如何使用此C＃代碼創建默認構造函數？

Question

我想使用這段代碼創建一個默認構造函數。這是一個沒有構造函數原來，有人可以請幫助？：

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 Chapter_2_Test 
{ 
public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 
    } 



    private void Order_Click(object sender, EventArgs e) 
    { 

    string cakeFlavor, frostingFlavor; 
    int size; //This declasres an integer that represents size 
    cakeFlavor = Cake.Text;   frostingFlavor = Frosting.Text; 
    size = Convert.ToInt32(Size.Text); 

    Display.Text = "Cake Flavor: " + cakeFlavor + Environment.NewLine + "Frosting Flavor: " + frostingFlavor + Environment.NewLine + "Cake Size: " + size + " Inches" + Environment.NewLine + "Thank you for shopping" + enter code hereEnvironment.NewLine + "at The Token Bakery!"; 
     //This Displays all the info that the user input 

    } 

} 

}

這將不勝感激。謝謝！

public string CakeFlavor

    set { _frostingFlavor = value; }

#endregion 

#region Constructors 
public Cake() : this("Cake flavor not provided.", "Frosting flavor not provided.")

    this._frostingFlavor = frostingFlavor; 
} 
#endregion 

#region Methods 
public void PrintCakeFlavors()

    Console.WriteLine("Cake Flavor: {0}\nFrosting Flavor: {1}", this._cakeFlavor, this._frostingFlavor);
