How can I deserialize JSON to a simple Dictionary in ASP.NET?

Question

I have a simple key/value list in JSON being sent back to ASP.NET via POST. Example:

{ \"key1\": \"value1\", \"key2\": \"value2\"}

Answer 1

I would suggest using System.Runtime.Serialization.Json that is part of .NET 4.5.

[DataContract]
public class Foo
{
   [DataMember(Name = "data")]
   public Dictionary Data { get; set; }
}

Then use it like this:

var serializer = new DataContractJsonSerializer(typeof(List));
var jsonParams = @"{""data"": [{""Key"":""foo"",""Value"":""bar""}] }";
var stream = new MemoryStream(Encoding.UTF8.GetBytes(jsonParams));

var obj = serializer.ReadObject(stream);
Console.WriteLine(obj);
