how to read json file in C#


JObject o1 = JObject.Parse(File.ReadAllText(@"c:videogames.json"));

// read JSON directly from a file
using (StreamReader file = File.OpenText(@"c:videogames.json"))
using (JsonTextReader reader = new JsonTextReader(file))
{
JObject o2 = (JObject)JToken.ReadFrom(reader);
}

//For any of the JSON parse, use the website
//http://json2csharp.com/
//(easiest way) to convert your JSON into
//C# class to deserialize your JSON into C# object.

public class FormatClass
{
public string JsonName { get; set; }
public string JsonPass { get; set; }
}
//Then use the JavaScriptSerializer (from System.Web.Script.Serialization),
// in case you don't want any third party DLL like newtonsoft.
public void Read()
{
using (StreamReader Filejosn = new StreamReader("Path.json"))
{
JavaScriptSerializer jss = new JavaScriptSerializer();
var Items = jss.Deserialize<FormatClass>(Filejosn.ReadToEnd());
// Add Code here :)
}
}
