怎么把下面的C++代码写成C#代码

如何把下面的C++代码写成C#代码？

C/C++ code

#include "stdafx.h"#include <Inventor\Win\SoWin.h>#include <Inventor\Win\viewers\SoWinExaminerViewer.h>#include <Inventor\nodes\SoCube.h>#include <Inventor\nodes\SoDirectionalLight.h>#include <Inventor\nodes\SoMaterial.h>#include <Inventor\nodes\SoPerspectiveCamera.h>#include <Inventor\nodes\SoSeparator.h>int main(int argc, char **argv){         HWND myWindow = SoWin::init(argv[0]);         if (myWindow == NULL)    exit(1);                 SoSeparator *root = new SoSeparator;         root->ref();         SoMaterial *myMaterial = new SoMaterial;         myMaterial->diffuseColor.setValue(1.0, 0.0, 0.0);         root->addChild(myMaterial);         root->addChild(new SoCube);                 SoWinExaminerViewer *myViewer = new SoWinExaminerViewer(myWindow);         myViewer->setSceneGraph(root);         myViewer->setTitle("Examiner Viewer");         myViewer->show();                 SoWin::show(myWindow);         SoWin::mainLoop();                 return 0;}

C# code

using OIV.Inventor.Win;using OIV.Inventor.Win.Viewers;using OIV.Inventor.Nodes;class program{   static void main(string[] args){
[解决办法]
得自己写命名空间啊？
还不如，把include的东西都作为成员函数
