属性：Get Accessor 与 Expression-Bodied 成员

Question

这些似乎实际上是等价的：

bool PropertyAsExpressionBody => true;
bool PropertyAsGetAccessor {
    get {
        return true; // or just { get => true; }
    }
}

声明一个 get 访问器（假设你没有 want/need 一个 setter）和一个表达式体属性之间有什么功能上的区别吗？

Answer 1

他们是同一张照片..东西.

见here:

Starting with C# 6, read-only properties can implement the get accessor as an expression-bodied member. In this case, neither the get accessor keyword nor the return keyword is used.

和here:

Starting with C# 7.0, you can use expression body definitions to implement property get and set accessors.
