抽象密封&文字 [英] abstract sealed & literal

问题描述

ref struct XXX abstract sealed

{

literal int A = 5;

};


上面的定义给了我编译器警告C4693：一个密封的摘要

类不能有任何实例成员''A''。相同的定义是

在其他CLR语言中完全合法。例如在C＃中;


静态类XXX

{

const int A = 5;

}


编译没有任何错误。有没有办法在C ++ / CLI中的静态类中指定CLR兼容的参数

？

解决方案

你没有'在C＃中得到相同的数量。

那将是：

公共抽象密封类XXX

{

}

感谢您的回复。 Aref class XXX abstract sealed C ++ / CLI中的类

编译为.class abstract sealed XXX在MSIL中，这意味着静态

类XXX在C＃中。因此在您的示例中，您在C＃中使用相同的关键字，但

在语义上它们是不同的声明。


不知何故，C ++ / CLI编译器不允许我使用在一个

静态类中定义CLR常量，这通常在CLR中允许。

consts？

ref struct XXX abstract sealed
{
literal int A = 5;
};

The definition above gives me the compiler warning "C4693: a sealed abstract
class cannot have any instance members ''A''". The equivalent definition is
perfectly legal in other CLR languages. For example in C#;

static class XXX
{
const int A = 5;
}

compiles without any error. Is there a way to specify CLR compatible consts
in a static class in C++/CLI?

解决方案

You haven''t got the equivalent in C#.
That would be:
public abstract sealed class XXX
{
}

And the error message you get in C# is: "an abstract class cannot be sealed
or static".

Hi,

Thank you for your reply. A "ref class XXX abstract sealed" class in C++/CLI
is compiled to ".class abstract sealed XXX" in MSIL which means "static
class XXX" in C#. So in your example you use the same keywords in C#, but
semantically they are different declarations.

Somehow the C++/CLI compiler does not allow me to define CLR constants in a
static class, which is normally allowed in CLR.
