[英]Detecting when POCO entities are being initialized in Entity Framework
Let's say I have a POCO with a property as such 假设我有一个POCO具有这样的属性
public class Person
{
private string _firstName;
public string FirstName
{
get { return _firstName; }
set
{
_firstName = value;
// DO STUFF;
}
}
}
When the object is being initialized by EF, I only want _firstName
to be set and nothing else, only after the object is initialized do I want a set to run the rest // DO STUFF;
当对象由EF初始化时,我只希望设置_firstName
,而别无其他,只有在对象初始化之后,我才希望集合运行其余的// DO STUFF;
. 。
Why don't you simply 你为什么不简单
protected
; 宣布财产保护者为protected
保护者; and 和 // DO STUFF
behavior as a proper method SetFirstName(string firstName)
? 将您的// DO STUFF
行为公开为适当的方法SetFirstName(string firstName)
? Something like this: 像这样:
public class Person
{
public string FirstName { get; protected set; }
public string SetFirstName(string value)
{
_firstName = value;
// DO STUFF;
}
}
Much cleaner, don't need to "hack" EF at all. 更清洁,根本不需要“破解” EF。
