C# by Example: Expression-Bodied Properties


using Systems.Collections.Generic;
using System.Linq;
public class ExpressionBodiedExample
{

Expression-Bodied properties let you define an implementation in a consise way. They serve as an alternative syntax for getters and reduce the need to write one-line functions.


    public string member => expression;


    private List<string> _names;

They are often used for convenience and simplicity.


    public int Count => _names.Count;
    public bool AnyNames => _names != null && _names.Count > 0;

In Unity, one could apply attributes to a private member, like [SerializeField], and use an expression-bodied property for a public getter.


    public List<string> Names => _names;

Expreession-bodied members work well with LINQ expressions, which can often accomplish a lot of functionality in a single line.


    public int Franks => _names.Where(x => x == "Frank").Count();
    public List<string> GetNamesCapitalized() => _names.Select(n => Char.ToUpperInvariant(n[0]) + n.Substring(1).ToLower()).ToList();
    
}
