How to deserialize with keyvaluepair the above json
string stations = [{"2":false,"1":"Aforre","0":"WS6"},{"2":false,"1":"Alodtau","0":"WS3"},{"2":false,"1":"Balimo Station","0":"WS36"}]
I what like this
var get = js.Deserialize<Dictionary<string,dynamic>>(stations);
try this:
string stations = "[{'2':false,'1':'Aforre','0':'WS6'},{'2':false,'1':'Alodtau','0':'WS3'},{'2':false,'1':'Balimo Station','0':'WS36'}]";
var serializer = new JavaScriptSerializer();
dynamic value = serializer.DeserializeObject(stations);
and you can access objects like:
var a = value[0]["0"];
and a will have "WS6" (according to your JSON)
The JSON shown is an array. You might try desetializing to:
Dictionary<string, object>[]
i.e.
var get = js.Deserialize<Dictionary<string,object>[]>(stations);
One of the best option is create a class that consist of all keyvalue pair and then deserialize json string to the object of created class
You can try using dynamic variable as following:
string stations = "[{'2':false,'1':'Aforre','0':'WS6'},{'2':false,'1':'Alodtau','0':'WS3'},{'2':false,'1':'Balimo Station','0':'WS36'}]";
var serializer = new JavaScriptSerializer();
dynamic serializevalues = serializer.DeserializeObject(stations);
var valueof1 = serializevalues[0]["1"];
Response.Write(valueof1);
The above will print output "Aforre'.

I am getting the json (objArr) object using the following code:
var objArr = (object[])record.Value;
The code at runtime looks like this:
The json object objArr contains the list of rows, how can I retrieve the properties of rows?
I am able to list the properties with the following loop:
foreach (var obj in objArr)
{
foreach(var item in (Dictionary<string, object>)obj)
{
}
}
but I want to retrieve the properties directly from objArr
try this according to your onject specification
JavaScriptSerializer js = new JavaScriptSerializer();
BlogSites blogObject = js.Deserialize<BlogSites>(jsonData);
string name = blogObject.Name;
string description = blogObject.Description;
// Other way to whithout help of BlogSites class
dynamic blogObject = js.Deserialize<dynamic>(jsonData);
string name = blogObject["Name"];
string description = blogObject["Description"];

My question is simple but i can not do that. i wanna get value of "soap:Body" from below string by C#code?
{"soap:Envelope":{"xmlns:xsd":"http://www.w3.org/2001/XMLSchema","xmlns:soap":"http://www.w3.org/2003/05/soap-envelope","xmlns:xsi":"http://www.w3.org/2001/XMLSchema-instance","soap:Body":{"ToplamaResponse":{"xmlns":"http://tempuri.org/","ToplamaResult":156758}}}}
You can also use the Framework class JavaScriptSerializer if you do not want to use an external library.
string json = #"...";
JavaScriptSerializer serializer = new JavaScriptSerializer();
var o = serializer.Deserialize<dynamic>(json);
var body = o["soap:Envelope"]["soap:Body"];
You can do it easily by using Json.NET
dynamic data = JObject.Parse("{'soap:Envelope':{'xmlns:xsd':'http://www.w3.org/2001/XMLSchema','xmlns:soap':'http://www.w3.org/2003/05/soap-envelope','xmlns:xsi':'http://www.w3.org/2001/XMLSchema-instance','soap:Body':{'ToplamaResponse':{'xmlns':'http://tempuri.org/','ToplamaResult':156758}}}}");
string soap_body = data["soap:Envelope"]["soap:Body"];
There is a simple example in the JObject.Parse documentation
string json = #"{
"soap:Envelope": {
"xmlns:xsd": "http://www.w3.org/2001/XMLSchema",
"xmlns:soap": "http://www.w3.org/2003/05/soap-envelope",
"xmlns:xsi": "http://www.w3.org/2001/XMLSchema-instance",
"soap:Body": {
"ToplamaResponse": {
"xmlns": "http://tempuri.org/",
"ToplamaResult": 156758
}
}
}
}";
JObject obj = JObject.Parse(json);
Console.WriteLine((string)obj["soap:Envelope"]["soap:Body"]);
And if you want to manipulate the value of "soap:Body" do the same thing :)

I am trying to read all the values from json object and put it in the list of string , for which I am doing Json deserialize but it throws me error...
Here is what I have tried
List<string> lstPName = new List<string>();
JavaScriptSerializer strJsonSer = new JavaScriptSerializer();
localhost.Pstats objStats = new localhost.Pstats();
var strJson = objStats.GetAutoCompleteData(txtSearchBox.Text.Trim());
lstPName = strJsonSer.DeserializeObject<string>(strJson);
Here is what the Json object holds
[{"PlayerName":"WA Mota"},{"PlayerName":"Atif Ahmed"}]
So, I need the player name value to be added in the list...
Simple and straightforward solution:
var strJson = "[{\"PlayerName\":\"WA Mota\"},{\"PlayerName\":\"Atif Ahmed\"}]";
var strJsonSer = new JavaScriptSerializer();
var list = new List<string>();
var result = strJsonSer.DeserializeObject(strJson) as object[];
if (result != null)
{
foreach (Dictionary<string, object> x in result)
{
list.Add(x["PlayerName"].ToString());
}
}
Or, if you are preferring LINQ - you can use instead of foreach loop something like:
list = result
.Cast<Dictionary<string, object>>()
.Select(x => x["PlayerName"].ToString())
.ToList();
Key idea: DeserializeObject used for parsing JSON data like yours gives you array of Dictionary<string, object> where key is JSON property name and value is JSON property value. Size of array equals to objects count in your JSON data.
Using mvc i get values like this to avoid class declarations and router changes.
public dynamic Create([FromBody] dynamic form)
{
var username = form["username"].Value;
var password = form["password"].Value;
var firstname = form["firstname"].Value;
...
I like to iterate through all values and check them for null or empty.
If you get a json from the argument, you could convert it to an Dictionary<string, dynamic> where the string key is the name of the property and the dynamic is a value that can assume any type. For sample:
var d = JsonConvert.DeserializeObject<Dictionary<string, dynamic>>(form);
var username = d["username"];
You also could loop between Keys property from the Dictionary<>:
foreach(var key in d.Keys)
{
// check if the value is not null or empty.
if (!string.IsNullOrEmpty(d[key]))
{
var value = d[key];
// code to do something with
}
}
This is quite old, but I came across this and am wondering why the following was not proposed:
var data = (IDictionary<string, object>)form;
You can use JavaScriptSerializer and dynamic object:
JavaScriptSerializer serializer = new JavaScriptSerializer();
dynamic myDynamicObject = serializer.DeserializeObject(json);
For example, if you want to loop through myDynamicObject["users"]:
foreach (KeyValuePair<string, dynamic> user in myDynamicObject["users"]){
Console.WriteLine(user.Key+": "+user.Value["username"]);
Console.WriteLine(user.Key+": "+user.Value["email"]);
}
I am trying to deserialize an instance of the following class from a JSON string using JavaScriptSerializer:
public class Filter
{
public HashSet<int> DataSources { get; set; }
}
Here is the code I am trying out:
Filter f = new Filter();
f.DataSources = new HashSet<int>(){1,2};
string json = (new JavaScriptSerializer()).Serialize(f);
var g= (new JavaScriptSerializer()).Deserialize<Filter>(json);
It errors out with the following message:
Object of type 'System.Collections.Generic.List1[System.Int32]'
cannot be converted to type
'System.Collections.Generic.HashSet1[System.Int32]'.
Apparently, the serializer is unable to distinguish between a list and set from JSON representation. What is the solution to this?
Note : I would prefer avoiding the use of external libraries due to constraints at work.
What is the solution to this?
Use Json.Net. This code works...
Filter f = new Filter();
f.DataSources = new HashSet<int>() { 1, 2 };
string json = JsonConvert.SerializeObject(f);
var g = JsonConvert.DeserializeObject<Filter>(json);
EDIT
DataContractJsonSerializer seems to work too...
DataContractJsonSerializer dcjs = new DataContractJsonSerializer(typeof(Filter));
var g2 = dcjs.ReadObject(new MemoryStream(Encoding.UTF8.GetBytes(json))) as Filter;
Here's my simple NOT so great solution, but it works.
var dataList = new JavaScriptSerializer().Deserialize<List<int>>(returnData);
var data = new HashSet<int>(dataList);
