我用VS2008,建立一个工程ATLProject1,里面先有一个VC建立的ATL工程,有一个组件叫做Fun,接口叫做IFun,函数叫做Add([in] int n1,[in] int n2,[out,retval] int* pVal). 编译成功,自动注册。然后我建立一个C#的工程,敲入以下代码:using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ATLProject1Lib;
namespace cs_ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
IFun f = new FunClass();
Console.WriteLine(f.Add(2, 3));
}
}
}运行调试到了IFun f=new FunClass();这一句出错了,如下:
Additional information: Retrieving the COM class factory for component with CLSID {6FB1F141-A978-420B-892B-6DB29610F314} failed due to the following error: 80040154.'cs_ConsoleApplication1.vshost.exe' (Managed): Loaded 'C:\WINDOWS\assembly\GAC_MSIL\System.Configuration\2.0.0.0__b03f5f7f11d50a3a\System.Configuration.dll'
The program '[520] cs_ConsoleApplication1.vshost.exe: Managed' has exited with code 0 (0x0).我把这句改成了这样也不行: IFun f = new Fun();这是为什么呢?
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ATLProject1Lib;
namespace cs_ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
IFun f = new FunClass();
Console.WriteLine(f.Add(2, 3));
}
}
}运行调试到了IFun f=new FunClass();这一句出错了,如下:

我重新创建了一个ATLProject2生成一个com组件
谢谢。问题是:64位的com组件是用什么命令进行注册的? regsvr32是注册32位组件的吧?但是我的win7 64位系统里面并不能找到名叫regsvr64的程序。然后我按照你说的,devenv /useenv启动VS,进入VS打开工程新建一个x64的配置,编译ATL工程以及C#工程。都能编过,但是这次运行提示连库类都找不到了:Unhandled Exception: System.Runtime.InteropServices.COMException: Retrieving the
COM class factory for component with CLSID {2BFFD823-9C32-4661-87F2-6B453E0C3F6

1.在编译你的dll时,将其定义为com组件;
2.生产dll之前,对程序集进行签名(Choose a strong name key 下选择new,写入自己的key file name)
3.生成dll
4.注册dll
a.以管理员运行cmd,转到你的RegAsm.exe所在的.net 框架文件夹,并运行如下命令,如:我的.net 框架在(C:\Windows\Microsoft.NET\Framework64\v2.0.50727)——(dll路径:C:\xx\xx.dll),如下:
C:\Windows\Microsoft.NET\Framework64\v2.0.50727>regasm /codebase C:\xx\xx.dll
ok 了
在工程配置里面要把Any CPU 改成X86,像这样:
然后就能输出结果16了
