Temperature Conversion Visual Programming C Sharp

Temperature Conversion Visual Programming C Sharp – Design a Windows Forms Application in visual studio using C Sharp. Add a label for program header in a label control. Use a text box to input temperature to be converted. When we click on any one of the radio buttons with option To Celsius or To Fahrenheit, one option is selected. Click on Convert button to display converted temperature.

Explanation of the Temperature Conversion Program in C Sharp

1. The program is defined in the TemperatureConversion namespace and contains a partial class named Form1, which represents the main form of the application.
2. The Form1 constructor (public Form1()) initializes the components of the form. This constructor is responsible for setting up the GUI components and their initial properties.
3. The button1_Click method is an event handler that executes when the button labeled “button1” (likely named by default) is clicked.
4. Inside the button1_Click method:
   • The method starts by declaring two variables, f for Fahrenheit and c for Celsius.
   • It checks which radio button is selected (Fahrenheit to Celsius or Celsius to Fahrenheit).
   • If the “Fahrenheit to Celsius” radio button (radioButton1) is checked, the Fahrenheit value is parsed from the text in textBox1, and the Celsius value is calculated and displayed using the conversion formula. The calculated Celsius value is shown in a message box.
   • If the “Celsius to Fahrenheit” radio button (radioButton2) is checked, the Celsius value is parsed from textBox1, and the Fahrenheit value is calculated and displayed using the conversion formula. The calculated Fahrenheit value is shown in a message box.
5. The conversion formulas for Fahrenheit to Celsius and Celsius to Fahrenheit are applied accordingly:
   • Fahrenheit to Celsius: (Fahrenheit - 32) * 5 / 9
   • Celsius to Fahrenheit: (Celsius * 9 / 5) + 32

This program allows the user to input a temperature value in one unit (Fahrenheit or Celsius), choose the target unit for conversion, and then displays the converted temperature value in the other unit using a message box. It demonstrates a basic usage of Windows Forms and event handling in C#.
