Parse JSON string using JSON.Net

First add Newtonsoft.Json to the references of the project. Now suppose we want to parse the following JSON string which contains an array of objects:

"[{"id":"1","userid":"1","name":"node:19:1","datatype":"1","tag":"Node:19","public":"0","size":"488","engine":"5","time":1413697602,"value":"215"},..., {"id":"20", ...}]"

The C# code as as follows:

dynamic data = JsonConvert.DeserializeObject(json_string);
for (int i = 0; i < data.Count; ++i)
{
dynamic item = data[i];

string id = (string)item.id;
string name = (string)item.name;
string tag = (string)item.tag;
int time = (int)item.time;
string value = (string)item.value;

double dbl_value = 0;
double.TryParse(value, out dbl_value);

//do something about the item here
}
