Sitecore GlassMapper and Json.NET

Question

I need to pass parameters in Json format from Sitecore item. I am getting Sitecore item using GlassMapper.

public interface ISomeType
{
  //some fields
}
public interface ISomeFolder
{
    IEnumerable<ISomeType> SubItems { get; set; }
}

...

var folder = _sitecoreContext.GetItem<ISomeFolder>(dataSourceId)
var list = folder.SubItems;
var json = JsonConvert.SerializeObject(list); // <= Here I get "Exception of type 'System.StackOverflowException' was thrown."

List type is Glass.Mapper.Sc.LazyItemEnumerable<ISomeType>. It contains Castle.Proxies.ISomeTypeProxy items, I can access to them. I can access to all their fields described in the interface. But I am getting System.StackOverflowException exception when trying to serialize it.

Is it possible to serialize GlassMapper objects to Json using Newtonsoft Json.NET?

If yes then what I am doing wrong? If no, what is the best way to convert GlassMapper object to Json?

Answer 1

The easiest way to solve this would be to use either a custom class or a dynamic one when you serialize:

var folder = _sitecoreContext.GetItem<ISomeFolder>(dataSourceId)
var list = folder.SubItems;
var json = JsonConvert.SerializeObject(list.Select(subitem => new 
                                                   { 
                                                       subitem.Field1,
                                                       subitem.Field2,
                                                       CustomFieldName = subitem.Field3
                                                   }));
