推荐答案

给出的示例是C ++/CLI.标准C ++会完全不同，但仍然微不足道.

The example you were given was C++/CLI. Standard C++ will be totally different, but still trivial.

是的.
而且不会困难.
:)

Yes you can.
And it won''t be difficult.

简单示例:)

Simple example :)

FileStream* OpenFile()
   {
       // Displays an OpenFileDialog and shows the read/only files.

       OpenFileDialog* dlgOpenFile = new OpenFileDialog();
       dlgOpenFile->ShowReadOnly = true;

       if (dlgOpenFile->ShowDialog() == DialogResult::OK) {
           // If ReadOnlyChecked is true, uses the OpenFile method to
           // open the file with read/only access.
           if (dlgOpenFile->ReadOnlyChecked == true) {
               return dynamic_cast<FileStream*>(dlgOpenFile->OpenFile());
           }

           // Otherwise, opens the file with read/write access.
           else {
               String* path = dlgOpenFile->FileName;
               return new FileStream(path, System::IO::FileMode::Open,
                   System::IO::FileAccess::ReadWrite);
           }
       }
       return 0;
   }
