.net注册的dll在vb6中不显示功能 [英] .net registered dll does not show function in vb6

问题描述

net dll（PasswordHashLibrary）。创建项目后，我转到项目属性-> build->注册COM互操作。

net dll (PasswordHashLibrary) to be used in vb6 application. after creating the project, i went to project properties -> build -> Register for COM interop.

然后使用regasm命令将此dll注册到我的计算机上。
开始一个新的vb6项目->添加对PasswordHashLibrary的引用

Then registered this dll on my machine using regasm command. Started a fresh vb6 project -> added reference to PasswordHashLibrary

现在vb6项目允许我编写以下内容

Now the vb6 project allows me to write the following

Dim objHash As New PasswordHashLibrary.Hash

• PasswordHashLibrary =名称空间


• 哈希=类



我不能在其中调用任何函数（类和函数是公共的）

But it doesn't let me call any functions inside (class and functions are public)

例如，我有一个静态函数

for instance i have a static function

PasswordHashLibrary.Hash.HashPassword（ abc）

PasswordHashLibrary.Hash.HashPassword("abc")

它给出了编译时错误




未找到方法或数据成员

method or data member not found

当我尝试调试并在对象浏览器中查看时，没有成员

When i try to debug and look in object browser there is no member present

我的完整.Net代码

namespace PasswordHashLibrary
{
public class Hash
{
    private const int PBKDF2IterCount = 1000; // default for Rfc2898DeriveBytes
    private const int PBKDF2SubkeyLength = 256 / 8; // 256 bits
    private const int SaltSize = 128 / 8; // 128 bits

    public static string HashPassword(string password)
    {


        //my code goes here
    }

  }
}




推荐答案

我删除了静态属性，并添加了完成该操作的接口！

I removed the static attribute and added an interface that did the trick!

namespace PasswordHashLibrary
{
public interface ComClassInterface
{
}

public class Hash : ComClassInterface
{

    private const int PBKDF2IterCount = 1000; // default for Rfc2898DeriveBytes
    private const int PBKDF2SubkeyLength = 256 / 8; // 256 bits
    private const int SaltSize = 128 / 8; // 128 bits

    //[ComVisible(true)]
    public string HashPassword(string password)
    {
       //my code goes here
    }
  }
}
