'm going to edit my question above.

I can only access the top level properties of the mediapicker object. How can I parse deeper into the object using dot notation?

JavaScript makes it so much simpler where I could have a parent object and parse into it quickly but not in .net.

   someObj.array[0].name = "muffin";
   someObj.array[0].url = "http://www...";

This edited screenshot from above, I'm trying to get down to the array of items contained in the mediapicker but I cannot reference its parent "Results View".

If I can access that deep, I could loop through its contents and create a simple C# object to then serialize to JSON.

Can some one show me how I can parse through to the mediapickers contents(the image files and their properties) so I can convert it?

In the screenshot below. I can't just get to any of the properties. For example...

m1.base. Results View [0].Id

Here is the screenshot of the data I'm ultimately trying to get to and serialize to JSON in the mediapicker. Its in a "non-public member" which I assume is private. I don't know how to get past this issue.

'Umbraco.Web.Models.DynamicPublishedContentList.Items' is inaccessible due to its protection level

How can I make this data accessible so I can simply write this to get the first item of the array:

var item1 = selection.Items[0];

I keep running into this issue:

"Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate"

I did change the name of the helper class from MediaPickerProperties to MediaPickerModel but its still the same thing.

public class MediaPickerModel
{
    public int MediaId { get; set; }
    public string MediaName { get; set; }
    public string MediaUrl { get; set; }
    public List<MediaPickerModel> ChildList { get; set; } 
}

I know that this block of code is the issue and it circles around the value of x. The compiler doesn't like x since its not defined prior to runtime because its dynamic responding with the nebulous error message I called out above. I need to somehow re-write this so x is defined before runtime.

            ChildList = mediaThingy.Children.Select(x =>
                 new MediaPickerModel
                 {
                     MediaId = x.Id,
                     MediaUrl = x.DocumentTypeAlias == "Image" ? x.Url : "",
                     Name = x.Name
                 }).ToList()

  @if(CurrentPage.HasValue("mediaPhotos")){      


        var media = Umbraco.Media(CurrentPage.mediaPhotos);
        var mediaThingy = Umbraco.TypedMedia(media.Id);

        var mediaPickerProperties = new MediaPickerModel
        {
            MediaId = mediaThingy.Id,
            MediaName = mediaThingy.Name,
            ChildList = mediaThingy.Children.Select(x =>
                 new MediaPickerModel
                 {
                     MediaId = x.Id,
                     MediaUrl = x.DocumentTypeAlias == "Image" ? x.Url : "",
                     Name = x.Name
                 }).ToList()
        };

        var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
        var mediaJSON = serializer.Serialize(mediaPickerProperties);
}

OMG, I'm filly getting some where.

It took me the longest time just to realize how to debug this properly.

First the preview loads the previewed page into a iframe. That took me a bit to realize since I couldn't get the JSON value at first. The next issue I'm running into is this error.

base {System.SystemException} = {"Cannot resolve a Url for a media item when there is no 'umbracoFile' property defined."}

Since this is a custom media type, I don't know what could be missing.

I actually don't see any of the fields created with this media type for example I have a link(content picker), headline (text string), and text (textbox multiple). I cannot see any of them in the children list object of the mediapicker.

For the Url property, I figured it would be as simple as comparing my custom type to the image type and changing the properties to match. I changed the "upload" property alias in my custom type to umbracoFile to match the Image media type I see this error.

Url = The function evaluation requires all threads to run.

The only saving grace here is that I do see the Url property though I don't see it defined. Without changing the Upload property in the custom type to match the Image type, it doesn't even show up in the debugger.

is working on a reply...
