I created this little application which calculates an average of temperatures based on values given by user. I am trying to create a news switch statement so that for example the average temperature this week was < 10 it would give a message such as "it was a cold week". Here is my code and what I am doing wrong:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace TempAverages
    public partial class Form1 : Form
        public Form1()

        private void btnCalc_Click(object sender, EventArgs e)
            int tempMonday = Convert.ToInt32(txtMonday.Text);
            int tempTuesday = Convert.ToInt32(txtTuesday.Text);
            int tempWednesday = Convert.ToInt32(txtWednesday.Text);
            int tempThursday = Convert.ToInt32(txtThursday.Text);
            int tempFriday = Convert.ToInt32(txtFriday.Text);
            int weekdays = 5;
            int tempAverage = (tempMonday + tempTuesday + tempWednesday + tempThursday + tempFriday) / weekdays;

            switch (weathernews)

                case 1: tempAverage < 10;
                    lblResult.Text = "it was a cold week with only" + tempAverage;

                case 2: tempAverage > 20;
                    lblResult.Text = "it was quite warm with" + tempAverage;



i get error messages such as "the name weathernews does not exist in the current context"

Indeed, weathernews is nowhere defined in your code. In this case(No pun intended) you are better off with an if elsif statement I guess. Happy programming!

double tempAverage = 8; // just suppose
            string str = string.Empty;
            if (tempAverage < 10)
                str = "it was a cold week with only" + tempAverage;
            else if (tempAverage > 20)
                str = "it was quite warm with" + tempAverage;
            // fill the text of your textbox with str

Something like the above?
