Generic Entity Base

Hi 😀

How it works?

Using the power of interfaces, we create a entity base model that can be inherited from.

To help us a litle bit more, Hi 😀 we implement those interfaces into two 😀abstract 😀c 😀classes Entity Hi 😀 Entity<T>. The first must be used for entities with composite primary key and the seconde one shall be used for entities with single primary key where the gereric type <T> will be the primary key type.

All the properties of both abstract classes are virtual and can be overrided if needed. A good example of this kind of need is: we dont't want store one of those properties into database, and to acomplish this, we need mark this property with [NotMapped] attribute.

How to use this extension?

Here is a entity with composite primary key:

public class MyEntityWitCompositeKey : Entity
{
    public int EntityFirstCompsiteKey { get; set; }
    public int EntitySecondCompsiteKey { get; set; }

    [NotMapped]
    public override DateTime ModifiedDate { get; set; }

    public override object GetId()
    {
        return new object[] { EntityFirstCompsiteKey, EntitySecondCompsiteKey };
    }
}

And a entity with integer primary key

public class MyEntity : Entity<int>
{
    public override int Id { get; set; }

    [NotMapped]
    public override string ModifiedBy { get; set; }
}

Where to get this extension?

You can install this extension direct from Nuget:

Install-Package LMB.GenericEntityBase

Or you can download this github project and copy the Entity.cs file, along with all interfaces files, direct into your project.
