从非托管code加载混合模式汇编

正如标题所说，我想打电话给从非托管code混合模式的组装。

As the title says i want to call a mixed mode assembly from unmanaged code.

要更precise，我想动态加载混合模式程序集，然后执行一些静态的非托管启动code，它注册了一些托管C ++包装的C＃code。

To be more precise, i want to load the mixed mode assembly dynamically and then execute some static unmanaged startup code that registers some Managed C++ Wrappers for C# Code.

这是可能的（或者我需要嵌入.NET运行时或使用COM？）？

Is this possible (or do i need to embed the .Net Runtime or use COM?) ?

有没有人已经做到了这一点，并可以分享一些经验？

Has anybody already done this and can share some experience?

PS：如果混合模式组件包括一个WPF窗口将它启动

PS: If the mixed mode assembly contains a WPF Window will it be started?

您需要让CLR加载和初始化。是的，使得管理类[标记有ComVisible特性]或托管的CLR自己与CorBindToRuntimeEx的（）是一个办法做到这一点。一个非常简单的方法就是从您的DLL导出一个管理功能，C ++ / CLI编译器嵌入到code，它需要初始化CLR照顾一个thunk。很容易做到，但它并没有很好地扩展在接口到你的管理code为脂肪。

You need to get the CLR loaded and initialized. Yes, making a managed class [ComVisible] or hosting the CLR yourself with CorBindToRuntimeEx() is a way to do this. A very simple way is to export a managed function from your DLL, the C++/CLI compiler embeds a thunk in the code that takes care of initializing the CLR. Very easy to do but it does not scale well when the interface to your managed code is fat.
```
ref class Bootstrap
{
public:
    static void Initialize() { 
        // etc..
    }
};

extern "C" __declspec(dllexport) 
void __stdcall LoadAndInitialize()
{
    Bootstrap::Initialize();
}
```
您可以通过传递函数指针到您的原生界面美化。将其转换为与元帅一个托管委托:: GetDelegateForFunctionPointer（）。不要忘了换任何本地声明使用#pragma如果你这样做管理。

You could embellish by passing a function pointer to your native interface. Convert it to a managed delegate with Marshal::GetDelegateForFunctionPointer(). Don't forget to wrap any native declarations with #pragma managed if you do this.
