以编程方式查找完全限定的.NET程序集名称（从简单名称，对于给定的.NET版本）？

我的目标是从纯C本机Windows API级程序（不是托管C或C / CLI）显示.NET Windows窗体消息框 .

也就是说，出于学习目的，我想在纯C中实现下面注释中显示的C＃代码：

/*
    // C# code that this C++ program should implement:
    using System.Windows.Forms;

    namespace hello
    {
        class Startup
        {
            static void Main( string[] args )
            {
                MessageBox.Show(
                    "Hello, world!",
                    ".NET app:",
                    MessageBoxButtons.OK,
                    MessageBoxIcon.Information
                    );
            }
        }
    }
*/

        )
        >> Is< HrSuccess >()
        || throwX( "CorBindToRuntimeEx failed" );

    pCorRuntimeHost->Start()    // Without this GetDefaultDomain fails.
        >> Is< HrSuccess >()
        || throwX( "CorRuntimeHost::Start failed" );

    IUnknownPtr     pAppDomainIUnknown;
    pCorRuntimeHost->GetDefaultDomain( &pAppDomainIUnknown )
        >> Is< HrSuccess >()
        || throwX( "CorRuntimeHost::GetDefaultDomain failed" );

    AppDomainPtr    pAppDomain  = pAppDomainIUnknown;
    (pAppDomain != 0)
        || throwX( "Obtaining _AppDomain interface failed" );

    // This fails because Load requires a fully qualified assembly name.
    // I want to load the assembly given only name below + relevant .NET version.
    AssemblyPtr     pFormsAssembly;
    pAppDomain->Load_2( _bstr_t( "System.Windows.Forms" ), &pFormsAssembly )
        >> Is< HrSuccess >()
        || throwX( "Loading System.Windows.Forms assembly failed" );    

    // ... more code here, not yet written.
}

int main()
{
    try
    {
        cppMain();
        return EXIT_SUCCESS;
    }
    catch( std::exception const& x )
    {
        std::cerr << "!" << x.what() << std::endl;
    }
    return EXIT_FAILURE;
}

计划是，在加载程序集后，继续 MessageBox 类并调用 Show . 但这可能是一种错误的做法 . 所以我同样很满意答案显示如何在没有找到程序集的完全限定名称的情况下执行此操作（当然，没有硬编码完全限定名称！） .

gacutil 实用程序显然能够找到完全限定的名称：

C:\test> gacutil /l System.Windows.Forms
Microsoft (R) .NET Global Assembly Cache Utility.  Version 4.0.30319.1

The Global Assembly Cache contains the following assemblies:

Number of items = 4

C:\test> _

但是，如上所述，我不想硬编码任何东西：C代码中硬编码的.NET信息不应超过顶部注释中显示的C＃源代码，加上支持的最小.NET版本 .

TIA，
