c# loops serialization

C# 除了从2017/06/01到2017/07/01将日期增加1外，如何在不修改内容的情况下循环序列化列表,c#,loops,serialization,C#,Loops,Serialization,我正在尝试循环浏览一个列表，并将其复制几次，除了日期之外不做任何修改。我需要将日期从2017/06/01-2017/07/01增加1，但每次我尝试将日期跳转到我指定的月份，该月份前的每一天除外，并且添加的最后一项会重复一次又一次，而不是重复整个列表。下面是我的代码以及我不断得到的输出 using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using Syste

如果没有完整的代码，很难说如何填写新的FlightFactorys（/*此处为增量日期*/），但您应该了解这一点。

“每次我尝试填写时，日期都会跳到我指定的月份”，但您没有指定任何月份。您能回顾一下您的问题描述吗？所示月份为07或7月份。因此它从2017年1月6日跳到2017年1月7日，如图所示。@user2792215-您需要提供一个。除非我们能自己运行你的代码，否则无法正确测试。为什么
Date
是
int
而不是
DateTime
？我真的不知道这一点。这是我的第一个C#程序，我还在学习。你认为改变它会有帮助吗？
