Here is my code
I am trying to insert Json values into Azure as Entity, but I always get only the first value when I get back from Azure..Is there anything I need to change in the below code?
string Emulators = "['TestEmulator1','Testemulator12','Testemulator2','TestEmulator3']";
List<string> Emulators = new List<string>();
EmulatorIDS.Add(Emulators);
var jsondata = JsonConvert.SerializeObject(Emulators);
Console.WriteLine(jsondata);
var EmulatorID = new EntityProperty(jsondata);
//Instantiate serializer
Random rnd = new Random();
int a = rnd.Next(1, 1000);
DynamicTableEntity actordata = new DynamicTableEntity();
actordata.RowKey = "Test"+a.ToString();
actordata.PartitionKey = "test#gmail.com";
actordata.Properties["DetailsValue"] = EmulatorID;
actordata.Properties["OtherData"] = EmulatorID;
TableOperation insertOperation = TableOperation.Insert(actordata);
table.Execute(insertOperation);
Have a look https://www.nuget.org/packages/ObjectFlattenerRecomposer/ version 2.0 it will automatically convert your complex objects to a writable form to table storage, it supports complex types and ICollection/IEnumerable type properties as well. You do not need to do any up front json conversion yourself either, the api automatically handles conversions.
If anybody is looking for answer for this..Please see here about how to insert Json values via TableEntity instead of using JsonPayload format

I'm trying to parse some Json in Xamarin.Forms
I'm pretty new to Xamarin, though not to .net
Here's my simple dimple code
var htc = new HttpClient();
var rsp = await htc.GetStringAsync("myurl.com");
JArray lists = JArray.Parse(rsp);
var c = lists.Count();
var l = lists.ToList();
var w=lists.Where(x => true);
Even though c returns the correct count of items in the list, l & w are both null
How come? and how do I fix it?
Thanks!
PS. What I'm really trying to do is bind a ListView to a JArray, but it seems impossible directly,(Text={Binding MyPropertyName} crashes the app). so I'm trying to run a Select on the JArray to convert to a KeyValuePair. If you have any ideas to bind directly, that would be best!
UPDATE
The issue seems even odder
I tried this
var kvlist = new List<KeyValuePair<string, string>>();
foreach (JObject ll in lists)
{
kvlist.Add(new KeyValuePair<string, string>(ll["Name"].ToString(), ll["Name"].ToString()));
}
Here at least the iteration works nicely, but the kvlist is null the entire time. Trying to evaluate the kvlist variable, I get:
Unable to cast object of type 'System.RuntimeType' to type
'Mono.Debugger.Soft.TypeMirror'.
What can the matter be?
Thanks again!
You should not directly call .ToList on object type of JArray rather you should Select List of type you need. For ex.
var l = lists.Select(c => new MyList
{
Item1 = c.Value<int>("ItemName1"),
Item2 = c.Value<string>("ItemName2")
}).ToList(); //Replce MyList with your class name
On the second case where w is null, after getting list l you need to specify attribute, based of what you are using where clause. For ex.
var w=l.Where(x =>x.isAdmin==true); //l is list you selected above
Hope it help you.
Solution:
You can use code below to convert a JArray to a list<T>:
List<T> t =lists.ToObject<List<T>>();
Refer: https://www.newtonsoft.com/json/help/html/ToObjectType.htm
You could also use JsonConvert.DeserializeObject to convert it directly into the desired type. You have to define a jsonModel class with the same structure of your json fisrtly.
List<jsonModel> modelList = JsonConvert.DeserializeObject<List<jsonModel>>(jsonStr);
Refer :https://www.newtonsoft.com/json/help/html/SerializingCollections.htm
The documentation seems to indicate that JArray has properties for .Count, but no overload method because it does not implement IEnumerable, however as alluded to in the comments, it does implement the JToken type (which JArray is a collection of) and implements IEnumerable.
See the following documentation for JToken: https://www.newtonsoft.com/json/help/html/T_Newtonsoft_Json_Linq_JToken.htm
and JArray respectively:
https://www.newtonsoft.com/json/help/html/T_Newtonsoft_Json_Linq_JArray.htm
The preferred mechanism is to create a strong type and then run .ToObject();
You can access JArray.ChildrenTokens which may help
I am working on the requirement where a User can fetch the data from production box and insert it into developer sandbox by just giving production URL and creds. I am able to fetch data but somehow not able to convert the JSON to required object type. As I am newbie in Salesforce please don't mind for basic questions.
Below is the working logic and issue:
for(DataMigrationNAP__c d : dataMigrationNAP) // this loop will give all NAP object names and its corresponding fields like {'Account','Name,Phone,Id'},{'Opportunity', 'ID,Name, blah,blah'}...
{
final PageReference theUrl = new PageReference(SERVER_URL + '/services/data/v22.0/query/');
String soql = 'Select '+d.NAPObjectFields__c+' From '+d.Name+' a limit ' + recordCount;
theUrl.getParameters().put('q',soql);
request = new HttpRequest();
request.setEndpoint(theUrl.getUrl());
request.setMethod('GET');
request.setHeader('Authorization', 'OAuth ' + SESSION_ID);
String body = (new Http()).send(request).getBody();
JSONParser parser = JSON.createParser(body);
do{
parser.nextToken();
}while(parser.hasCurrentToken() && !'records'.equals(parser.getCurrentName()));
parser.nextToken();
String typeName = 'List<' + d.Name + '>';
Type t = Type.forName(typeName);
List<sobject> acc1 = (List<sobject>) parser.readValueAs(t);
insert acc1;
System.debug('Values inserted : ' + acc1);
}
Through above logic I am trying to fetch the data Object by Object and insert it into dev sandbox, I am able to fetch perfectly in JSON but not able to convert from JSON to required object. The issue is I can't hardcode Object or Type name because it will be a list of objects. Please let me know if you need any other detail and thanks in advance. Open for any other approach as well but it should be through apex coding only.
Have you tried JSON2Apex already, if not than this could be good candidate.
I'm using node-orm2 to persist a model to a mysql db column. It works great, except I want the written json pretty printed, so I can easily read it when I view the DB.
Is this possible?
you can use JSON stringify with params:
var obj = {manu: true, gili: "abc"}
var str = JSON.stringify(obj, null, 4); // spacing = 4
I have a JSON file that contains what I believe to be a correct JSON string:
{"title": "exampleTitle", "tipTitle": "exampleTipTitle", "tip": "exampleTip"}
I'm trying to parse said file and take out the 3 values then store them in variables, however currently, it parses each individual character as a separate object, therefore:
JSONobj[1] = "
and so on. Assuming that currentLocation = the directory location of the json file.
Code
var jsonLocation = currentLocation + "json.txt";
var request = new XMLHttpRequest();
request.open("GET", jsonLocation, false);
request.send(null);
var returnValue = request.responseText;
var JSONobj = JSON.parse(JSON.stringify(returnValue));
var headerTitle = JSONobj[0];
A few clarifications, the stringify is in because it was throwing an unexpected token error. I've tried changing the file tile to .json instead but that also makes no difference. "It also gives off a XMLHttpRequest on the main thread is deprecated" but I'm not particularly sure how to solve that issue. Any help would be appreciated.
var returnValue = request.responseText;
Here returnValue is a string of JSON.
"{\"title\": \"exampleTitle\", \"tipTitle\": \"exampleTipTitle\", \"tip\": \"exampleTip\"}
var JSONobj = JSON.parse(JSON.stringify(returnValue));
Here you convert the string of JSON to JSON. So you have a JSON string representing a string, and that string is a representation of a data structure in JSON.
"\"{\\"title\\": \\"exampleTitle\\", \\"tipTitle\\": \\"exampleTipTitle\\", \\"tip\\": \\"exampleTip\\"}"
Then you parse it and convert it back to the original string of JSON.
"{\"title\": \"exampleTitle\", \"tipTitle\": \"exampleTipTitle\", \"tip\": \"exampleTip\"}
So you end up back where you start.
Just don't use JSON.stringify here, and you'll convert your JSON to a JavaScript object:
var javascript_object = JSON.parse(returnValue);
Then you have an object, but it doesn't have a 0 property so it doesn't make sense to access it with javascript_object[0]. The properties have names, such as javascript_object.title.
Your JSON doesn't describe an array, so indexing into it with an index like 0 doesn't make sense. Your JSON describes an object, which will have properties with the names title, tipTitle, and tip.
Additionally, you're overdoing your parsing: You just want to parse, not stringify (which is the opposite of parsing):
var JSONobj = JSON.parse(returnValue);
So:
var JSONobj = JSON.parse(returnValue);
var headerTitle = JSONobj.title;
console.log(headerTitle); // "exampleTitle"
Side note: By the time you've assigned it to the variable you've called JSONobj, it isn't JSON anymore, it's just a normal JavaScript object, so that name is a bit misleading. If you're writing source code, and you're not dealing with a string, you're not dealing with JSON anymore. :-)
This is my first question, so do not judge strictly.
I have an object that I'm getting from php server to as3(flash) client. That object is AMF encoded, so I write server response to ByteArray:
var ba:ByteArray = new ByteArray();
ba.writeUTFBytes( rawData );
and than I'm reading object from ByteArray:
ba.position = 0;
var response:Object = ba.readObject();
Part of object contains such data:
{
'money' : 900
}
And when reading object from ByteArray, I get a seven-digit number ~ 1824344 instead of 900. But when I get form server String '900' or int value equals 100 - data reads correctly.
Has someone had such a problem?
You have to read the same way you wrote. If you write something using writeUTFBytes(), you have to read it using readUTFBytes().
In this case you should use writeObject() and readObject() because you are writing pure Object but not String.
