使用Dapper.NET将2个SQL表列值添加到一个C＃属性

Question

I have a class Department .

Deparment has one property called Address .

I have a SQL table called Deparment .

This Department has 2 columns Address1 and Address2 .

I use Dapper.net and would like to put the two SQL table columns into the one property of my class.

How ? Thank!

Answer 1

I would do:

public class Department {
    public string Address1 {get;set;}
    public string Address2 {get;set;}

    public string Address {
        get { return Address1 + Environment.NewLine + Address2; }
    }
}

Answer 2

Are you using this for "Read-Only". How would you expect your ORM to write the data back to the database ?

If it is read-only, instead of querying the table directly, you could wrap it in a view.

CREATE VIEW DepartmentView
(
    SELECT Address1 + ', ' + Address2 as Address FROM Department
)

and then just map the view instead.
