Question

Is possible to Deserialize just a fragment of JSON using JavaScriptSerializer? I don’t need all data from JSON, just a section.

The JSON data look like this:

// **** snip ****
{
    "response":  {
        some data
    }
},
"forecast":  {
    "txt_forecast":  {
    "date": "7:00 AM PST",
    "forecastday":  [ // <-- section needed
        {
            some data....
        },
        .........
        {
            some data....
        }
    ]
},
"simpleforecast":  {
    "forecastday":  [
        more data
    ]
}
// **** snip ****

This is part I need to parse:

"forecastday":  [ // <-- section needed
    {
        some data....
    },
    .........
    {
        some data....
    }
]

I tried with forecast object ( fragment of whole data ), but it returns null.

var jsonData = new WebClient().DownloadString(url);
JavaScriptSerializer ser = new JavaScriptSerializer();
forecast_class forecast = ser.Deserialize<forecast_class>(jsonData);

Will something like this work for you

var dictObj = new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(jsonData);
var jsonNew = new JavaScriptSerializer().Serialize(dictObj["forcast"]);
