I have Blog Repository and it contains blog posts list. I am accessing all Blog Posts by using this code

var contentType = ApplicationContext.Services.ContentTypeService.GetContentType("BlogPost");

var blogPostList = ApplicationContext.Services.ContentService.GetContentOfContentType(contentType.Id);

Now I am accessing custom data type properties by using

foreach (var blog in blogPostList)
    {

        foreach ( var property in blog.Properties)
        {

        }

    }

Now I can access properties and get its value but for few properties I get json String and that is no use for me as I would need to create models to properly parse json string into proper json.

Is there any way to use GetPropertyValue in this situation or some other way to get properly formatted Json.
