Question

Need help with develop Visual C# Exercise 4-3 form to display the Fahrenheit temperature and corresponding Celsius temperature for Fahrenheit temperatures ranging from -40 to +40 degrees, at increments of 10. Use a for loop. The conversion formula is Celsius (Fahrenheit - 32) * 5/9. I ran the following but nothing is displaying in my listbox.

I am not familiar with Form1_load, see below. I am not sure how to create in my form. Help please

private void Form1_Load_Click(object sender, EventArgs e)

Answer 1

I have implemented the Code to convert Fahrenheit to Celsius, using VB per the given description.

I HAVE ALSO INCLUDED HOW TO CREATE THE APPLICATION AT THE END.

Please find the following Code Screenshot, Output, and Code.

Click OK.

Then we have :

Form1.vb* Form1.vb [Design]* X다 o Form1 x Server Explorer Toolbox Data Sources

The add a listbox from toolkit.

NOW DOUBLE CLICK INSIDE THE FORM THEN IT WILL OPEN THEN THE GIVEN CODE:
