如何从DLL创建类的新实例?

我正在转换用编码的旧应用程序 VB6 到 VB.NET .

在旧的应用程序中,我使用的是第三方 DLL 文件。我们称之为 ThirdParty.dll .

我的习惯之一 ThirdParty.DLL 就像在 vb6 以下内容:

Dim MyApi as new x.y 'referenced from the ThirdParty.dll
Dim vReturnCode as Long

vReturnCode = MyAPI.InitialiserCles(a, b, c, d, e) 'consider a,b,c,d,e variables declared and initiaited.

在旧应用程序中,这将返回一个结果 Long .

现在,我需要用同样的方法 第三方.dll 在我的新的 vb.net版 应用程序。

我创造的是:

Public Class ThirdPartyAPI
    Private Declare Function InitialiserCles Lib "ThirdPartyFolder\ThirdParty" (a As String, b As String, c As String, d As String, ByRef e As String) As Long

    Public Function InitializeKey(a As String, b As String, c As String, d As String, ByRef e As String) As Long
        Return InitialiserCles(a, b, c, d, e)

    End Function
End Class

现在,当我想使用它时,我是这样做的:

Dim MyApi as new ThirdPartyAPI
Dim result as MyApi.InitialiserCles(a,b,c,d,e) 'consider again variables are well declared/initiated.

我收到以下错误:

在dll ThirdpartyFolder\Thirdparty中找不到dll入口点“Initializers”

我想这是因为我们实际上正在创建 x.y 从该dll,然后调用函数 InitialiserCles (在旧应用(vb6)中)。我也没能做到 vb.net版 .我错过了什么?
