asp.net c＃控制器代理怪异

Question

首先，这个问题的名称不是很好，但我想不出一个更好的。 我正在开展一个项目，我每天都会报道不同的项目。

这是它的样子。

但现在的问题是，如果我将它提交它会像这样结束。

就像我们可以在这里看到在每月的总结，是对谢胜利，迄今为止，它复制该项目，并显示它的两倍，这happends如果我添加更多的日期。 但是它从未在第一次约会中发生。

我已经调试它，但我没有看到它的时候跑了第一次，所有的值相同等

这是控制器

Answer 1

它wasen't做怪，在foreach循环的最后我有这个if语句

     if (ModelState.IsValid) 
        { 
         projectData.SaveToDatabase(Constants.CurrentUser(User.Identity.Name)); 
         ViewData["posted"] = true; 

         //Loads default settings and projects. 
         projectData = new NewTimeReportModel(); 
         LoadDefaultSettings(projectData); 

        } 

这最后像LoadDefaultSettings(projectData);加载所有设置再次，所以在它保存了第一个日期之后，它会在下一次日期再次加载所有设置。他们得到了重复。所以我只是将这一点从foreach中移除。
