What is the { get; set; } Syntax in C# and How Does it Work?

Understanding of { get; set; } syntax in C#

In C#, the { get; set; } syntax is used to define auto-properties. Autoproperties provide a simplified way to define public properties backed by private fields.

Example in ASP.NET MVC

Consider the following code in the ASP.NET MVC model:

<code class="language-csharp">public class Genre
{
    public string Name { get; set; }
}</code>

Explanation

In this example, the { get; set; } syntax means that a private field named "_name" is automatically generated behind the scenes. The "get" section defines getter methods that allow you to access the property's value. The "set" section defines setter methods that allow you to modify the property's value.

Equivalent lengthy code

The following code is equivalent to the automatic attribute syntax:

<code class="language-csharp">private string _name;
public string Name
{
    get
    {
        return this._name;
    }
    set
    {
        this._name = value;
    }
}</code>

Advantages of automatic attributes

Auto attributes have the following advantages:

• Simplicity: They reduce the amount of code required to define properties with getters and setters.
• Encapsulation: They automatically encapsulate private fields, ensuring that external code cannot directly access the field.
• Maintainability: They simplify code changes by centralizing property logic in one place.
