如何使用.net汇编从Win32没有注册？ [英] How to use .Net assembly from Win32 without registration?

问题描述

我想动态加载并使用Delphi Win32应用程序在C＃中创建的.Net程序集。我的类和接口被标记为ComVisible，但是我想避免注册程序集。
这是可能吗？

I'd like to dynamically load and use a .Net assembly created in C# from a Delphi Win32 application. My classes and interfaces are marked as ComVisible, but I would like to avoid registering the assembly. Is this possible?

我在这里找到了链接文本另一个很好的讨论话题，但它更多地是托管CLR。哪个提出一个问题 - 为什么要使用ClrCreateManagedInstance来承载CLR？

P.S. I found here link text another good discussion on the topic, but it is more around hosting the CLR. Which begs a question - why would you host CLR versus using ClrCreateManagedInstance?

推荐答案

奇怪的是，我找不到答案StackOverflow，并没有太多的网络，特别是对于Delphi。我发现实例的解决方案发布了 here 。
这是我在最后得到的：

Strangely enough, I couldn't find an answer on StackOverflow, and there is not much on the Net, especially for Delphi. I found the solution from examples posted here. Here's what I got at the end:

function ClrCreateManagedInstance(pTypeName: PWideChar; const riid: TIID;
out ppObject): HRESULT; stdcall; external 'mscoree.dll';

procedure TMyDotNetInterop.InitDotNetAssemblyLibrary;
var
  MyIntf: IMyIntf;
hr: HRESULT;
NetClassName: WideString;
begin
//Partial assembly name works but full assembly name is preffered.
    NetClassName := 'MyCompany.MyDLLName.MyClassThatImplementsIMyIntf,
          MyCompany.MyDLLName';
    hr := ClrCreateManagedInstance(PWideChar(NetClassName), IMyIntf, MyIntf);
    //Check for error. Possible exception is EOleException with ErrorCode
    //FUSION_E_INVALID_NAME = $80131047 2148732999 : The given assembly name 
    //or codebase was invalid.
    //COR_E_TYPELOAD = $80131522 - "Could not find or load a specific type 
    //(class, enum, etc)"
    //E_NOINTERFACE = $80004002 - "Interface not supported".
    OleCheck(hr);
end;

BTW根据情况，您可能需要动态加载mscoree.dll，因为它可能是不存在于系统上（没有.Net框架的XP）

BTW, depending on the situation, you might want to load mscoree.dll dynamically, because it might be not present on the system (XP with no .Net Framework)

编辑：不幸的是，这是已被弃用的，并停止使用.Net4，我刚刚发现。这只剩下两个选项 - CLR托管和非托管导出。另外， .Net4 COM代码的调试被破坏。

Unfortunately, this was deprecated and stopped working with .Net4 as I just found out. This leaves only two options - CLR hosting and unmanaged export. Also, debugging of .Net4 COM code is broken.
