如何在Entity Framework中使用DataBase中的默认列值？ [英] How to use Default column value from DataBase in Entity Framework?

问题描述

我在表中有一个Date列，它具有默认值或绑定为getutcdate（）。我想在实体框架中使用。在生成EDM时，我能够在列级别找到默认值属性，但我认为这是硬编码的值。

I have a Date column in table which has default value or binding as getutcdate(). I want to use this in entity framework.On generating EDM I was able to find "Default Value " property at column level but I think it is for hardcoded value.

请让我知道如何使用数据库中指定的默认值。

Please let me know how can I use default value specified in database.

推荐答案

为实体实现OnCreated事件是我发现的解决方案。我有一个Guid属性，我想要填充。默认情况下，它正在填充全零（00000-0000-00000-etc）。通过将以下内容添加到我能够处理该问题的实体的部分类中。

Implementing the OnCreated event for the entity is the solution I have found. I had a Guid property that I wanted to be populated. By default it was being populated with all zeros (00000-0000-00000-etc). By adding the following to my partial class of the entity I was able to deal with the issue.

partial void OnCreated()
{
    Guid = Guid.NewGuid();
}
