C++ list determines which row is selected

 CString str;
      for(int i=0; i<m_list.GetItemCount(); i++)
      {
    
    
           if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED )
           {
    
    
                str.Format(_T("选中了第%d行"), i);
                AfxMessageBox(str);
           }
      }
