How can i use the list in one function which has some data added in another function

So here is my first file QuizzyService:
List<Question> newQuestions = new List<Question>();
public static List<Question> QuizzyServiceQuestions()
{
using (Stream stream = File.Open("..\\Debug\\questions.bin", FileMode.Open))
{
var binaryFormatter = new BinaryFormatter();
return (List<Question>)binaryFormatter.Deserialize(stream);
}
}
int curQuestion = 0;
public Question NewGame(int questionCount)
{
Random r = new Random();
for(int i = 0; i < questionCount; i++)
{
Question x = QuizzyServiceQuestions()[r.Next(0, QuizzyServiceQuestions().Count)];
while (newQuestions.Contains(x))
{
x = QuizzyServiceQuestions()[r.Next(0, QuizzyServiceQuestions().Count)];
}
newQuestions.Add(x);
}
Console.WriteLine(newQuestions.Count);
return newQuestions[0];
}
public int CheckAnswer(int questionId, int answerId)
{
List<int> IdList = new List<int>();
for (int i = 0; i < QuizzyServiceQuestions().Count; i++)
{
IdList.Add(QuizzyServiceQuestions()[i].Id);
}
return IdList.Single(i => i == questionId);
}
public Question GetNextQuestion()
{
curQuestion += 1;
Console.WriteLine(newQuestions.Count);
//Console.WriteLine(curQuestion);
//Console.WriteLine(this.newQuestions.Count);
return newQuestions[curQuestion];
}
Here the relevant part of the xaml.cs file:
private int totalQuestionCount;
private int currentQuestionCount = 1;
private int correctAnswerCount;
Question newQuestion = new Question();
public MainWindow()
{
InitializeComponent();
}
private void btnNewGame_Click(object sender, RoutedEventArgs e)
{
if (!int.TryParse(tbQuestionCount.Text.Trim(), out totalQuestionCount))
{
tblStatus.Text = "Invalid question count!";
return;
}
correctAnswerCount = 0;
tblStatus.Text = string.Empty;
using(WpfQuizzyClient.QuizzyRef.QuizzyServiceClient client = new WpfQuizzyClient.QuizzyRef.QuizzyServiceClient("WSHttpBinding_IQuizzyService"))
{
newQuestion = client.NewGame(Convert.ToInt32(totalQuestionCount));
UpdateUserInterface(newQuestion);
}
}
private void btnAnswer_Click(object sender, RoutedEventArgs e)
{
Button button = (Button)sender;
int answerId = -1;
switch (button.Name)
{
case "btnAnswerA": answerId = 0; break;
case "btnAnswerB": answerId = 1; break;
case "btnAnswerC": answerId = 2; break;
case "btnAnswerD": answerId = 3; break;
default:
// This should never happen
MessageBox.Show("Invalid button name detected - contact support!");
return;
}
using (WpfQuizzyClient.QuizzyRef.QuizzyServiceClient client = new WpfQuizzyClient.QuizzyRef.QuizzyServiceClient("WSHttpBinding_IQuizzyService"))
{
if (answerId == client.CheckAnswer(newQuestion.Id, answerId))
{
tblStatus.Text = string.Empty;
tblStatus.Text = "Correct! Total: " + currentQuestionCount + " / " + totalQuestionCount;
currentQuestionCount += 1;
UpdateUserInterface(client.GetNextQuestion());
}
else
{
tblStatus.Text = string.Empty;
UpdateUserInterface(client.GetNextQuestion());
}
}
My problem is that when i trigger btnAnswer_Click it doesnt have the list which has been created in NewGame but im not allowed to do something like NextQuestion(Question questionList)
If you need more info just tell me and i'll make sure to provide more as quickly as possible!

i found the fix ... i just had to remove both using and add the "WpfQuizzyClient.QuizzyRef.QuizzyServiceClient client = new WpfQuizzyClient.QuizzyRef.QuizzyServiceClient("WSHttpBinding_IQuizzyService")" before the MainWindow()

Parallel compression folder, best solution in c#

I need to compress more folder at same time in different archivie to goes more quikly.
I tried to use a main backgroundworker and from this I did a for cycle to start other backgroundworker for each folder. I notice that the backgroundworker starts all at same time but not works together what is the best way to do a parallel archive?what you suggest?
to create the archive I use the zipforge library
DoWork of the main backgroundworker

Stopping the calculations because of predicted error

I am unsure how to ask this question as I can't quite well translate it.
I am currently working on my own Windows Form Application that will calculate the dimensions of a given package in inches (written all together in string format) and calculate the dimensions in centimeters, milimeters or even meters and at this point I was wondering what if someone entered wrong dimensions and given measures can not be parsed.
Something like Environment.Exit(), but without closing the application just stopping calculations and writing a message that an error has occured.
If there is a question like this answered, please do link it because I haven't been able to find it.

It should be pretty simple, depending on your requirements. For example, you could just use a basic if block in your method.
void CalculateStuff()
{
// Get input. Do stuff.
if (IsInvalid)
{
MessageBox.Show("You did a bad thing.");
return; // exit the method.
}
// now that we know the input is good, do other stuff.
}
Substitute IsInvalid with whatever check condition you want that will return true if the input is not valid.

C# Make an autocomplete to a RichTextBox

I have a list of numberes, and I want to make a RichTextBox with autocomplete, so when the user start typing a number, it will give him autocomplete options from the list.
And I want it to be in a RichTextBox because I want the user to be able writing each number in a new line in the RichTextBox, so everytime the user presses enter, it will do the whole autocomplete thing all over again.
I don't really have an idea how to et this ting done.
any help would be very thankfull.
Thanks

I'll paste the code here. I never got the positioning of the box correct, so you will have to play around with the YOffset and the XOffset.
In your form OnLoad:
intellisenseRichTextBox.IntellisenseWords = new string[] { "Test", "Foo", "Bar", "Supercalifragilisticexpialidocious" };
intellisenseRichTextBox.YOffset = 132;
intellisenseRichTextBox.XOffset = 70;
And the classes:

Add text to list when user presses button in Android app?
