I need my Visual Basic code translated to C# code.

Here is the VB code:

Name of AddOn Group = GroupBox1

Name of place order button = btn_place_order

Public Class Form1

''Set addons text on form load

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

GroupBox1.Text = "Add-on Item($.75 each)"

CheckBox1.Text = "Lettuce,Tomato and onion"

CheckBox2.Text = "Ketchup,mustered and Mayo "

CheckBox3.Text = "French Fries"

End Sub

'' method to clear addons

Sub clearAddOns()

CheckBox1.Checked = False

CheckBox2.Checked = False

CheckBox3.Checked = False

End Sub

''Method to clear Order total group

Sub clearTotals()

TextBox1.Text = ""

TextBox2.Text = ""

TextBox3.Text = ""

End Sub

'' Radio Button 1 check event handler (hamburger)

Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged

GroupBox1.Text = "Add-on Item($.75 each)"

CheckBox1.Text = "Lettuce,Tomato and onion"

CheckBox2.Text = "Ketchup,mustered and Mayo "

CheckBox3.Text = "French Fries"

'' clears addons on change of main course

clearAddOns()

End Sub

'' Radio Button 2 check event handler (Pizza)

GroupBox1.Text = "Add-on Item($.50 each)"

CheckBox1.Text = "Peperoni"

CheckBox2.Text = "Sauces "

CheckBox3.Text = "Olives"

'' clears addons on change of main course

clearAddOns()

End Sub

'' Radio Button 3 check event handler (Salad)

CheckBox1.Text = "Croutons"

CheckBox2.Text = "Bacon bits"

CheckBox3.Text = "Bread sticks"

'' clears addons on change of main course

clearAddOns()

End Sub

'' Button Place order click event handler

Private Sub btn_place_order_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_place_order.Click

'' variable declaration

Dim addon As Double

Dim mainc As Double

Dim subtotal As Double

Dim total As Double

'' if 1st add on added, add its price

End If

'' if 2nd add on added, add its price

If CheckBox2.Checked = True Then

subtotal = subtotal + addon

End If

'' if 3rd add on added, add its price

If CheckBox3.Checked = True Then

subtotal = subtotal + addon

End If

'' calculate tax

'' calculate total

total = tax + subtotal

'' display subtotal, tax and Order total in textbox as string with 2 decimal place format

TextBox1.Text = subtotal.ToString

TextBox2.Text = tax.ToString("#.##")

TextBox3.Text = total.ToString("#.##")

End Sub

'' clears total on change of check box (true or false)

The requiremetns for the project is shown below:

C-Sharp University needs you to create a form that accepts a lunch order from the student and then calculates the order subtotal and total. Lunch Order Main course Addon ters ($ 75each) Hamburger-$6 3 5Leftuce, tomato and anion Ketchup, mutard, and mayo Salad-$495 French fhes Order total Subtotal: Order tota The application should provide for these main courses and add-ons: Main course Add-on price 75 695 Lettuce, tomato, and onion Ketchup, mustand, and mayo French fries Pizza 5.95 50 Sausage Olives Salad 4.95 25 Croutons Bacon bits Bread sticks Add three radio buttons to the Main Course group box, and set their properties so they appear as shown above. The Hamburger option should be selected by default. Add a group box for the add-on items. Then, add three check boxes to this group box as shown above. None of the check boxes should be selected by default. Code a method name ClearTotals that clears the three text boxes and a method named ClearAddOns that removes the check marks from the three check boxes Code an event handler (this will reference the three radio button checked changed event listed on the form) that changes the text that's displayed for the Add-ons group box and the three check boxes when the user selects a different main course
