ASP.NET Core Web API - The name 'jsonString' does not exist in the current context

I am using ASP.NET Core Web API. I have this code:
ViewModel (Dto):
public class MandateDto
{
public DateTime DueDate { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public int? MandateId { get; set; }
}
public class TransactionDto
{
public string? RawData { get; set; }
}
EntityMapper:
public class EntityMapper
{
public Mandate FromMandateDtoToMandate(MandateDto mandate)
{
Mandate mandate = new Mandate()
{
DueDate = mandate.DueDate,
StartDate = mandate.StartDate,
EndDate = mandate.EndDate
};
string jsonString = JsonSerializer.Serialize(mandate);
return mandate;
}
public TransactionLog FromMandateDtoToTransactionLog(TransactionDto mandate)
{
return new TransactionLog
{
RawData = jsonString,
};
}
}
MandateService:
public async Task<Mandate> Post(MandateDto mandate)
{
var mapper = new EntityMapper();
var mandate = mapper.FromMandateDtoToMandate(mandate);
var transaction = mapper.FromMandateDtoToTransactionLog(mandate);
try
{
await _unitOfWork.MandateRepository.Insert(mandate);
await _unitOfWork.TransactionRepository.Insert(transaction);
await _unitOfWork.SaveChangesAsync();
}
catch (Exception e)
{
throw new Exception(e.Message);
}
return mandate;
return transaction;
}
As shown in EntityMapper, I want to transfer jsonString from FromMandateDtoToMandate into FromMandateDtoToTransactionLog as in:
RawData = jsonString
I got this error:
Error CS0103 The name 'jsonString' does not exist in the current context
How do I resolve this?
Thanks.

you have to add this line with jsonString otherwise the variable doesn't exist in this scope
public TransactionLog FromMandateDtoToTransactionLog(MandateDto mandate)
{
string jsonString = JsonSerializer.Serialize(mandate); //add this line!
return new TransactionLog
{
RawData = jsonString,
};
}

How to assign Room to an Event for meeting using Microsoft Graph API in a UWP App

I am calling the API for creating a meeting on a fixed date & time. I am using Microsoft Graph API for this. Here is the URL
var url = "https://graph.microsoft.com/v1.0/me/events";
I have taken care of the Authentication part and my code does the following thing to send the JSON response to the API
private async void sendInvites_Click(object sender, RoutedEventArgs e)
{
var httpClient = new System.Net.Http.HttpClient();
System.Net.Http.HttpResponseMessage response;
var url = "https://graph.microsoft.com/v1.0/me/events";
CIBC.Models.SendMeetingInvites.RootObject obj = new CIBC.Models.SendMeetingInvites.RootObject();
CIBC.Models.SendMeetingInvites.Location loc = new CIBC.Models.SendMeetingInvites.Location();
loc.displayName = GlobalVariables.MeetingRoomName;
//loc.RoomEmailAddress = GlobalVariables.meetingRoomEmailID.ToString();
obj.subject = "Maths";
CIBC.Models.SendMeetingInvites.Body body = new CIBC.Models.SendMeetingInvites.Body();
body.content = "Its a booking for follow up meeting";
body.contentType = "HTML";
obj.body = body;
List<CIBC.Models.SendMeetingInvites.Attendee> attens = new List<Models.SendMeetingInvites.Attendee>();
for(int i=0;i<GlobalVariables.NumberOfParticipant.Count;i++)
{
CIBC.Models.SendMeetingInvites.EmailAddress email = new CIBC.Models.SendMeetingInvites.EmailAddress();
CIBC.Models.SendMeetingInvites.Attendee atten = new CIBC.Models.SendMeetingInvites.Attendee();
email.address = GlobalVariables.NumberOfParticipant[i].ParticipantADdress;
atten.emailAddress = email;
atten.type = "Required";
attens.Add(atten);
}
CIBC.Models.SendMeetingInvites.Start start = new CIBC.Models.SendMeetingInvites.Start();
start.dateTime = GlobalVariables.sendMeetingInviteStartDate;
start.timeZone = "UTC";
obj.start = start;
CIBC.Models.SendMeetingInvites.End end = new CIBC.Models.SendMeetingInvites.End();
end.dateTime = GlobalVariables.sendMeetingInviteEndTime;
end.timeZone = "UTC";
obj.end = end;
obj.attendees = attens;
obj.location = loc;
string postBody = Newtonsoft.Json.JsonConvert.SerializeObject(obj);
// var postBody1 = "{'Subject':'Testing Organizer - 12','Location':{'DisplayName':'Some place'}," +
//"'Start': {'DateTime': '2016-07-15T15:00:00.0000000', 'TimeZone':'UTC'}," +
//"'End': {'DateTime': '2016-07-15T15:30:00.0000000', 'TimeZone':'UTC'}," +
//"'Body':{'Content': 'This is a test of Grap API.', 'ContentType':'Text'}," +
//"'IsOrganizer':'False','Organizer':{'EmailAddress': " + "{'Address':'organizer#some.com'} }}";
// var requestString = #"{"subject":"My event","start":{"dateTime":"2017-09-25T07:44:27.448Z","timeZone":"UTC"},"end":{"dateTime":"2017-10-02T07:44:27.448Z","timeZone":"UTC"}}"";
var request = new System.Net.Http.HttpRequestMessage(System.Net.Http.HttpMethod.Post, url);
//Add the token in Authorization header
request.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer",GlobalVariables.Token);
request.Content = new StringContent(postBody, UTF8Encoding.UTF8, "application/json");
response = await httpClient.SendAsync(request);
if (response.IsSuccessStatusCode)
{ }
// return await response.Content.ReadAsStringAsync();
else
{
}
//return "";
}
Here is the class file that I am using to pass to the HTTPResponse Message
namespace CIBC.Models.SendMeetingInvites
{
public class Body
{
public string contentType { get; set; }
public string content { get; set; }
}
public class Start
{
public DateTime dateTime { get; set; }
public string timeZone { get; set; }
}
public class End
{
public DateTime dateTime { get; set; }
public string timeZone { get; set; }
}
public class Location
{
public string displayName { get; set; }
//public string RoomEmailAddress { get; set; }
}
public class EmailAddress
{
public string address { get; set; }
public string name { get; set; }
}
public class Attendee
{
public EmailAddress emailAddress { get; set; }
public string type { get; set; }
}
public class RootObject
{
public string subject { get; set; }
public Body body { get; set; }
public Start start { get; set; }
public End end { get; set; }
public Location location { get; set; }
public List<Attendee> attendees { get; set; }
}
}
My requirement is to send a meeting invite to all the users and also mentioning the Room Details like Name& Email ID of the room.
I tried adding a RoomEmail address in the Request as under The Location class
public string RoomEmailAddress { get; set; }
When I tested this using Microsoft Graph Explorer website , i got the error message
{
"error": {
"code": "RequestBodyRead",
"message": "The property 'RoomEmailAddress' does not exist on type 'Microsoft.OutlookServices.Location'. Make sure to only use
property names that are defined by the type or mark the type as open
type.",
"innerError": {
"request-id": "1883d87d-a5d6-4357-a699-7c112da0e56b",
"date": "2017-09-26T12:03:50"
}
} }
How do I make sure that whenever I create a meeting request , I can assign a room to it?
Currently I am just able to pass DisplayName while sending the Request to the URL.
Once I remove the Email Address property (I added myself ), the code returns Success.
Any workarounds so that I can send the room email address also so that the room also receives a copy of the meeting invite ?

Add the room as an attendee with "type": "Resource". Then add the room's display name in the location property.

How to send a model which consist generic list from ajax call in mvc C#

I am trying to call the controller from ajax and sending model data which consist some list of data inside it. I am getting the count correct for them but inside the list properties are coming null.
Controller:
public JsonResult InsertorUpdate(IncidentEdit incident)
{
try
{
SrvincidentDtls.TicketNo = incident.TicketNo;
SrvincidentDtls.Priority = incident.Priority;
SrvincidentDtls.Status = incident.Status;
SrvincidentDtls.Title = incident.Title;
SrvincidentDtls.IsActive = incident.IsActive;
List<Comments> lstComm = new List<Comments>();
if(incident.CommentList!=null )
{
foreach (var comm in incident.CommentList)
{
Comments Comm = new Comments();
Comm.Comment = comm.Comments;
Comm.AddedBy = comm.AddedBy;
Comm.AddedBy_ID = comm.AddedBy_ID;
Comm.CreatedDate = comm.CreatedDate;
lstComm.Add(Comm);
}
}
SrvincidentDtls.Comments = lstComm.ToArray();
SrvincidentDtls.Description = incident.Description;
var result=proxyService.InsertorUpdateIncidentDetails(SrvincidentDtls);
return Json(new { success = true, jvalue = result }, JsonRequestBehavior.AllowGet);
}
catch(Exception ex)
{
throw ex;
}
}
Model:
public class IncidentEdit
{
public string Title { get; set; }
public string Description { get; set; }
public bool IsActive { get; set; }
public string Status { get; set; }
public string Priority { get; set; }
public List<IncidentComments> CommentList { get; set; }
}
Generic Class:
public class IncidentComments
{
public string Comments { get; set; }
public string AddedBy { get; set; }
public string AddedBy_ID { get; set; }
public DateTime CreatedDate { get; set; }
}
Ajax call:
function InsertOrUpdate(){
incidentDetails = {
Title: $("#txtTitle").val(),
Description: $("#txtDescription").val(),
Priority: $('#selPriority option:selected').val(),
Status: $('#selStatus option:selected').val(),
IsActive: 1,
CreatedDate :$('#spncrtdDt').text(),
CommentList:PopulateCommentList()
};
$.ajax({
type: "Get", //HTTP POST Method
url: insertORupdatUrl, // Controller/View
data: {incident:incidentDetails},
contentType: "application/json; charset=utf-8",
success: function (data) {
}
});
}
js function:
function PopulateCommentList() {
var CommentList = [];
var dtTable = $('#dvCommentTbl').DataTable();
for (var i = 0; i < 10; i++) {
if (dtTable.row(i).data() != "" && dtTable.row(i).data() != null && dtTable.row(i).data() != undefined) {
CommentList.push({
Comments: dtTable.row(i).data()[1],
AddedBy: dtTable.row(i).data()[2],
AddedBy_ID: dtTable.row(i).data()[0],
CreatedDate: dtTable.row(i).data()[3]
});
}
}
return CommentList;
}
the count for comment list is coming fine but the data like Added_By,comments,Created Dtae all coming null.
Plz help.

You can take a variable like
var commlist=PopulateCommentList();
then populate it in your model json:
incidentDetails = {
Title: $("#txtTitle").val(),
Description: $("#txtDescription").val(),
Priority: $('#selPriority option:selected').val(),
Status: $('#selStatus option:selected').val(),
IsActive: 1,
CreatedDate :$('#spncrtdDt').text(),
CommentList:commlist
};
it will work as it work for me.

Request.CreateResponse returns blank data to postman

I have encountered a problem when trying to call my web api with a post request, a empty array is returned.
My method is:
// POST: Api/v1/transaction/
[HttpPost]
public HttpResponseMessage Post(string user)
{
var userId = new Guid(user);
var transactions = new Collection<TransactionDataTransferObject>();
try
{
var seller = _databaseContext.Sellers.Single(s => s.Id == userId);
var sellerMedias = _databaseContext.Medias.Where(m => m.TakenBy.Id == seller.Id);
foreach (var sellerMedia in sellerMedias)
{
var allLogsForMedia = _databaseContext.Logs.Where(l => l.ObjectReferenceId == sellerMedia.Id);
foreach (var logMedia in allLogsForMedia)
{
var transaction = new TransactionDataTransferObject
{
Date = logMedia.DateTimeInUtc,
Amount = sellerMedia.PriceInSek,
MediaName = sellerMedia.FileName,
UserName = seller.FirstName + " " + seller.LastName
};
transactions.Add(transaction);
}
}
}
catch (Exception exception)
{
return Request.CreateErrorResponse(HttpStatusCode.NotFound, exception);
}
return Request.CreateResponse(HttpStatusCode.OK, transactions);
}
When I debug transactions variable, I see two objects in the collection.
My response to postman is
[
{},
{}
]
What have I done wrong? Where is my data which is sent?

Ok, after some hours of slaming my head in the table i found out that I used
[DataContract] as filter on the ViewModel,TransactionDataTransferObject.
Like this:
[DataContract]
public class TransactionDataTransferObject
{
[Display(Name = "Date")]
public DateTime Date { get; set; }
public string MediaName { get; set; }
public Guid MediaId { get; set; }
public string UserName { get; set; }
public Guid UserId { get; set; }
[Display(Name = "Description")]
public string Discriminator { get; set; }
[Display(Name = "Amount")]
public decimal Amount { get; set; }
}
Which was wrong in this case...
Thanks for reading!

How to properly use javascript deserialization to convert a json string to a complex object?

I have the following json object that is available in my .ashx handler (var items=):
{"Coverages":{"PersonID":10,"DetCode":"","Reimbursement":"","Deductible":"","MaximumPerAnnum":"","MaximumPerVisit":"","MaximumPerVisits":"","SvcCode":""},"CoverageCombinedMaximums":{"PersonID":10,"DetCode":["AAAAA","BBBBB","CCCCC"],"MaximumPerAnnum":""}}
public void ProcessRequest (HttpContext context) {
bool isSuccessful = true;
var items = context.Request.Params["items"];
if (isSuccessful)
{
JavaScriptSerializer ser = new JavaScriptSerializer();
AdditionalCoveragesPackage package = ser.Deserialize<AdditionalCoveragesPackage>(items);
}
else
{
SendErrorMessage(context);
return;
}
}
Here is the structure of the class I'm trying to deserialize:
public class AdditionalCoverage
{
public int PersonID { get; set; }
public string DetCode { get; set; }
public decimal? Reimbursement { get; set; }
public decimal? Deductible { get; set; }
public decimal? MaximumPerAnnum { get; set; }
public decimal? MaximumPerVisit { get; set; }
public int? MaximumPerVisits { get; set; }
public string SvcCode { get; set; }
public AdditionalCoverage()
{
}
}
public class AdditionalCoverageCombinedMaximum
{
public int PersonID { get; set; }
public string SvcCode { get; set; }
public decimal? MaximumPerAnnum { get; set; }
public List<string> DetCode { get; set; }
public AdditionalCoverageCombinedMaximum()
{
}
}
public class AdditionalCoveragesPackage
{
public List<AdditionalCoverage> Coverages { get; set; }
public List<AdditionalCoverageCombinedMaximum> CoverageCombinedMaximums { get; set; }
public AdditionalCoveragesPackage()
{
}
public AdditionalCoveragesPackage(AdditionalCoverage coverage, AdditionalCoverageCombinedMaximum maximum)
{
List<AdditionalCoverage> coverages = new List<AdditionalCoverage>();
coverages.Add(coverage);
Coverages = coverages;
List<AdditionalCoverageCombinedMaximum> maximums = new List<AdditionalCoverageCombinedMaximum>();
maximums.Add(maximum);
CoverageCombinedMaximums = maximums;
}
public AdditionalCoveragesPackage(List<AdditionalCoverage> coverages, List<AdditionalCoverageCombinedMaximum> maximums)
{
Coverages = coverages;
CoverageCombinedMaximums = maximums;
}
}
Edit: Here are my client side methods that need correction:
function saveCoverageDetails() {
var handler = "HttpHandlers/UpdateAdditionalCoverageDetailsHandler.ashx";
var coverages = { PersonID: personId, DetCode: "", Reimbursement: "", Deductible: "", MaximumPerAnnum: "", MaximumPerVisit: "", MaximumPerVisits: "", SvcCode: "" };
var maximums = { PersonID: personId, DetCode: ["ACUPUN", "PODIAT", "OSTEOP"], MaximumPerAnnum: "" };
var obj = { Coverages: coverages, CoverageCombinedMaximums: maximums };
var data = ({ items: JSON.stringify(obj) });
callHandler(handler, data, saveSuccessful, failure);
}
function callHandler(handler, obj, onSuccess, onFail) {
$.ajax({
type: "POST",
url: handler,
data: obj,
dataType: "json",
success: onSuccess,
fail: onFail
});
}
When I'm using the javascript serializer it does return my AdditionalCoveragesPackage object - however - both of the properties: Coverages and CombinedMaximums are empty. How to get this to properly deserialize my json string?

In your JSON string Coverages and CoverageCombinedMaximums are simple objects, not arrays, so:
public class AdditionalCoveragesPackage
{
public AdditionalCoverage Coverages { get; set; }
public AdditionalCoverageCombinedMaximum CoverageCombinedMaximums { get; set; }
}
Also in your example JSON:
"MaximumPerAnnum":""
so make sure you define the corresponding property as a nullable decimal:
public decimal? MaximumPerAnnum { get; set; }
or the deserializer will blow.

The Coverages and CombinedMaximums properties in your JSON are objects, not arrays.
You should change those to arrays or change your C# class to not use List<T>s.

SLAKS and Darin Dimitrov both helped a ton. Ends up it works if I compose my JSON string as below (I had the array structured incorrectly and was passing empty strings instead of zeros for my numeric types). Here's the corrected client code:
var handler = "HttpHandlers/UpdateAdditionalCoverageDetailsHandler.ashx";
var coverages = [{ PersonID: personId, DetCode: "", Reimbursement: 0, Deductible: 0, MaximumPerAnnum: 0, MaximumPerVisit: 0, MaximumPerVisits: 0, SvcCode: "" }, { PersonID: personId, DetCode: "CHIROP", Reimbursement: 0, Deductible: 0, MaximumPerAnnum: 0, MaximumPerVisit: 0, MaximumPerVisits: 0, SvcCode: ""}];
var maximums = [{ PersonID: personId, DetCode: ["ACUPUN", "PODIAT", "OSTEOP"], MaximumPerAnnum: 0 }, { PersonID: personId, DetCode: ["ACUPUN", "PODIAT", "OSTEOP"], MaximumPerAnnum: 0}];
var obj = { Coverages: coverages, CoverageCombinedMaximums: maximums };
var data = ({ items: JSON.stringify(obj) });
callHandler(handler, data, saveSuccessful, failure);
