C++ 判断本机是否有.Net环境

int main(int argc, char* argv[]) 

{ 

    char winDir[256]={0}; 

    GetWindowsDirectory(winDir, 256); 

    //strcat(winDir,"\\Microsoft.Net\\"); 

    printf("%s\n",winDir); 

    //test .net exist. 

    char tcProgramFile[MAX_PATH] = {0}; 

    SHGetSpecialFolderPath(NULL,tcProgramFile,0x26,0);  

    strcat(tcProgramFile,"\\Microsoft.NET"); 

    printf("%s\n",tcProgramFile); 

    HANDLE hFind; 

    WIN32_FIND_DATA FindFileData; 

    hFind = FindFirstFile(tcProgramFile,&FindFileData); 

    if(hFind == INVALID_HANDLE_VALUE) 

    { 

        printf(".Net not exist!\n"); 

        exit(1); 

    } 

    else 

    { 

        printf(".Net environment ok!\n"); 

    } 

        return 0;
