I'm working in C#.net in a WebAPI...
I have...
WebAPI Controller...
public class GetSMBController : ApiController
{
public HttpResponseMessage GET(int AgencyID, string UserName)
{
var Pdfs = new HttpResponseMessage();
Pdfs = Utilities.Reporting.CreateStandardMapBooklet(AgencyID,UserName);
return Pdfs;
}
}
That calls a method...
public static HttpResponseMessage CreateStandardMapBooklet(int AgencyID, string userName)
{
string baseDataPath = #"\\dvfmweb4\\arcgisserver\basedata\";
string tempDataPath = #"\\dvfmweb4\arcgisserver\tempGrowerData\";
string unitTestSession = "UnitTestSession";
int ShadeType = 1;
bool isInImagery = false;
double MaxSceneSize = 1.5;
bool ScaleBar = true;
int MapSettingID = 0;
bool OverallPage = false;
bool OverallImagery = false;
bool IsRecordKeepingSheet = false;
int RecordKeepingSheetID = 0;
int TemplateID = 1480;
RCIS.Mapping.MapDomain.Reports.StandardMapBookletReport _Pdfs = new RCIS.Mapping.MapDomain.Reports.StandardMapBookletReport(
baseDataPath,
tempDataPath,
unitTestSession,
AgencyID,
ShadeType,
isInImagery,
MaxSceneSize,
ScaleBar,
MapSettingID,
TemplateID,
OverallPage,
OverallImagery,
false,
RecordKeepingSheetID,
userName,
true);
PDF testPDF = new PDF();
byte[] test = null;
try
{
List<RCIS.Mapping.MapDomain.Layout.CreatePdfResponse> pdf = _Pdfs.CreateReports();
foreach (var item in pdf)
{
//PDFInfo info = new PDFInfo();
//info.PdfBytes = item.PdfBytes;
testPDF.Report = item.PdfBytes;
test = item.PdfBytes;
}
}
catch(Exception e)
{
}
var response = new HttpResponseMessage(HttpStatusCode.OK)
{
Content = new ByteArrayContent(test)
};
response.Content = new ByteArrayContent(test);
response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/pdf");
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("inline")
{
FileName = String.Format(AgencyID + userName + DateTime.Now.ToString("MMMddyyyy_HHmmss"))
};
response.Headers.CacheControl = new CacheControlHeaderValue()
{
MaxAge = new TimeSpan(0, 0, 60) // Cache for 30s so IE8 can open the PDF
};
return response;
}
Sorry for some of the commented out stuff and goofy variable names...I'm just trying to see if this is a viable thing.
the test object and HttpResponse message Content ARE populated but
I'm receiving this error when I call this from a browser...
This XML file does not appear to have any style information associated with it. The document tree is shown below.

I tried to execute my application Rest api. Using a breakpoint, I found a problm in this line:
expenses.AmountTTC = Convert.ToDecimal(ttc.Text);
The error is "Specified cast is not valid".
AmountTTC has the type decimal? in the model , same for my service(i have two projects, one for the services and anthor for my mobile application).
private void Button_Clicked(object sender, EventArgs e)
{
ajoutD.Clicked += async delegate
{
try
{
LoginViews expenses = new LoginViews();
expenses.Name = nameLib.Text;
expenses.StartDate = dataDe.Date;
expenses.EndDate = dateAu.Date;
datenow.Date = DateTime.Now;
expenses.Description = description.Text;
expenses.CurrencyId = Convert.ToInt32(devises.Id);
expenses.AmountTTC = Convert.ToDecimal(ttc.Text);
remb.Text = expenses.AmountReimbursed.ToString();
expenses.Remboursable = Convert.ToBoolean(isremboursable);
expenses.Provider = marchand.Text;
HttpClient httpClient = new HttpClient();
HttpResponseMessage response;
var json = JsonConvert.SerializeObject(expenses);
var content = new StringContent(json, Encoding.UTF8, "application/json");
response = await httpClient.PostAsync(url, content);
AuthResponse responseData = JsonConvert.DeserializeObject<AuthResponse>(response?.Content?.ReadAsStringAsync()?.Result);
if (responseData.data.Success)

}
else
{
await DisplayAlert("wake up !", responseData.data.ErrorMessage, "attention");
}
}catch(Exception eee)
{
string msg = eee.ToString();
}
};
}
I have tried many solutions for this simple error but I couldn't find bug what actually cause it.
Here is some code for reference.
GPController
[HttpPost("testConnection")]
public bool TestConnection()
{
try
{
var data = eConn.GetEntity();
if (data)
{
return true;
}
return false;
}
catch(Exception ex)
{
throw ex;
}
}
eConn.cs
public static bool GetEntity()
{
try
{
string connString = DataAccess.ConnectionString;
eConnectOut myRequest = new eConnectOut();
myRequest.DOCTYPE = "Customer";
myRequest.OUTPUTTYPE = 1;
myRequest.INDEX1FROM = "Customer001";
myRequest.INDEX1TO = "Customer001";
myRequest.FORLIST = 1;
// Create the eConnect requester XML document object
RQeConnectOutType[] eConnectOutType =
new RQeConnectOutType[1] { new RQeConnectOutType()};
eConnectOutType[0].eConnectOut = myRequest;
eConnectType eConnectDoc = new eConnectType();
eConnectDoc.RQeConnectOutType = eConnectOutType;
// Serialize the object to produce an XML document
MemoryStream memStream = new MemoryStream();
XmlSerializer serializer = new XmlSerializer(typeof(eConnectType));
serializer.Serialize(memStream, eConnectDoc);
memStream.Position = 0;
XmlDocument myDoc = new XmlDocument();
myDoc.Load(memStream);
eConnectMethods eConnCall = new eConnectMethods();
eConnCall.RequireProxyService = false;
// Retrieve the specified customer document
string myCustomer = eConnCall.GetEntity(connString, myDoc.OuterXml);
return true;
}
catch(Exception ex)
{
throw ex;
}
}
In eConn.cs calling GetEntity method I am getting this error.
{System.NullReferenceException: Object reference not set to an instance of an object.

For some reason the video keeps returning null and i can't figure out , i have tried everything i really need help with this project.
I want to create a registrant for a webinar using GoToWebinar API's. I came across the code at gotowebinar api php
I provided my username and password to get the oAuth object. This worked perfectly fine as described.
Now I want to do something like this:
I have a Registration page. When user fills in the required details, selects the 'register to webinar' option and clicks on 'Submit', I want to enrol him for that webinar using CreateRegistrant API. The problem is, I am not able to get the oAuth object without providing username and password. Is there a way to pass this programatically and create oAuth object?
I store my API key, UserID and password in my WebConfig then read them into a Login Object for use when I do authorization. Here's how I do it in C#:
public class Login
{
public string UserId
{ get { return System.Configuration.ConfigurationManager.AppSettings["GTWUserId"]; } }
public string Password
{ get { return System.Configuration.ConfigurationManager.AppSettings["GTWPassword"]; } }
public string APIKey
{ get { return System.Configuration.ConfigurationManager.AppSettings["GTWAPIKey"]; } }
}
public string DoAuthorize()
{
Login lg = new Login();
string sError = "";
// first we need to create the uri for the web request
string uri = String.Format("https://api.citrixonline.com/oauth/access_token?grant_type=password&user_id={0}&password={1}&client_id={2}",
lg.UserId, lg.Password, lg.APIKey);
// then the request to login is created and sent. From the response
// we need to store at least the access token and the organizer key
// to use for further calls
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
request.Accept = "application/json";
request.ContentType = "application/json";
try
{
var response = request.GetResponse();
//the following lines duplicate the response stream so we can read it for
//deserialization and also re-read it and write it out.
using (MemoryStream ms = new MemoryStream())
{
var stream = response.GetResponseStream();
stream.CopyTo(ms);
ms.Position = 0;
stream.Close();
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(ResponseDirectLogin));
var deserialized = (ResponseDirectLogin)ser.ReadObject(ms);
auth.OauthToken = deserialized.AccessToken;
auth.OrganizerKey = deserialized.OrganizerKey;
}
}
catch (WebException e)
{
using (var sr = new StreamReader(e.Response.GetResponseStream()))
sError = sr.ReadToEnd();
sError = String.Concat(sError, "/n", uri);
}
return sError;

public class Auth {
public string OauthToken { get; set; }
