How to convert azure vision output in string Json to previous object?

I have converted the input image into OCRResults by using these codes.

Thread.Sleep(2000);
// Retrieve the URI where the extracted text will be stored from the Operation-Location header.
// We only need the ID and not the full URL
const int numberOfCharsInOperationId = 36;
string operationId = operationLocation.Substring(operationLocation.Length - numberOfCharsInOperationId);
// Extract the text
ReadOperationResult results;
Console.WriteLine($"Extracting text from URL file {Path.GetFileName(urlFile)}...");
Console.WriteLine();
do
{
results = await client.GetReadResultAsync(Guid.Parse(operationId));
}
while ((results.Status == OperationStatusCodes.Running ||
results.Status == OperationStatusCodes.NotStarted));
// Display the found text.
Console.WriteLine();
var textUrlFileResults = results.AnalyzeResult.ReadResults;
foreach (ReadResult page in textUrlFileResults)
{
foreach (Line line in page.Lines)
{
Console.WriteLine(line.Text);
}
}
Console.WriteLine();
}
}
}
If I converting the output from the azure vision into json.Is any possibilities convert the json to previous object?

How to generate a hash for my Android app?

I'm using this guide to implement an autocomplete funcionality in an app I'm working on, but when I try to test it in different computers it returns me a different hash https://www.c-sharpcorner.com/article/verify-otp-automatically-in-android-without-sms-read-permission-using-xamarin-fo/
The helper class used is the following:
using System.Text;
using Android.Content;
using Android.Content.PM;
using Android.Util;
using Java.Security;
using Java.Util;
namespace InteliMobile.App.Droid.Service
{
public class AppHashKeyHelper
{
private static string HASH_TYPE = "SHA-256";
private static int NUM_HASHED_BYTES = 9;
private static int NUM_BASE64_CHAR = 11;
private static string GetPackageSignature(Context context)
{
var packageManager = context.PackageManager;
var signatures = packageManager.GetPackageInfo(context.PackageName, PackageInfoFlags.Signatures).Signatures;
return signatures.First().ToCharsString();
}
public static string GetAppHashKey(Context context)
{
string keystoreHexSignature = GetPackageSignature(context);
string appInfo = context.PackageName + " " + keystoreHexSignature;
try
{
var messageDigest = MessageDigest.GetInstance(HASH_TYPE);
messageDigest.Update(Encoding.UTF8.GetBytes(appInfo));
byte[] hashSignature = messageDigest.Digest();
hashSignature = Arrays.CopyOfRange(hashSignature, 0, NUM_HASHED_BYTES);
string base64Hash = Android.Util.Base64.EncodeToString(hashSignature, Base64Flags.NoPadding | Base64Flags.NoWrap);
base64Hash = base64Hash.Substring(0, NUM_BASE64_CHAR);
return base64Hash;
}
catch (NoSuchAlgorithmException e)
{
return null;
}
}
}
}
How can I get the hash without using a bash script, since the server runs in a Windows machine? Is it safe to deploy the app to production with the helper class in it?

You don't compute the hash client side. It's sent from the server, and the instructions to do so are at https://developers.google.com/identity/sms-retriever/verify#computing_your_apps_hash_string
You don't do it in code at all, you do it via command line tools.

Hadoop task is cancelled due to task timeout

I am writing a C# mapreduce program that runs on the cluster. The system returns an error of
System.Threading.Tasks.Task
The task is cancelled after a timeout of 32 milliseconds. The data is pretty huge .I even changed the data size to check but the error still occurs, so I am assuming it is not due to the data size.
Is there a way to change the task timeout of 32 milliseconds.
I am using Azure, Visual studio 2013 and a cluster with 4 nodes.
The system aggregate exception occured in mscorlib.dll

Inputting values to a string as a website URL for the page to be downloaded

I'm messing around with the System.Net library in C# and I'm trying to simply have it set up such that you enter an url and it will take that as a string and put that into the parameter for the URl in the Client.DownloadString() field.
Here is my code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
namespace StringDownloadTest
{
class GetInformation
{
string EnterString;
public string InputString()
{
EnterString = Console.ReadLine();
return EnterString;
}
}
class DownloadString
{
static void Main(string[] args)
{
GetInformation R = new GetInformation();
R.InputString();
string downloadedString;
System.Net.WebClient client;
client = new System.Net.WebClient();
downloadedString = client.DownloadString(R.InputString());
Console.WriteLine("String: {0}", downloadedString);
}
}
}
Any help here, it will compile but the program crashes.

You're calling R.InputString twice and only entering input for the first time.
Try:
GetInformation R = new GetInformation();
Console.WriteLine("Please enter a valid url protocol://domain");
var input = R.InputString();
Uri uri;
if(!Uri.TryCreate(input, UriKind.Absolute, out uri))
{
Console.WriteLine("Url format could not be determined for {0}", input);
Environment.Exit(1);
}
var client = new System.Net.WebClient();
var downloadedString = client.DownloadString(uri);
Console.WriteLine("String: {0}", downloadedString);

c# ews login error

Summary:
I need to login to my mailbox using EWS and but i keep getting 440/401 error.
question:
Anything obvious in my code as to why I keep getting either 401 or 440 errors?
Code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using Microsoft.Exchange.WebServices;
using Microsoft.Exchange.WebServices.Data;
using Microsoft.Exchange.WebServices.Autodiscover;
namespace MailboxListenerEWS
{
class Program
{
//Authentication to exchange 2007 with webdav and filebasedauth (FBA) in C#
//can hardcode a username to connect a mailbox with
internal static string dUser = "username";//username to log into email account
internal static string dDomain = "domain";//domain of username used
internal static string dPassword = "Password";//password of username used
internal static string MailBoxAliasName = "mailboxname";//mailbox to authenticate too
internal static string ExchangeServerName = "exchangeName"; //not always needed
internal static string ReadAttachments = "0"; //1 means read attachments, 0 means dont
internal static string MailBoxEarliestDateToRead = "2011-01-05T00:00:00.000Z";//date of emails to read from
static void Main(string[] args)
{
//Connect to server
//ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
//service.Credentials = new NetworkCredential("name", "pwd", "domain");
service.Credentials = new NetworkCredential("dUser", "dPassword", "dDomain");
//log in to mailbox
try
{
//service.Url = new Uri(serviceurl);
//Console.WriteLine(serviceurl);
//service.AutodiscoverUrl(MailBoxAliasName);
service.Url = new Uri("https://" + ExchangeServerName + "/EWS/" + MailBoxAliasName + "/inbox");
}
catch (AutodiscoverRemoteException ex)
{
Console.WriteLine("Exception thrown: " + ex.Error.Message);
Console.ReadLine();
}
//List folders
try
{
//Listing all the subfolders of the Inbox
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(int.MaxValue));
foreach (Item item in findResults)
{
Console.WriteLine(item.Subject);
}
}
catch (Exception ex)
{
Console.WriteLine("Exception thrown: " + ex.Message);
Console.ReadLine();
}
}
}
}

Are you sure your server uses 2007 SP1? Also, if you're not sure of the correct URL, try using the AutoDiscover, where "user#domain.com" is an actual email address on your domain.
service.AutodiscoverUrl("user#domain.com");
Also, you're setting your URL equal to a URi . I don't think that's legal; is it even compiling?
Here is some sample code that I used as a starting point when I implemented something similar - codeproject.com
