I can't answer it using JavaScriptSerializer but you can do it using json.Net and Linq
var jObj = JObject.Parse(json);
var fields = jObj["fields"]
.Select(x => new Field
{
Id = (int)x["id"],
Type = (string)x["type"],
Value = x["value"] is JValue
? new Dictionary<string,string>(){{"",(string)x["value"]}}
: x["value"].Children()
.Cast<JProperty>()
.ToDictionary(p => p.Name, p => (string)p.Value)
})
.ToList();
private class Field
{
public int Id { get; set; }
public string Type { get; set; }
public Dictionary<string, string> Value { get; set; }
}
PS: I fixed your partial json string as
string json =
@"{""fields"":[
{
""id"":2,
""type"":""nickname"",
""value"":""Hello""
},
{
""id"":3,
""type"":""email"",
""value"":""MyTesting@hotmail.com""
},
{
""id"":1,
""type"":""name"",
""value"":{
""givenName"":""Otopass"",
""middleName"":""Test"",
""familyName"":""Hotmail""
}
}
]}";
