A constructor in C# is called when a class or struct is created. Use constructors to set defaults, limit instantiation, and write flexible, easy-to-read code.

An exception that is thrown as a direct result of a previous exception should include a reference to the previous exception in the InnerException property. The InnerException property returns the same value that is passed into the constructor, or nulla null reference (Nothing in Vis...

移动构造函数(move constructor) 移动分配函数(move assignment) 析构函数(destructor) 因此出于安全考虑,C++11 标准中类的析构函数默认为 noexcept(true)。 但是,如果程序员显式地为析构函数指定了 noexcept(false) 或者类的基类或成员有 noexcept(false) 的析构函数,析构函数就不会再保持默认值。 叶子函数(Leaf...
