在VB6应用消费.NET的DLL [英] Consuming .NET dll in VB6 application

问题描述

我写在C＃.net一个DLL调用该应用程序中的其他第三方.NET的DLL。这工作得很好，当我写在C＃.NET控制台应用程序测试它使用下面的代码，以及：

I wrote a dll in c#.net that calls another third party .NET dll within the application. This works fine when I tested it with a console application written in c#.NET as well using the code below:

 Assembly u = Assembly.LoadFrom(dllLocation);
 Type t = u.GetType("MyLIB.CLass");
 MethodInfo m = t.GetMethod("Method");
 object[] myparam = new object[1];
 myparam[0] = fileLocation;
 result = (string)m.Invoke(null, myparam);

请注意，某些文件所在的DLL最初加载以及使用的位置中加载：

Please note that some files are loaded within the location where the dll was initially loaded as well using:

  string path = Assembly.GetExecutingAssembly().Location;
  path = Path.GetDirectoryName(path);

但问题是，当我试图呼叫使用VB6，我得到一个错误，它无法加载第三方DLL。请帮助我似乎不知道发生了什么事情。

But the issue is that when I tried to call it using VB6, I get an error that it cannot load the third party dll. Please help as I seem not to know what's going on.

推荐答案

我想给你更多的细节，以便.NET大会暴露在COM

I would thought to give you more detail, in order .NET Assembly expose to COM

您需要生成 TBL - 类型库

使用 RegAsm / TLB：MyLIB.tlb中是指mylib.dll

有指南以揭露.NET类型为COM，并确保你应付的。
，如申报的 ComVisibleAttribute ，需要一个公共的默认构造函数是可见的COM，如在

There are Guidelines to expose .NET Types to COM and make sure you cope with that. such as declare ComVisibleAttribute , require a public default constructor to be visible to COM , such are in
