However, it can be declared in private scope, as well. For instance, consider a class called Car with make, model, and year as its data members. We can create a constructor for the Car class that takes arguments for each of these data members and initializes them when a Car object is...

Learn how and when to declare primary constructors in your class and struct types. Primary constructors provide concise syntax to declare constructor parameters available anywhere in your type.
A constructor declared without thefunction-specifierexplicitspecifies a conversion from the types of its parameters to the type of its class. Such a constructor is called a converting constructor. 这个语法本身起始没有什么经验的地方,而且从这个语法定义来看,这个语法适用的范围很小,几乎没有什么应用场景。
When astructis set to itsdefaultvalue, the runtime initializes all memory in the struct to 0. If you declare any field initializers in astructtype, you must supply a parameterless constructor. For more information, see theStruct initialization and default valuessection of theStructure typesarticle...
