Serializing Dictionary< String, Dictionary< String, String > > in any form (Json, xml etc.)

Question

Serializing Dictionary< String, Dictionary< String, String > > to the point where it can be stored, and later de serialized. I've done quite a bit of googling and can't find a class, or function that is compatible with .NET 4.5 Completely.

The out-of-the-box JavaScriptSerializer should be able to cope with your dictionary. It should give quite compact output, too.

var source = new Dictionary<string, Dictionary<string, string>>
{
    { "one", new Dictionary<string, string> { { "a", "1a"}, { "b", "1b" } } },
    { "two", new Dictionary<string, string> { { "a", "2a"}, { "b", "2b" } } }
};

var serializer = new JavaScriptSerializer();

// This gives {"one":{"a":"1a","b":"1b"},"two":{"a":"2a","b":"2b"}}
string serialized = serializer.Serialize(source);

// This gives a clone of the original dictionary.
var deserialized = serializer.Deserialize
    <Dictionary<string, Dictionary<string, string>>>(serialized);

But JavascriptSerializer doesn't exist in Metro for some reason :\ – Manak Kapoor Oct 31 '12 at 08:42
You can't add a reference to `System.Web.Extensions`? In that case, according to [this](http://stackoverflow.com/questions/9573119/how-to-parse-json-without-json-net-library), you could try the [`System.Json`](http://msdn.microsoft.com/en-us/library/system.json.aspx) namespace, but I'm afraid I'm unfamiliar with it and don't have access to 4.5 so I can't offer any further help. – Rawling Oct 31 '12 at 08:47

Well i found the solution is to use JSON.NET

public String Serialize(Dictionary<int, Dictionary<String, String>> all)
        {

            String abc = JsonConvert.SerializeObject(all, Formatting.None, new JsonSerializerSettings
                        {
                            TypeNameHandling = TypeNameHandling.Objects,
                            TypeNameAssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Simple
                        });
            return abc;
        }

         public Dictionary<int, Dictionary<String, String>> DeSerialize(String text)
         {

             Dictionary<int, Dictionary<String, String>> abc;
             abc = JsonConvert.DeserializeObject<Dictionary<int, Dictionary<String, String>>>(text, new JsonSerializerSettings
             {
                 TypeNameHandling = TypeNameHandling.Objects,
                 TypeNameAssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Simple,
             });
             return abc;
         }
