ArrayList add方法(转)

由于 BrowerList 输出结果都是最后一条记录,后来网上查到了

                    if (dRead.HasRows)
                    {
　　　　　　　　　　　　　　List<Class_RejectQuery> BrowerList = new List<Class_RejectQuery>();
                        Class_RejectQuery listRow = new Class_RejectQuery();    
                        while (dRead.Read())
                        {
                            listRow.id=dRead.GetString(0);   
                            listRow.sn = dRead.GetInt32(1);     
                            listRow.times = dRead.GetInt32(2);   
                            listRow.cause = dRead.GetString(3);   
                            listRow.auditor = dRead.GetString(4);        
                            listRow.customer = dRead.GetString(5);  
                            listRow.department = Convert.IsDBNull (dRead [6])?"": dRead.GetString(6);    
                            listRow.targetPerson = dRead.GetString(7);    
                            listRow.recordName= Convert.IsDBNull (dRead[8] ) ? "" : dRead.GetString(8);   
                            listRow.auditDate = dRead.GetString(9);     
                            BrowerList.Add(listRow);
                        }
                    }

 仅仅是位置不同而已,结果却相大不相同

 1                     if (dRead.HasRows)
 2                     {
 3 　　　　　　　　　　　　　　List<Class_RejectQuery> BrowerList = new List<Class_RejectQuery>();
 4                          5                         while (dRead.Read())
 6                         {
　　　　　　　　　　　　　　　　　　Class_RejectQuery listRow = new Class_RejectQuery(); 
 7                             listRow.id=dRead.GetString(0);   
 8                             listRow.sn = dRead.GetInt32(1);     
 9                             listRow.times = dRead.GetInt32(2);   
10                             listRow.cause = dRead.GetString(3);   
11                             listRow.auditor = dRead.GetString(4);        
12                             listRow.customer = dRead.GetString(5);  
13                             listRow.department = Convert.IsDBNull (dRead [6])?"": dRead.GetString(6);    
14                             listRow.targetPerson = dRead.GetString(7);    
15                             listRow.recordName= Convert.IsDBNull (dRead[8] ) ? "" : dRead.GetString(8);   
16                             listRow.auditDate = dRead.GetString(9);     
17                             BrowerList.Add(listRow);
18                         }
19                     }
