How can I convert HtmlText to a normal string in c#

Question

I have the following model:

namespace power.Storage.Models
{
    public class Answer
    { 
        public HtmlText[] Explanation { get; set; }
        public string[] ImageFile { get; set; }
    }

    public class HtmlText { 
        [AllowHtml]
        public string TextWithHtml { get; set; } 
    }
}

Now I want to be able to take the data from answer and do the following:

String[] _code_explanation = null;
_code_explanation = 
 (string) JSON.FromJSONString<Answer>(_code.AnswersJSON).Explanation;

But it's not working. It says "can't convert HtmlText to string

Is there something I'm missing? I thought all I would need to do was to add (string) before the JSON...

Here's the code for JSON

    public static T FromJSONString<T>(this string obj)
    {
        using (var stream = new MemoryStream(Encoding.UTF8.GetBytes(obj)))
        {
            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
            T ret = (T)ser.ReadObject(stream);
            return ret;
        }
    }

The following half works:

HtmlText[] _code_explanation = null;
    _code_explanation = 
     (string) JSON.FromJSONString<Answer>(_code.AnswersJSON).Explanation;

It gives me an array of HtmlText but then I am not sure how to convert this into a simple array of strings.

I do not know the answer to this particular question, but usually you do not cast to string, instead you call the .ToString() method JSON.FromJSONString<Answer>(_code.AnswersJSON).Explanation.ToString(); might work? — Wouter Simons

The .ToString() seems like it might work but the problem is that The ouput is an array. What I need is an ToStringArray :-( — SeanMcD

HTMLText does not have a cast operator to String, explicit or implicit.

You can decode HtmlText with with the HttpUtility.HtmlDecode method. It cannot be directly cast to a string.

But where can I put this? First I have to put the data into an array of something and what I am getting back is an array of HtmlText

I think you want to do something like this assuming teh Explanation is of type HtmlText

String[] _code_explanation = null;
_code_explanation = 
   JSON.FromJSONString<Answer (_code.AnswersJSON).Explanation.TextWithHtml;
