.NET DLL不会导出任何内容

Question

我最近在F＃中创建了一个DLL库。我从来没有为.NET Framework创建过DLL，但我已经用纯Win32 C ++编写了一对。通常，当我编写C ++ DLL时，我使用了像this之类的实用程序来查看我的函数是否已正确导出。通常，它工作，但当我审查我在F＃中制作的DLL时，它没有显示导出的函数。这是我的构建问题吗？还是.NET DLL没有明确导出任何东西？

顺便说一下这是我的构建输出：

Answer 1

您没有使用@ Ryan评论中提到的正确工具。

与C ++ DLL导出表类似，.NET DLL公开其＆＃34;函数和类（以及其他信息）＆＃34;通过a set of tables in CLR metadata。

  

CLR元数据被组织为规范化的关系数据库。这意味着CLR元数据由彼此之间具有外键的矩形表组成。如果您以前有过数据库方面的经验，那么您应该熟悉这个概念。从.NET 2.0开始，有超过40个表定义了CLR元数据。以下是一些表格的示例列表：

     

模块（0x00） - 包含有关当前模块的信息

     

TypeRef（0x01） - 包含有关从其他模块引用的类型的信息

     

TypeDef（0x02） - 包含有关当前模块中定义的类型的信息

     

字段（0x04） - 包含有关当前模块中定义的字段的信息

     

方法（0x06） - 包含有关当前模块中定义的方法的信息

     

属性（0x17） - 包含有关当前模块中定义的属性的信息

     

汇编（0x20） - 包含有关当前汇编的信息   AssemblyRef（0x23） - 包含有关引用程序集的信息

请注意，不仅＆＃34;导出＆＃34; （公共类型和方法）是可见的，内部或私有的类型和方法也是可见的。
