What follows is a description of all the planned language features in C# 7.0. With the release ofVisual Studio “15” Preview 4, most of these features are coming alive. Now is a great time to take them for a spin and tell us your thoughts! C# 7.0 adds a number of new features and...

在C# 7.0 中,通过解构函数完成这项任务将变得轻而易举,解构函数可返回对象的具体确定组件。注意,不要将解构函数 (deconstructor) 与析构函数 (destructor)(确定性对象解除分配和清除)或终结器 (itl.tc/CSharpFinalizers) 混淆。 我们来看看图 1中的 PathInfo 类。
“tuple-like” because, in fact, none of these deconstructor examples actually leverage any tuple type internally. (In fact, assignment of tuples via a deconstructor syntax isn’t allowed and arguably would be somewhat unnecessary because the object assigned already is an instance representing the ...
As I mentioned, each of the preceding examples leveraged the C# 7.0 tuple-like syntax. The syntax is characterized by the parentheses that surround the multiple variables (or properties) that are assigned. I use the term “tuple-like” because, in fact, none of these deconstructor examples act...
