如何在C ++ / CLI包装器中全局声明C＃dll [英] How to declare C# dll globally inside C++/CLI wrapper

问题描述

我已经创建了用于调用C＃dll方法和事件的C ++ / CLI包装器。我在C ++ / CLI包装器项目中引用了C＃dll。我调用了由colorinitialize（）和colorclientconnect（）组成的connect1方法。从C＃dll调用。以下代码用于在C ++ / CLI包装器中调用C＃dll。



NativeInterface.h

I have created C++/CLI wrapper for calling C# dll methods and events.I have referenced C# dll in the C++/CLI wrapper project.I have called connect1 method which consists of colorinitialize() and colorclientconnect() both have to be called from C# dll.The following code i have used for calling C# dll with in C++/CLI wrapper.

NativeInterface.h

extern "C"{
   __declspec(dllexport) const char*  Connect1(char* str, int port);
    __declspec(dllexport)  const char*  Test(char* str, int port);
    };

SampleWrapper.cpp（C ++ / CLI包装器）

SampleWrapper.cpp (C++/CLI wrapper)

#include "NativeInterface.h"
namespace Wrapper
{
#ifdef __cplusplus
extern "C"
{
#endif

            __declspec(dllexport)  const char*  Test(char* str, int port)
            {

                KinectV2Server::KinectV2 c1;

                c1.GetBytes();
                return str;
            }

            //String tmp;

            __declspec(dllexport)  const char*  Connect1(char* str, int port)
            {
                  KinectV2Server::KinectV2 c1;

                c1.ColorInitialize();
                c1.ColorClientConnect(gcnew System::String(str));


                return  str;
            }

        #ifdef __cplusplus
}
#endif
}

之后我将在另一个C ++应用程序中调用此C ++ / CLI包装器，



C ++应用程序：

After that i will call this C++/CLI wrapper in another C++ application like this,

C++ application:

#include "SampleCPlusApps.h"
#include <math.h>
#include "Time.h"
#include "NativeInterface.h"

SampleCPlusApps::SampleCPlusApps(void)
{
    float smoothing = 0.7f;  //0.25f        // [0..1], lower values closer to raw data
    float correction = 0.3f; //0.25f        // [0..1], lower values slower to correct towards the raw data
    float prediction = 1.00f;  //0.25f       // [0..n], the number of frames to predict into the future
    float jitterRadius =  1.0f; // 1.03f;     // The radius in meters for jitter reduction
    float maxDeviationRadius = 1.0f;; //0.05f;// The maximum radius in meters that filtered positions are allowed to deviate from raw data

    fde.Init(smoothing, correction, prediction, jitterRadius, maxDeviationRadius);
    //initialization();

    //const char* test1;
    //test1= ("Hai", 1);
}

int SampleCPlusApps::Initialization()
{
const char* test;
    test = Connect1("197.1.1.1",1524); // my wrapper class is called here

}

所以从上面的代码中，我对SampleWrapper.cpp（C ++ / CLI包装器）有疑问。我已经声明了我的c＃dll（KinectV2Server :: KinectV2） c1）方法内部。



但是我需要全局声明c＃dll，以便它可以在两个函数中使用，即connect1和test。



请帮助我解决问题。



谢谢

so from my above code, i have doubt in SampleWrapper.cpp (C++/CLI wrapper).Here i have declared my c# dll(KinectV2Server::KinectV2 c1) inside the method.

But i need to declare the c# dll globally, so that it can be used in both functions namely connect1 and test.

Please assist me to fix the issue.

Thanks

推荐答案

您需要全局声明它，因为每个函数都有自己的作用域。解决方案是您声明一些全局函数。例如：

You need to declare it globally because every function has its own scope. A solution would be that you declare some global functions. Like:

bool InitServer();//start up
KinectV2Server::KinectV2* GetServer();//access (in the dll OR for external use)
void ExitServer();//shut down

对于GetServer（）可以很方便地使用void *以避免一些hazzle。

for the GetServer() could be handy to use a void* to avoid some hazzle.
