Lambda for getter and setter of property

Question

In C# 6.0 I can write:

public int Prop => 777;

But I want to use getter and setter. Is there a way to do something kind of the next?

Answer 1

C# 7 brings support for setters, amongst other members:

More expression bodied members

Expression bodied methods, properties etc. are a big hit in C# 6.0, but we didn’t allow them in all kinds of members. C# 7.0 adds accessors, constructors and finalizers to the list of things that can have expression bodies:

class Person
{
    private static ConcurrentDictionary names = new ConcurrentDictionary();
    private int id = GetId();

    public Person(string name) => names.TryAdd(id, name); // constructors
    ~Person() => names.TryRemove(id, out _);              // finalizers
    public string Name
    {
        get => names[id];                                 // getters
        set => names[id] = value;                         // setters
    }
}
