Parse Json in Umbraco razor

Question

How can i parse this Json:

[{
"value": "",
"date": {
  "value": "17/04/2015"
},
"hour": {
  "value": "21:00"
},
"venue": {
  "value": "some stadium."
}},  {
"value": "",
"date": {
  "value": "18/04/2015"
},
"hour": {
  "value": "20:30"
},
"venue": {
  "value": "some stadium"
}}]

I tried this code:

var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

foreach (var item in serializer.Serialize(item.dates))
{
   @* item == "34 ''" *@
}

but its return string "34 ''" instead what i want.

can someone help me to understand what i missed? Thanks

Answer 1

You should use the DeserializeObject -Method instead of the Serialize -Method.

It returns an object[] which contains Dictionary<string, object> -Elements (your data)

To get the values from the array, cast the current Item to a Dictonary<string, object> (represents a json object) and access the value with the indexer.

Example:

var v = new JavaScriptSerializer();
        var arr = (object[]) v.DeserializeObject(File.ReadAllText("json.txt"));
for (var i = 0; i < arr.Length; i++)
{
    Console.WriteLine(((Dictionary<string, object>)arr[i])["value"]);
}

Example 2 - Access the value inside of the date object:

var v = new JavaScriptSerializer();
var arr = (object[])v.DeserializeObject(File.ReadAllText("json.txt"));
for (var i = 0; i < arr.Length; i++)
{
    // The current object
    var c = (Dictionary<string, object>) arr[i];
    // Getting the date object
    var date = (Dictionary<string, object>) c["date"];
    // Printing the value inside of the date object
    Console.WriteLine(date["value"]);

    // OUTPUT:
    // 17/04/2015
    // 18/04/2015
}
