C# Tip: Expression-bodied Members

Let’s talk about Expression-bodied Members, introduced in C# 6, which allow simplifying the syntax of methods, properties, and other members that return a value. See the example in the code below.

public class Product

{

    public string Name { get; set; }

    public decimal Price { get; set; }



    // Using Expression-bodied Member for the ToString method

    public override string ToString() => $"Product: {Name}, Price: {Price:C}";

}



public class Program

{

    public static void Main()

    {

        var product = new Product { Name = "Pen", Price = 2.99m };

        Console.WriteLine(product);

    }

}

Explanation:

With Expression-bodied Members, you can define methods, properties, and operators more concisely, using the => syntax instead of full code blocks. This is especially useful for members that consist of a single line of code, making the code cleaner and easier to read. In the example above, we show how to simplify the definition of a ToString method using this syntax.
