当您使用物件初始设定式来建立具名型别的执行个体时，会呼叫类别的预设建构函式，接著按照您指定的顺序初始化指定的成员。
When you use an object initializer to create an instance of a named type, the default constructor for the class is called, followed by initialization of designated members in the order you specify.
当阵列在建构函式的成员初始设定清单中时，阵列元素将预设为初始化。
When an array is in a constructor's member initialization list, the elements of the array will be default initialized.
如果类别没有任何的建构函式，则会自动产生预设建构函式，而预设值会用于初始化栏位。
If a class does not have a constructor, a default constructor is automatically generated and default values are used to initialize the object fields.
空的建构函式宣告防止自动产生预设建构函式。
The declaration of the empty constructor prevents the automatic generation of a default constructor.
该型别针对其值不一定支援属性语法，也不一定支援物件项目语法(需要该型别上的预设建构函式)。
That type may or may not support attribute syntax for its values, or may or may not support object element syntax (which requires a default constructor on that type).
否则，新项目也可以透过其公用预设建构函式自动建立。
Otherwise, the new item is automatically created through its public default constructor.
如果您为动态型别定义了建构函式，则不会提供预设建构函式。
If you define a constructor for your dynamic type, a default constructor is not provided.
如果您没有为动态型别定义建构函式，便会自动提供一个预设的建构函式，而且它会呼叫基底类别的预设建构函式。
If you do not define a constructor for your dynamic type, a default constructor is provided automatically, and it calls the default constructor of the base class.
如果您没有为动态型别定义建构函式，便会自动提供一个预设的建构函式，而且它会呼叫基底类别的预设建构函式。
If you do not define a constructor for your dynamic type, a default constructor is provided automatically, and it calls the default constructor of the base class.
