var responseFromServer =
// lines split for readability
"{\"flag\":true,\"message\":\"\",\"result\":{\"ServicePermission\":true,"
+ "\"UserGroupPermission\":true}}";
var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
var responseValue = serializer.DeserializeObject(responseFromServer);
responseFromServer value is get a webservice, and then how to get the JSON string value, such as "flag"，"Servicepermission"？？
affix: i'm sorry, using c# to do this.
Note: The JavaScriptSerializer is actually the slowest JSON Serializer I've ever benchmarked. So much so I've had to remove it from my benchmarks because it was taking too long (>100x slower).
Anyway this easily solved using ServiceStack.Text's JSON Serializer:
var response = JsonSerializer.DeserializeFromString<Dictionary<string,string>>(responseFromServer);
var permissions = JsonSerializer.DeserializeFromString<Dictionary<string,string>>(response["result"]);
Console.WriteLine(response["flag"] + ":" + permissions["ServicePermission"]);
For completeness this would also work with ServiceStack.Text.JsonSerializer:
public class Response
{
public bool flag { get; set; }
public string message { get; set; }
public Permisions result { get; set; }
}
public class Permisions
{
public bool ServicePermission { get; set; }
public bool UserGroupPermission { get; set; }
}
var response = JsonSerializer.DeserializeFromString<Response>(responseFromServer);
Console.WriteLine(response.flag + ":" + response.result.ServicePermission);
if u are using jQuery u can do this
var json=jQuery.parseJSON(responseFromServer);
//acess
alert(json.ServicePermission);
if you are asing microsoft ajax do this
var json=Sys.Serialization.JavaScriptSerializer.deserialize(responseFromServer,true);
//acess
alert(json.ServicePermission);
in c# like php i have'nt seen any method that converts json to object on the fly. To do conversions in c# you must first create a class for this.
For your case you can do like this
//define classes
public class Response
{
public bool flag { get; set; }
public string message { get; set; }
public Permisions result { get; set; }
}
public class Permisions
{
public bool ServicePermission { get; set; }
public bool UserGroupPermission { get; set; }
}
var responseFromServer =
// lines split for readability
"{\"flag\":true,\"message\":\"\",\"result\":{\"ServicePermission\":true,"
+ "\"UserGroupPermission\":true}}";
var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
var responseValue = serializer.Deserialize<Response>(responseFromServer);
//access
responseValue.result.ServicePermission
