Question

I am trying to serialize a Dictionary to JSON, and get the following exception:

new JavaScriptSerializer().Serialize(mydict)`

Ty

Answer 1

The blog http://dukelupus.wordpress.com/2011/05/04/asp-net-mvc-json-and-a-generic-dictionary/ describes an extension method Dictionary ToJsonDictionary(this Dictionary input)

Answer 2

use NewtonSoft.Json instead of JavaScriptSerializer to overcome this problem:

Ex:

JsonConvert.SerializeObject(mydict);

Answer 3

var dict = mapping.ToDictionary(item => item.Key.ToString(), item => item.Value.ToString());`

that will convert any Dictionary<K,V> to Dictionary<string,string> and serialization then works.
