What is the {get; set;} Syntax in C# and How Does it Create Auto-Properties?

In-depth understanding of {get; set;} syntax in C#

In ASP.NET MVC development, you may encounter the {get; set;} syntax in C# code, which may be confusing for beginners. This syntax is used to create automatic properties, which is a simplified way to define properties that do not require custom getter and setter methods.

Auto attribute syntax: {get; set;}

{get; set;} syntax consists of two parts:

• get: Defines the getter method that returns the attribute value.
• set: Defines the setter method for setting attribute values.

Let’s look at an example:

public class Genre
{
    public string Name { get; set; }
}

This code creates an automatic property of type string named "Name". It also defines the getter and setter methods of the property:

• Getter: is equivalent to public string Name { get { return this.name; } }
• Setter: is equivalent to public string Name { set { this.name = value; } }

Abbreviations for custom getters and setters

Auto properties are actually shorthand for the following code, which manually defines getters and setters:

private string name;

public string Name
{
    get
    {
        return this.name;
    }

    set
    {
        this.name = value;
    }
}

By using automatic properties, you can create properties with minimal code duplication and boilerplate code. They are particularly useful for simple properties that follow standard getter and setter behavior.
