Question

I’m making a hangman game, this part of the code goes behind the button new game. Everytime the user selects new game I want the game to load a new word for users to guess. My problem is I need to put my code in to a loop. For example if non of the if/else statements are not true, select another random number until a statement is true…

I hope that make sense =) Here’s my code so far.

namespace HangMan
{
public partial class Form1 : Form
{
    int RW;
    string previous;

    public Form1()
    {
        InitializeComponent();

    }



    private void Form1_Load(object sender, EventArgs e)
    {
        foreach (TextBox textBox in addTextBox())
        {
            textBox.Visible = false;
            textBox.Text = "";
        }
    }

    private static void LoadImages()
    {
        Image newImageIntro = Image.FromFile("HangmanIntro.jpg");
        Image newImage1 = Image.FromFile("1.jpg");
        Image newImage2 = Image.FromFile("2.jpg");
        Image newImage3 = Image.FromFile("3.jpg");
        Image newImage4 = Image.FromFile("4.jpg");
        Image newImage5 = Image.FromFile("5.jpg");
        Image newImage6 = Image.FromFile("6.jpg");
        Image newImage7 = Image.FromFile("7.jpg");
        Image newImage8 = Image.FromFile("8.jpg");
        Image newImage9 = Image.FromFile("9.jpg");
    }

    private void txtEnText_TextChanged(object sender, EventArgs e)
    {

    }

    private void txtEnText_Enter(object sender, EventArgs e)
    {

    }

public List<TextBox> addTextBox()
    {
        List<TextBox> tBox = new List<TextBox>();

        tBox.Add(textBox1);
        tBox.Add(textBox2);
        tBox.Add(textBox3);
        tBox.Add(textBox4);
        tBox.Add(textBox5);
        tBox.Add(textBox6);
        tBox.Add(textBox7);
        tBox.Add(textBox8);
        tBox.Add(textBox9);
        tBox.Add(textBox10);

        return tBox;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Random rW = new Random();

        foreach (TextBox textBox in addTextBox())
        {
            textBox.Visible = false;
        }


        RW = rW.Next(1, 4);

        if (RW == 1 & previous != "1" ) //Cat
        {
            textBox1.Visible = true;
            textBox2.Visible = true;
            textBox3.Visible = true;
            previous = "1";


        }
        else if (RW == 2 & previous != "2" ) //Elephant
        {
            textBox1.Visible = true;
            textBox2.Visible = true;
            textBox3.Visible = true;
            textBox4.Visible = true;
            textBox5.Visible = true;
            textBox6.Visible = true;
            textBox7.Visible = true;
            textBox8.Visible = true;
            previous = "2";
        }
        else if (RW == 3 & previous != "3") //Giraffe
        {
            textBox1.Visible = true;
            textBox2.Visible = true;
            textBox3.Visible = true;
            textBox4.Visible = true;
            textBox5.Visible = true;
            textBox6.Visible = true;
            textBox7.Visible = true;
            previous = "3";
        }
        else if (RW == 4 & previous != "4") //Monkey
        {
            textBox1.Visible = true;
            textBox2.Visible = true;
            textBox3.Visible = true;
            textBox4.Visible = true;
            textBox5.Visible = true;
            textBox6.Visible = true;
            previous = "4";
        }
        else
        {
        }



    }
}

Answer 1

Put this around your code:

while(true)
{
// CODE
break;
}

and inside the else {} part:

continue;

Edit:
You can also use LINQ, e. g.

while(Controls.OfType<TextBox>().All(t => !t.Visible))

if you only have those boxes whose visibility changes inside the loop.
