实体框架在C＃中按ID更新记录 [英] entity framework update record by id in c#

问题描述

我是新使用的实体框架

如何将其转换为实体框架c＃

query = update cachieroperation set last_used = getdate（）+'0：8：0'其中id = 14

How can I convert this to entity framework c#
query = "update cachieroperation set last_used = getdate()+'0:8:0' where id = 14"

推荐答案

应该是这样（我不知道您的类叫什么）：

Should be something like(I don't know what your classes are called):

using(var context = new SomeEntities())
{
     CarrierOperation carrierOperation = context.CarrierOperations.SingleOrDefault(co=> co.id == 14);
     if(carrierOperation != null)
     {
         carrierOperation.last_used = DateTime.Now.AddMinutes(8);
         context.SaveChanges();
     }
}
