DialogResult Infinite Loop - while-loop

Question

So I have this project at school to create a game "Guess the number". I am trying to loop a DialogResult using a switch statement and a while loop. I tried many possibilities but I go into a infinite loop. Just to know I am a beginner.I would really need some help here if possible. This is my code. Thanks in advance.
private void btnStartTheGame_Click(object sender, EventArgs e)
{
int guessTheNumber = Convert.ToInt32(txtNumberGuess.Text);
DialogResult dialogResult = MessageBox.Show("Is number" + number.ToString() + " you are thinking about?", "Answer the question!", MessageBoxButtons.YesNo);
switch(dialogResult)
{
case DialogResult.No:
while (dialogResult == DialogResult.No)
{
Random newNumberGenerator = new Random();
number = newNumberGenerator.Next(0, 101);
MessageBox.Show("Is number" + number.ToString() + " you are thinking about?", "Answer the question!", MessageBoxButtons.YesNo);
}
break;
case DialogResult.Yes:
if (dialogResult == DialogResult.Yes)
{
MessageBox.Show("Congratulation! You guessed the number!!");
break;
}
break;
}

Answer 1

You need to load the new result of the dialog.
int guessTheNumber = Convert.ToInt32(txtNumberGuess.Text);
DialogResult dialogResult;
do
{
Random newNumberGenerator = new Random();
number = newNumberGenerator.Next(0, 101);
dialogResult = MessageBox.Show("Is number" + number.ToString() + " you are thinking about?", "Answer the question!", MessageBoxButtons.YesNo);
} while (dialogResult == DialogResult.No);
MessageBox.Show("Congratulation! You guessed the number!!");
The do loop will execute the code first, and then check the condition. THis will also prevent having the same piece of code at different places, meaning the same.
