Deserialize a json array in asp.net

Question

i have the following json string from an http post:

Dim json As String = "{" + """contacts"":" + "[{" + """name"":""jocelyne" + """," + """mo"":""jocelyne" + """}" + ",{" + """name"":""eliane" + """," + """mo"":""12345678" + """}" + "]}"

how can i deserializa this json array? i tried using dictionary but it did not work note that the length of the json array may be very big

 Dim jss As New System.Web.Script.Serialization.JavaScriptSerializer()
 Dim dict As Dictionary(Of String, String) = jss.Deserialize(Of Dictionary(Of String, String))(json)
 For Each item As KeyValuePair(Of String, String) In dict
        Response.Write(item.Key & " - " & item.Value & "<br>")
    Next

Maybe better idea to deserialize it to custom object? http://stackoverflow.com/questions/9586585/convert-json-to-a-c-sharp-array — Mike, Oct 17 '13 at 11:40

Try using JSON.Net

  Dictionary<string,string> deserializedProduct =
    JsonConvert.DeserializeObject<Dictionary<string,string>>(json);

Try this, this is C# code

dynamic obj = JsonConvert.DeserializeObject(json);
var contacts = obj["contacts"];

try this

   System.Web.Script.Serialization.JavaScriptSerializer ss1 = new System.Web.Script.Serialization.JavaScriptSerializer();
Dictionary<string, string> dicobj = new Dictionary<string, string>();
        dicobj = ss1.DeserializeObject(JsonString) as Dictionary<string, string>;
