Check out example codes for "structure in c sharp with example". It will help you in understanding the concepts better.

Code Example 1

struct Coordinate
{
    public int x;
    public int y;
}

Coordinate point;
Console.Write(point.x); // Compile time error  

point.x = 10;
point.y = 20;
Console.Write(point.x); //output: 10  
Console.Write(point.y); //output: 20

Code Example 2

struct Books {
   public string title;
   public string author;
   public string subject;
   public int book_id;
};

Code Example 3

struct Coordinate
{
    public int x;
    public int y;
}

Coordinate point = new Coordinate();
Console.WriteLine(point.x); //output: 0  
Console.WriteLine(point.y); //output: 0

Code Example 4

struct Coordinate
{
    public int x;
    public int y;
}

Code Example 5

class Program
{
    static void Main(string[] args)
    {

        Coordinate point = new Coordinate();
        
        point.CoordinatesChanged += StructEventHandler;
        point.x = 10;
        point.y = 20;
    }

    static void StructEventHandler(int point)
    {
        Console.WriteLine("Coordinate changed to {0}", point);
    }
}

Code Example 6

Book 1 title : C Programming
Book 1 author : Nuha Ali
Book 1 subject : C Programming Tutorial
Book 1 book_id : 6495407
Book 2 title : Telecom Billing
Book 2 author : Zara Ali
Book 2 subject : Telecom Billing Tutorial
Book 2 book_id : 6495700

Code Example 7

struct Coordinate
{
    public int x { get; set; }
    public int y { get; set; }

    public void SetOrigin()
    {
        this.x = 0;
        this.y = 0;
    }
}

Coordinate point = Coordinate();
point.SetOrigin();

Console.WriteLine(point.x); //output: 0  
Console.WriteLine(point.y); //output: 0

Code Example 8

using System;

   public string title;
   public string author;
   public string subject;
   public int book_id;

      Console.WriteLine("Book 1 author : {0}", Book1.author);
      Console.WriteLine("Book 1 subject : {0}", Book1.subject);
      Console.WriteLine("Book 1 book_id :{0}", Book1.book_id);

      /* print Book2 info */
      Console.WriteLine("Book 2 title : {0}", Book2.title);
      Console.WriteLine("Book 2 author : {0}", Book2.author);
      Console.WriteLine("Book 2 subject : {0}", Book2.subject);
      Console.WriteLine("Book 2 book_id : {0}", Book2.book_id);
