properties - C++/CLI 中的属性是什么？

Question

我看到了 property在 C++ 代码中。我认为它与 C++/CLI 相关。

究竟是什么？

Answer 1

它确实连接到 C++/CLI(非托管 C++ 并没有真正的属性概念)。

Properties are entities that behave like fields but are internally handled by getter and setter accessor functions. They can be scalar properties (where they behave like a field) or indexed properties (where they behave like an array). In the old syntax, we had to specify the getter and setter methods directly in our code to implement properties - wasn't all that well received as you might guess. In C++/CLI, the syntax is more C#-ish and is easier to write and understand.

另见 MSDN关于 C++/CLI 中的属性。

示例代码:

private:
   String^ lastname;

public:
   property String^ LastName
   {
      String^ get()
      {
         // return the value of the private field
         return lastname;
      }
      void set(String^ value)
      {
         // store the value in the private field
         lastname = value;
      }
   }
