转换运算子和建构函式已经定义为产生相同的转换。
A conversion operator and a constructor have been defined making the same conversion.
例如，属性无法在建构函式的初始化清单中初始化。
A property cannot be initialized, for example, in a constructor's initialization list.
或是可以在所有建构函式呼叫的初始设定方法中宣告。
Or you could declare it in an initialization method that is called by all constructors.
读取伫列时，最常用的是具有目标型别参数的建构函式。
The constructors with target type parameters are most frequently used when reading from the queue.
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.
平台叫用无法用于依照值传回包含建构函式的结构或类别。
Platform invoke cannot be used to return structures or classes by value if they contain a constructor.
当您想要传递错误讯息给使用者时，可以使用此建构函式。
Use this constructor when you want to pass an error message to the user.
取得或设定值，指出型别参数是否具有建构函式条件约束。
Gets or sets a value indicating whether the type parameter has a constructor constraint.
描述动态类别之建构函式的定义、所用的属性，以及其限制。
Describes the definition of constructors for dynamic classes, the attributes used, and limitations.
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.
执行个体建构函式也可以用来呼叫基底类别的执行个体建构函式。
Instance constructors can also be used to call the instance constructors of base classes.
这可用来建立完整的功能表结构，并指派到功能表项目的建构函式。
This enables you to create complete menu structures and assign them to the constructor for the menu item.
在这种情况下，应用程序可以使用其中一个接受识别项值的建构函式。
