Question

I’m trying to serialize a Hashtable with ServiceStack JsonSerializer. Unlike Json.Net and built-in JavaScriptSerializer, however, it returns type names of DictionaryEntry instead of values.

This code:

Hashtable h = new Hashtable(){ { "A", 1 }, { "B", 2 } };

Console.WriteLine(JsonConvert.SerializeObject(h));
Console.WriteLine(new JavaScriptSerializer().Serialize(h));
Console.WriteLine(ServiceStack.Text.JsonSerializer.SerializeToString(h, typeof(Hashtable)));

Returns this:

{"A":1,"B":2}
{"A":1,"B":2}
["System.Collections.DictionaryEntry","System.Collections.DictionaryEntry"]

Am I doing something wrong?

The latest version of ServiceStack.Text (v3.9.11+) on NuGet now includes support for Hashtable.
