How to use generic type with the database Context in EF6 Code First

Question

For example, let say I have 4 different entity that each implement a Add() method that add the entity to the database :

public class Profile
{
    ...

    publi         


        

Answer 1

You could get around that be the following; you just have to make sure at runtime it really is a TEntity:

public void Add()
{
    object obj = this;
    this._dbContext.Set().Add((TEntity)obj);
    this._dbContext.SaveChanges();
}

Since the compiler loses track of what this is when you use an object type. If you get an error, it's because obj is not truly a TEntity. However, you may want to use a factory, repository, or other design pattern for working with the entity framework DBSet.
