Structure (C#)

Structure is the value type data type that can contain variables, methods, properties, events and so on. It simplifies the program and enhance performance of code in C# programming.

The structure encapsulate small group of related variables inside a single user-defined data type. It improves speed and memory usage and also enhances performance and clarity of your code.

How to use structure in C#?

It is very simple to use structure in C#. The following programming example will show you to how to create and use structure in C# programming.


Programming Example of Structure (C#)
using System;

namespace Structure
{
  class Program
   {
     // creating three different variable in single structure
     struct book
      {
        public string bookname;
        public int price;
        public string category;
      }

     static void Main(string[] args)
      {
        //Creating two book type variable
        book language, database;

        // Storing value in language variable
        Console.Write("Enter book name:\t");
        language.bookname = Console.ReadLine();
        Console.Write("Enter book price:\t");
        language.price = Convert.ToInt32(Console.ReadLine());
        Console.Write("Enter book category:\t");
        language.category = Console.ReadLine();

        //Storing value in database variable
        Console.Write("\n\nEnter book name:\t");
        database.bookname = Console.ReadLine();
        Console.Write("Enter book price:\t");
        database.price = Convert.ToInt32(Console.ReadLine());
        Console.Write("Enter book category:\t");
        database.category = Console.ReadLine();


        //Displaying value of language variable
        Console.Write("\n\n===================");
        Console.Write("\n\t\tLanguage\n");
        Console.Write("===================\n\n");

        Console.Write("Book Name:\t{0}",language.bookname);
        Console.Write("\nBook Price:\t{0}",language.price);
        Console.Write("\nBook Category:\t{0}",language.category);

        Console.Write("\n\n==================\n");
        Console.Write("\t\tDatabase\n");
        Console.Write("====================\n\n");

        Console.Write("Book Name:\t{0}",database.bookname);
        Console.Write("\nBook Price:\t{0}",database.price);
        Console.Write("\nBook Category:\t{0}",database.category);

        Console.ReadLine();          
      }
   }
}



Output
Enter book name :         C Sharp
Enter book price :         34
Enter book category :    Object Oriented Programming


Enter book name :         SQL Server
Enter book price :         23
Enter book category :    Database Programming


=============================================
         Language
=============================================

Enter book name :         C Sharp
Enter book price :         34
Enter book category :    Object Oriented Programming


=============================================
         Database
=============================================

Enter book name :         SQL Server
Enter book price :         23
Enter book category :    Database Programming


In the preceding example, we create a structure named book that contain three variables as bookname, price, category. These variables can be accessed by creating the object of book structure.
Next, we create two variables of book as language and database. Then store the value in language and database and display the value on console.

Write a program to enter a number from 1 to 7 and display the corresponding day of the week. Hint: 1 = Monday ..

using System; class sevenday { public static void Main() { int num1; Console.WriteLine("Enter Number From 1 - 7 to find the correponding day"); num1=Convert.ToInt32(Console.ReadLine()); switch(num1) { case 1: Console.WriteLine(" 1 is Monday"); break; case 2: Console.WriteLine("2 is tuesday"); break; case 3: Console.WriteLine("3 is wednesday"); break; case 4: Console.WriteLine("4 is Thrusday"); break; case 5: Console.WriteLine("5 is friday"); break; case 6: Console.WriteLine("6 is saturday"); break; case 7: Console.WriteLine("7 is sunday"); break; default: Console.WriteLine(" Your Number is Invalid Please Enter Correct Number"); break; } } }

C# Statements

There are various basic things in C# that you need to know. These are very small but too effective. These are called statements in C#. Without covering statements in C#, you can’t be a good programmer. In C# programming, there is various statements as block, empty, goto-label, break, continue, return, throw, checked, unchecked, lock, using etc. These are small but give powerful control you to write your program. List of Contents C# Statements Chapter 1: Block Chapter 2: Empty Chapter 3: Goto-label Chapter 4: Break Chapter 5: Continue Chapter 6: Return Chapter 7: Throw Chapter 8: Checked Chapter 9: Unchecked Chapter 10: Lock Chapter 11: Using Chapter 12: Enumeration Chapter 13: Structure Chapter 14: Examples

C# Enumeration

Enumeration provides efficient way to assign multiple constant integral values to a single variable. Enumeration improves code clarity and makes program easier to maintain. Enumeration in C# also provides more security by better error-checking technology and compiler warnings. An enumeration can be defined using enum keyword. In enumeration, you can define special set of value that can be assigned with enumeration. For Example, you are creating an attendance log application in which a variable can contains value only Monday to Friday. The other value will not be applicable with variables. In order to fulfill this requirement you need to use enumeration that will hold only assigned values and will returns numeric position of values starting with zero. Programming Example of Enumeration (C#) using System; namespace Enumeration {    // creating enumeration for storing day.    public enum attandance    {       ...
