What is the => assignment in C# in a property signature

Question

I came across some code that said

public int MaxHealth => 
         Memory[Address].IsValid ? 
         Memory[Address].Read(Offs.Life.MaxHp)          


        

Answer 1

It is called Expression Bodied Member and it was introduced in C# 6. It is merely syntactic sugar over a get only property.

It is equivalent to:

public int MaxHealth { get { return Memory[Address].IsValid ?
                             Memory[Address].Read(Offs.Life.MaxHp) : 0; }

An equivalent of a method declaration is avaliable:

public string HelloWorld() => "Hello World";

Mainly allowing you shortening of boilerplate.
