For the EF Code First model entity, have a custom Setter on the property.

Question
Is it feasible to modify or add code to the entity model object's property setter using the EF Code First approach?
e.g.
public class Contact
{
[Key]
public int Id { get; private set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string JobTitle
{
get;
set { // eg. proper case the job title }
}
}
I had attempted to set/get to a private or protected property that is by having a public property designated as NotMapped. But it seems that in order to be formed in a table, the attribute must be made public.
Accepted Answer
If you'd like, you may add logic there; just change the property's status to non-automatic and carry out the checks as you normally would with a regular property.
private string jobTitle;
public string JobTitle
{
get { return jobTitle; }
set
{
// do your fancy stuff or just jobTitle = value
}
}
Keep in mind that any changes you make to the value from the database inside of your setter will likely be stored in that manner.SaveChanges()
on the surroundings.

Description
The property may be disregarded by using theModelBuilder
and .Ignore(...)
.Ignore(...) Excludes a property from the model so that it will not be mapped to the database.
Sample
public class MyDbContext : DbContext
{
public DbSet<Contact> Contact { get; set; }
// other DbSet's
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<Contact>().Ignore(x => x.JobTitle);
}
}
