格式datetime dd/mm/yyyy

Question

如何將日期時間屬性格式化爲日期格式dd/mm/yyy並返回爲jsonResults？這是我的代碼：

var alljobs = from jobs_new in db.Jobs_New 
    select new { 
     jobs_new.JobID, 
     //below code not working 
     DateReceived = jobs_new.DateReceived.GetValueOrDefault().ToString("dd/mm/yyyy") 
    }; 

Answer 1

由於您DateReceived似乎是一個字符串，你首先需要DateTime.Parse()它，這LINQ到實體不支持。所以，你可以只加載的一切首先，然後做轉換算賬：

var alljobs = (from jobs_new in db.Jobs_New).ToList(); 

var alljobsWithDate = from alljobs 
      select new { 
       jobs_new.JobID, 
       DateReceived = string.IsNullOrEmpty(jobs_new.DateReceived.GetValueOrDefault()) ? null : DateTime.Parse(jobs_new.DateReceived.GetValueOrDefault().ToString("dd/MM/yyyy") 
      }; 

你可以通過別的東西，如果日期爲空或空，在? "if date is empty" :

Answer 2

try代碼：

var alljobs = (from jobs_new in db.Jobs_New.AsEnumerable() 
    select new{ 
     jobs_new.JobID, 
     DateReceived = jobs_new.DateReceived==null?"":jobs_new.DateReceived.ToString("dd/mm/yyyy") 
    }).ToList();
