Question

我正在尝试使用c ++ Visual Studio 2010中的Windows应用程序表单浏览文件。此代码会出现以下错误。任何人都可以帮助解决问题

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {

      Stream^ myStream;
      OpenFileDialog^ openFileDialog1 = gcnew OpenFileDialog;

      openFileDialog1->InitialDirectory = "c:\\";
      openFileDialog1->Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
      openFileDialog1->FilterIndex = 2;
      openFileDialog1->RestoreDirectory = true;

      if ( openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK )
      {
            if ( (myStream = openFileDialog1->OpenFile()) != nullptr )
            {
                // Insert code to read the stream here.
                myStream->Close();
            }
      }

}
