Difference between Class and Structure in c-sharp

Both class and structure are used to define custom data types and encapsulation of data members but some difference between them.

Inheritance: in structure we can not u inherit other structure but in class can inherit other classes.

Reference type vs Value type : Class is reference type means when a object of class is created, a reference of object is created.

changes to the value reflected whenever a reference is used.

Structure is Value type means a object of structure created with value that save in memory and changes to variable not reflected anywhere.

Default Constructor : a class always have default constructor but structure does not have default constructor

Size and Performance : Structure are small in size than classes because they does not have reference variables, that means structure can be faster than classes.

Class Example

public class Author {
 
    // Data members of class
    public string name;
    public string language;
    public int article_no;
 
    // Method of class
    public void Details(string name, string language,
                        int article_no)
    {
        this.name = name;
        this.language = language;
        this.article_no = article_no;        
 
        Console.WriteLine("The name of the author is : " + name
                        + "\nThe name of language is : " + language
                        + "\nTotal number of article published "
                        + article_no + "\nTotal number of Improvements:");
    }
 
    // Main Method
    public static void Main(String[] args)
    {
 
        // Creating object
        Author obj = new Author();
 
        // Calling method of class
        // using class object
        obj.Details("Sachin", "C#", 80, 50);
    }
}

Structure Example

public struct Car
{
    public string Brand;
    public string Model;
    public string Color;
}
 
class GFG {
 
    // Main Method
    static void Main(string[] args)
    {
 
        // Declare c1 of type Car
        // no need to create an
        // instance using 'new' keyword
        Car c1;
 
        // c1's data
        c1.Brand = "Bugatti";
        c1.Model = "Bugatti Veyron EB 16.4";
        c1.Color = "Gray";
 
        // Displaying the values
        Console.WriteLine("Name of brand: " + c1.Brand
                          + "\nModel name: " + c1.Model
                          + "\nColor of car: " + c1.Color);
    }
}
