How to count number of JSON elements of elements in C# - c#

As items has two elements, But I want to count the number of element present in snippet, how can I count, I have parse the json and try to get length as,
dynamic result = JsonConvert.DeserializeObject("jsonStr");
foreach (var res in result.items)
{
int size = res.snippet.count; // Not working
}

(res.snippet as JObject).Count

Slightly different syntax to aspark's solution,
private static void Main(string[] args)
{
string json = #"
{
a: 1,
b: 2,
c: [
{c1: 'asdas', c2:231},
{c1: 'aaaaaa', c2: 100},
{c1: 'x', c2: 83823}
]
}
";
Console.WriteLine(JObject.Parse(json)["c"].Count());
//following also works
Console.WriteLine(o.Property("c").Value.Count());
//both print 3
}

Serialize list to an existing .Json file, using a datagridview

I have a deserialized json file output directly to a DGV, and visible to the end user in a DGV. when they are done using the software and close out, I would like to serialize the updated DGV to my json file.
when I deserialized this json file the code is as follows:
CODE
var v = JsonConvert.DeserializeObject<ToolJson>
(File.ReadAllText(#"\testLibrary.json"));
//set DGV source to our datums
toolDataGridView.DataSource = v.Datums.Cast<IInteresting>
().ToList();
and when the form is closed i want to read the DGV back into my json file, in the exact same format it is already. below is snippet of the json file. all i am doing with the DGV is keeping track of Quantities, last employee used and if the tool needs returned. basically 5 new entries to the json file. top level properties.

Clearing accompanying text, i think i understand where the difficulty lied and indeed it is an exotic datatype we need to Use, unless there Is only one list in the json, in which case you can simply add table to named dataset "Tool" and serialize that, I've included both
public partial class frmWithGrid : Form
{
public frmWithGrid()
{
InitializeComponent();
string myDynamicJSON = "Imagine your testLibraryJson loaded here or later but before next line";
DataTable convertedToTableToolData = ConvertToTableToolData(myDynamicJSON);
dataGridView1.DataSource = convertedToTableToolData;
//dataGridView1.DataMember = we're not storing it in a dataset so we can ignore this one
dataGridView1.AutoGenerateColumns = true;
//TODO: Add bla bla to setup UI of cause, suppose you're able to navigate rows etc.
}
DataTable ConvertToTableToolData(string jsonSource)
{
//TODO: Insert own convertion code here, which seems to be in place
return new DataTable(); // instead of this
}
private void btnUserIsDone_Click(object sender, EventArgs e)
{
//Obviously this shouldn't be directly in an event handler
//Either you have many lists
dynamic x = new ExpandoObject();
var editedTable = (DataTable)dataGridView1.DataSource;
//Will ignore that your OrderQty maybe wasn't originally part of data structure, because it may have been
//and it doesn't change anything with the principle, and adds needless complexity
var propertiesDictionary = (IDictionary<string, object>)x;
propertiesDictionary.Add("Tool", editedTable);
//TODO: Add other sets to json if applicable
string serialized = Newtonsoft.Json.JsonConvert.SerializeObject(x);
//or just one
var ds = new DataSet("Tool");
ds.Tables.Add(editedTable.Clone());
serialized = Newtonsoft.Json.JsonConvert.SerializeObject(ds);
}

Restsharp JSON response search

Handling double quotes in JSON strings

We have an application with knockout and we are facing a problem that some registers in the database have double quotes, which caused JSON parsing to fail.

If you test this json against jsonlint you will see where the problem lies. What is the best way to handle this? I think the way I'm serializing the C# model to JSON is not proper? To do that I use:
var jsonModel = JsonConvert.SerializeObject(Model);
Any help is very appreciated.
EDIT
Issue was fixed. Problem was with the serialization.
I fixed this by using the method HttpUtility.JavaScriptStringEncode
var jsonViewModel = HttpUtility.JavaScriptStringEncode(Json.Encode(Model));
This solved my problem. All I had to do to pass this to knockout was #Html.Raw(jsonViewModel)
Best regards and thanks everyone!

JToken get a specific value

I have following JToken output. How can I retrieve the 'value' here from TenantID which should be 1 in this case?

"type": {

This is my current code :
JToken value;
if (usr.Profile.TryGetValue("tenantid", out value))
{
JObject inner = value["value"].Value<JObject>(); //not working with null error
User.TenantID = (string)value;
}
User.obj = usr.Profile;

I need to check if the tenantID actually exists and then get value, else return null or 0.
You should be able to do:
JObject jObject = JObject.Parse(...);
JToken value = jObject.SelectToken("value");
You parse your object, then the inner contents should be exposed in which you can leverage the SelectToken method to find that specific value.
To build it out a bit, you could potentially do:
public static JToken FindToken<T>(string key, T value)
{
string serialized = NewtonsoftJsonSerializer.Instance.Serialize(value);
var jObject = JObject.Parse(serialized);
var jToken = jObject.SelectToken(key);
if(jToken != null)
return jToken;
return null;
}
I still cannot get the overall picture of your JSON, though have a look at this. It may help you.
var str = #"{
""x"": [{
""value"": 1,
""metadata"": {
""userType"": 0,
""flags"": 8,
""type"": {
""type"":""INT4"",
""name"":""Int"",
""id"": 56
},
""colName"":""TenantID""
}
}
]
}";
var parentJObject = JObject.Parse(str);
var xJArray = (JArray)parentJObject["x"];
// first item in JArray which is the object of interest
// look for the appropriate index of the JObject of your data
var firstJTokenInxJArray = (JObject)xJArray[0];
Console.WriteLine(firstJTokenInxJArray["value"].ToString());
I got what I was looking for :
JToken value;
if (usr.Profile.TryGetValue("tenantid", out value))
{
User.TenantID = (int)value [0] ["value"];
}

How to display JSON Data onto a UITableView

I am using Xamarin.iOS to return a JSON and attempt to place it on a UITableView, however I cannot seem to get it to work, here is what I am attempting to do so far:
Main View Controller
This is how I am returning the JSON
var request = new RestRequest {RootElement = "data", Resource = "/users/self/feed"};
request.AddParameter("access_token", instagramAccessToken);
var client = new RestClient ("https://api.instagram.com/v1");
// Edited Client Execution
client.ExecuteAsync(request, response =>
{
RootObject rootObject = JsonConvert.DeserializeObject<RootObject>(response.Content);
table.Source = new TableSource(rootObject.data);
table.ReloadData();
}
);
TableSource Class
public List<RootObject> Data { get; set; }
protected string cellIdentifier = "TableCell";
public TableSource ()
{
Data = new List<T> ();
}
public TableSource(List<T> data)
{
Data = data;
}
public override int RowsInSection (UITableView tableview, int section)
{
return Data.Count;
}
public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
{
if (OnRowSelected != null) {
OnRowSelected (this, new RowSelectedEventArgs (tableView, indexPath));
}
}
public class RowSelectedEventArgs : EventArgs
{
public UITableView tableView { get; set; }
public NSIndexPath indexPath { get; set; }
public RowSelectedEventArgs(UITableView tableView, NSIndexPath indexPath) : base()
{
this.tableView = tableView;
this.indexPath = indexPath;
}
}
public event EventHandler<RowSelectedEventArgs> OnRowSelected;
public override UITableViewCell GetCell (UITableView tableView, MonoTouch.Foundation.NSIndexPath indexPath)
{
UITableViewCell cell = tableView.DequeueReusableCell (cellIdentifier);
// if there are no cells to reuse, create a new one
if (cell == null)
cell = new UITableViewCell (UITableViewCellStyle.Default, cellIdentifier);
// Edited Text
cell.TextLabel.Text = ((Datum)Data[indexPath.Row]).user.username;
return cell;
}
I didn't really have a concrete method of displaying the JSON on the Table, so I would be pretty open to radical change. BTW the JSON loads on the MainViewController perfectly.
JSON Response
Most of your suggestions don't take into consideration how the JSON looks like so here you go:

After those two Edits I still have two errors:
Error on Main View Controller
Error on Table Source
No need to assign the Data multiple times. Assign the source once and then call ReloadData().
client.ExecuteAsync(request, response =>
{
var rootObject = JsonConvert.DeserializeObject<RootObject>(response.Content);
table.InvokeOnMainThread(() =>
{
table.Source = new TableSource(rootObject.data);
table.ReloadData();
});
}
);
EDIT: It seems there are four items in the Datum field and the last one is null.
https://github.com/sami1971/SimplyMobile/blob/master/iOS/Samples/TwitterSample/Twitter.cs
ToString() override for Datum:
public override string ToString()
{
if (user == null)
{
return "User is null";
}
return user.full_name;
}
For full sample download the project, open iOS/SimplyMobile.iOS.sln and run Samples/TwitterSample.
You should be able to do something like this:
cell.TextLabel.Text = ((Datum)Data[indexPath.Row]).user.username;
you have to reload tableView when all data retrived from url to your dictionary or array.
you can do this like this
[self.Yourtableview reloadData];
