}
错误提示如下：
1>d:/projects/add/add/Form1.h(122) : error C2039: 'OK' : is not a member of 'System::Windows::Forms::Form::DialogResult'
1> d:/projects/add/add/Form1.h(22) : see declaration of 'System::Windows::Forms::Form::DialogResult'
1>d:/projects/add/add/Form1.h(122) : error C2065: 'OK' : undeclared identifier
解决办法：
openFileDialog1->ShowDialog()==System::Windows::Forms::DialogResult::OK)
原因：
Because DialogResult is a existing member of the Form.
