Fraction struct

<source lang="csharp">using System; public struct Fraction {

   public Fraction(double _divisor, double _dividend) {
       divisor = _divisor;
       dividend = _dividend;
   }
   public double quotient {
       get {
           return divisor / dividend;
       }
   }
   private double divisor;
   private double dividend;

} public class Calculate {

   public static void Main() {
       Fraction number = new Fraction(4, 5);
       Console.WriteLine("{0}", number.quotient);
   }

}</source>

Struct constructor with parameters

<source lang="csharp">using System; struct Point {

  public int x;
  public int y;
  public Point(int a, int b) 
  {
     x = a;
     y = b;
  }

} class MainClass {

  static void Main()
  {
     Point p1 = new Point();
     Point p2 = new Point(5, 10);
     Console.WriteLine("{0},{1}", p1.x, p1.y);
     Console.WriteLine("{0},{1}", p2.x, p2.y);
  }

}</source>

Structs with constructors

<source lang="csharp">using System; struct Point {

   int x;
   int y;
   
   Point(int x, int y)
   {
       this.x = x;
       this.y = y;
   }
   public override string ToString()
   {
       return(String.Format("({0}, {1})", x, y));
   }

} class MainClass {

   public static void Main()
   {
       Point[] points = new Point[5];
       Console.WriteLine("[2] = {0}", points[2]);
   }

}</source>

[2] = (0, 0)

Use method to init struct member variables

<source lang="csharp">using System;

public struct Simple {

 public  int i;
 private string s;
 
 public void init( ) {
   i = 10;
   s = "Hello";
 }
 

}

public class MainClass {

 public static void Main( ) {
   Simple simple = new Simple();
 
   simple.init( );
   
 }

}</source>
