asp.net c＃控制器代理怪異

Question

首先，這個問題的名稱不是很好，但我想不出一個更好的。 我正在開展一個項目，我每天都會報道不同的項目。

這是它的樣子。

但現在的問題是，如果我將它提交它會像這樣結束。

就像我們可以在這裏看到在每月的總結，是對謝勝利，迄今爲止，它複製該項目，並顯示它的兩倍，這happends如果我添加更多的日期。 但是它從未在第一次約會中發生。

我已經調試它，但我沒有看到它的時候跑了第一次，所有的值相同等

這是控制器

任何不同勢行爲

Answer 1

它wasen't做怪，在foreach循環的最後我有這個if語句

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

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

        } 

這最後像LoadDefaultSettings(projectData);加載所有設置再次，所以在它保存了第一個日期之後，它會在下一次日期再次加載所有設置。他們得到了重複。所以我只是將這一點從foreach中移除。
