Question

I am working with random and sorting methods. So far I have the linear method working. I am trying to implement a way that will let the user decide which type of sorting to use such as linear, bubble, index, etc. So I have added textBox7 with the label Key and button3 which the user clicks until the find their desired sorting method. When Keytextbox7 has a value chosen then the sort array button2 will execute that particular sorting method. How can I execute a particular sorting method based on the Key value? Below is picture of how I have the windows form set up

CODE

namespace sortmachine
{
    public partial class Form1 : Form
    {

        public Form1()
        {
            InitializeComponent();

        }


        Stopwatch sw = new Stopwatch();


        Random r = new Random();

        private int size = 0;
        private int max = 0;
        private int ops = 0;
        private int[] ar1;
        private int[] ar2;
        private int[] ar3;

        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                size = Convert.ToInt32(textBox2.Text);
                max = Convert.ToInt32(textBox3.Text);
                string s = "";

                ar1 = new int[size];
                ar2 = new int[size];
                ar3 = new int[size];

                for (int i = 0; i < size; i++)
                {
                    int n = r.Next(0, max);
                    ar1[i] = n;
                    ar2[i] = ar1[i];
                }

                for (int i = 0; i < size; i++)
                {
                    s += ar1[i].ToString() + " ";
                }
                listView1.Items.Add(s);
            }
            catch
            {
                MessageBox.Show("Please input information");
            }

        }

        private void button2_Click(object sender, EventArgs e)
        {
            int min = max;
            int n = 0;
            string s="";

            sw.Start();

            for (int j = 0; j < size; j++)
            {
                for (int i = 0; i < size; i++)
                {
                    if (min > ar2[i])
                    {
                        min = ar2[i];
                        n = i;
                        ops++;
                    }
                    if (min < ar2[i])
                    {
                        ops++;
                    }

                }
                ar2[n]=max;
                ar3[j] = min;
                min = max;
                s += ar3[j] + " ";
            }

            TimeSpan x = sw.Elapsed;
            textBox5.Text = x.ToString();

                listView2.Items.Add(s);
                listView2.Text = s;
                textBox6.Text = Convert.ToString(ops);
                if (checkBox1.Checked==true)
                {
                    textBox1.AppendText(s+Environment.NewLine);
                }
                for (int i = 0; i < size; i++)
                {
                    ar2[i] = ar1[i];
                }
                ops = 0;

        }

    }
}

Answer 1

Id give this a go as it implements what others were suggesting:

Inside each if conditional you can perform your own logic per sort type. As you can see I have a sorting option selected from the combobox with other buttons to add numbers to my list for sorting and a control to display the results.

The code is as follows in the Screenshot:

if(comboBox1.SelectedItem.ToString() == "Linear")
{
}
else if (comboBox1.SelectedItem.ToString() == "Bubble")
{            
}
else if (comboBox1.SelectedItem.ToString() == "Index")
{
}
