How to put User Input to end the loop on c#

Im new to programming in C# and i encountered some problems, I am trying to create a countdown Console Command but im stuck on how to terminate the loop using a user input (in this case, when the user presses the "Enter" Button)
Here is the code that I currently have
using System;
using System.Threading;
class stopWatch {
public static void Main (string[] args) {
Console.WriteLine ("Access The Clock? Y/N");
string yN = Console.ReadLine();
if ((yN == "y") || (yN == "Y")) {
Console.WriteLine ("Timer (T) or Stopwatch (S)?");
var sT = Console.ReadLine();
if ((sT == "s") || (sT == "S")) {
Console.WriteLine ("Press the 'Enter' Button to Start");
Console.ReadLine();
Console.WriteLine("Stopwatch Started");
Console.WriteLine("Press the 'Enter' Button again to Stop");
for(int i = 0; i >= 0; i ++) {
Console.WriteLine(i);
Thread.Sleep(1000);
}
}
}
else if ((yN =="n") || (yN == "N")) {
Console.WriteLine ("Alright, Thank You");
Environment.Exit(0);
}
else {
Console.WriteLine ("Wrong Input");
Environment.Exit (0);
}
}
}
keep in mind im very new to c# and loops, i'm getting a hard time translating and trying on everything, it'd be really grateful of me to get an extra explanation for your answers

You need to use separate thread for that. Threads is advanced theme, but the basic goal is to do several things at once (in your example run stopwatch and wait for user input). Here is full working code based on your sample:
using System;
using System.Threading;
using System.Threading.Tasks;
namespace ConsoleApp13
{
class Program
{
public static void Main(string[] args)
{
Console.WriteLine("Access The Clock? Y/N");
string yN = Console.ReadLine().ToLower();
if (yN == "y")
{
Console.WriteLine("Timer (T) or Stopwatch (S)?");
var sT = Console.ReadLine().ToLower();
if (sT == "s")
{
Console.WriteLine("Press the 'Enter' Button to Start");
Console.ReadLine();
bool runStopWatch = true;
Task.Run(() =>
{
for (int i = 0;; i++)
{
Console.WriteLine(i);
Thread.Sleep(1000);
if (!runStopWatch)
{
break;
}
}
});
Console.WriteLine("Stopwatch Started");
Console.WriteLine("Press the 'Enter' Button again to Stop");
Console.ReadLine();
runStopWatch = false;
}
}
else if (yN == "n")
{
Console.WriteLine("Alright, Thank You");
Environment.Exit(0);
}
else
{
Console.WriteLine("Wrong Input");
Environment.Exit(0);
}
}
}
}
Task.Run starts a new thread, so your stopwatch runs independent of the main thread (which waits for user to press Enter). Variable runStopWatch is shared between threads (don't think about it right now), so when main thread sets it to false, stopwatch's thread sees it and terminated the loop.
Side mote. More proper way to do this is to use CancellationToken istead of bool variable. But again. don't worry about it right now.

Since you're new im going to try to explain it as simple as possible. The solution you're trying to create is a solution to a multi-threaded problem. This means you will have to do an action while another action takes place. This can be resolved using async methods, this might be too advanced for now, so I will suggest reading up on loops and then multi-threaded programming first.
But for an answer i will have to refer to this post here on how to fix this particular problem. (Look at the second part of the accepted answer).

Ending a loop to return to next sequence

I was trying to make a text adventure in C#. Ive only been coding for a few days and I can't find how to do this.
I was trying to to ask a yes or no question and yes would go to the next question in the story. If its a no I wanted it to start a loop till it forces the player to type the correct answer (yes). After the user types yes how do i get it to exit the loop and move to the next part of the story? If this doesn't make sense ask me and I will try to reexplain.
Here is how i got it to at least go to the next section. I would like it to loop till the user says yes. I would like it to loop though.
using System;
namespace Game.of.words.forgotten.period
{
class Program
{
public static player currentplayer = new player();
static void Main(string[] args)
{
Console.Clear();
Start();
Encounters.Firstencounter();
}
static void Start()
{
Console.WriteLine("Game Of Words The Forgotten Period");
Console.WriteLine("Welcome to my world. What is your name? ");
string currentplayer = Console.ReadLine();
Console.Clear();
Console.WriteLine("We are happy to see you here " + currentplayer + " !");
Console.WriteLine("I bet you are wondering where you are and why you are here. Is that correct? (Yes) or (No)");
string input = Console.ReadLine();
if (input.ToLower() == "yes")
{
//Yes
Console.WriteLine("I thought as much.I am incredibly skilled at the confusion arts");
}
else
{
//no
Console.WriteLine("Well I just assumed because... I mean I took all this time to make this a crazy experience to");
Console.WriteLine(" confuse you but I guess you are too smart for that.");
Console.WriteLine("Please just say yes.");
Console.ReadLine();
if (input.ToLower() == "no")
{
Console.WriteLine("Okay fine. You can be like that");
}
else
Console.Write("I thought as much. I am incredibly skilled at the confusion arts.");
Console.ReadKey();
Console.Clear();
}
Console.ReadLine();
Console.WriteLine("As you see we are in the middle of no where. Surounded by Tall mountains and no trees.");
Console.WriteLine("I bet you can feel the slight breeze and smell the fragrece of the flowers all around us");
Console.WriteLine("Do you want me to telaport us into town or do you walk through the flowers and watch the clouds for a while? ");
Console.ReadLine();
Console.Clear();
}
}
}
Here is another example. I am not understanding something.
class Program
{
static void Main(string[] args)
{
Console.Write("hello Player what is your name? ");
String Name= Console.ReadLine();
string j = ("June");
if (Name != j)
{
Console.WriteLine("Hello " + Name);
while (Name != j)
{
Console.WriteLine("Thats not your name");
// Creates endless loop. If I add a readline it will
//print hello michael and then that is not your name will
//Repeat on every enter.
//If I put a break; it just prints both and ends.
}
Console.ReadLine();
}
Console.ReadLine();
}
}

on the second example you don't really need the if statement, you can use the while loop.
string exitName = "exit";
Console.Write($"hello Player what is your name? (to skip the while loop you must type {exitName}) {Environment.NewLine}");
String Name = Console.ReadLine();
while (Name != exitName)//while the name does not equal 'exit' you will stay in the loop
{
Console.WriteLine("You did not exit!");
Console.WriteLine($"You entered {Name} you must enter {exitName} to exit this loop!");
Name = Console.ReadLine();
}
Console.WriteLine("press any key to end game");
Console.ReadLine();
In your first example you have the lines
Console.WriteLine("Please just say yes.");
Console.ReadLine();
this should be
Console.WriteLine("Please just say yes.");
input = Console.ReadLine();
otherwise you aren't assigning anything to input again.

This do while loop is is going on forever and I can’t get it to stop

I’m trying to make a game where you have to choose a random number, and the computer will tell you if you’re right or not. But in the code I have, the loop will just keep executing what is in the if command. If I try to break it’ll just do what’s in the while part of it. I want to be able to enter a number, tell you if it’s right or not, and then let you guess again. Thanks for the help! Also, ignore how part of the code isn’t counting as code. I couldn’t get it to go into the code part, and I didn’t try very hard either. Also sorry about the abnormal variable names.
using System;
using System.Threading;
namespace newProject
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("useless intro");
int shortOut;
Random rnd = new Random();
int daNumber = rnd.Next(9);
string userNumber = Console.ReadLine();
bool isParsable = Int32.TryParse(userNumber, out shortOut);
if (isParsable)
{
do
{
if (shortOut != daNumber)
{
Console.WriteLine("no");
}
} while (shortOut != daNumber);
Console.WriteLine("that's it yeah");
}
}
}
}

Your code is asking for the user input only once. It then checks if it is an int and, if it is, it then starts the loop that never changes the variables. It's going to loop forever.
You need to ask for the user's input repeatedly until they guess correctly. Asking for the input needs to be in the loop. And you should only break out of the loop when they get it right.
Here's how I would do it:
Random rnd = new Random();
//choose a number between 0 and 8 inclusive
int daNumber = rnd.Next(9);
// start with a value that the user would never enter
int daGuess = int.MinValue;
//loop if the two numbers are not the same
while (daGuess != daNumber)
{
Console.WriteLine("Enter your guess:");
if (int.TryParse(Console.ReadLine(), out daGuess))
{
if (daGuess != daNumber)
{
Console.WriteLine("no");
}
else
{
Console.WriteLine("that's it yeah");
}
}
}

You don't need to check the guess match twice. What you want is an infinite loop that breaks when the condition is true.
int daNumber = new Random().Next(9);
while(true)
{
if (Int32.TryParse(Console.ReadLine(), out int shortOut))
{
if (shortOut == daNumber)
{
Console.WriteLine("that's it yeah");
break;
}
Console.WriteLine("no ");
}
else
{
Console.WriteLine("cannot be parsed as int");
}
}
}

C#, Getting user value and resetting it

Right now my problem is getting choice 2 to save and rewrite what was written in choice 1.
Choice 3 should then reset everything.
Right now i tried with at if inside an if and still not getting it to work.
while (true)
{
Console.WriteLine("\tWelcome to my program"); // Makes the user select a choice
Console.WriteLine("[1] To write");
Console.WriteLine("[2] To see what you wrote");
Console.WriteLine("[3] Reset");
Console.WriteLine("[4] End");
string choice = Console.ReadLine();
string typed = ("");
if (choice == "1") // If 1 program asks for text
{
Console.WriteLine("Thank you for your choice, input text");
typed = Console.ReadLine();
}
else if (choice == "2") // Is supposed to say "You wrote, and what user wrote"
{
Console.WriteLine(typed);
}
else if (choice == "3") // Resets the text so if 2 is selected it would say "You wrote, "
{
Console.WriteLine("Reset. Would you like to try again?");
typed = "";
}
else if (choice == "4") // Ends program
{
break;
}
else
{
Console.WriteLine("Input not computing, try again");
}

Your issue is as follows.
First, you are looping your entire program through a while (true) loop. Once the user choice is made, the program will go back to the while (true). Note also that string typed is defined inside the loop. Therefore, every time the loop is called (which is every choice made), the program resets the value of 'typed'.
To fix this, introduce string typed outside the loop.
string typed = "";
while (true)
{
//choices and stuff goes back here
}
Edit: I noticed this comment of yours //Is supposed to say "You wrote, and what user wrote on choice 2. Note that your code in choice 2 won't output "You wrote" + typed. To correct that, change Console.WriteLine(typed); to Console.WriteLine("You wrote, " + typed);.

Flow of program not what was expected

Building a simple app here; the methods in question:
static coin class
public static void SetUpCoins() {
coin1 = new Coin();
coin2 = new Coin();
}
public static void PlayConsole() {
SetUpCoins();
OutputWinner();
}
public static void OutputWinner() {
if (coin1.ToString() == "Heads" && coin2.ToString() == "Heads") {
Console.WriteLine("You threw Heads - you win");
++point_player;
} else if (coin1.ToString() == "Tails" && coin2.ToString() == "Tails") {
Console.WriteLine("You threw Tails - I win");
++point_comp;
} else {
Console.WriteLine("You threw Odds");
WaitForKey_ConsoleOnly("Press any key to throw again");
PlayConsole();
}
Console.WriteLine("You have {0} points and the computer has {1} points", point_player, point_comp);
if (WantToPlayAgain_ConsoleOnly()) { // ask user if they want to play again; return bool
PlayConsole();
}
}
private static bool WantToPlayAgain_ConsoleOnly() {
string input;
bool validInput = false;
do {
Console.Write("Play Again? (Y or N): ");
input = Console.ReadLine().ToUpper();
validInput = input == "Y" || input == "N";
} while (!validInput);
return input == ("Y");
}
If false was to return from WantToPlayAgain_ConsoleOnly() the program does not exit. Here is an example of the output, which explains my problem:
Why, when WantToPlayAgain_ConsoleOnly is false, does the program not pass control the playConsole method then exit. instead of this repetition.
After OutputWinner is finished running, it then jumps into PlayConsole, and then back into the else statement of the OutputWinner - not sure why.

Because you are calling PlayConsole() after "Press any key to throw again". Once that call returns the program will unconditionally continue with "You have {0} points and the computer has {1} points", regardless of what happened during the call.
Try rewriting the logic to be iterative rather than recursive?

As the previous answers said, you have a problem when you throw odds.
Because at that point you call the exact same method again and when that call returns, you resume right at the score display and the player is asked again to play.
Because you are calling PlayConsole recursively, that means for every time you throw "Odd", you will get one more prompt that you didn't ask for.
You could restructure the method like this:
public static void OutputWinner() {
do {
// Game code
}
while (WantToPlayAgain_ConsoleOnly());
}
That also gets rid of the recursion.
