get UserId and nameId with Entity Framework login

Question

Good afternoon, I am working with Entity Framework, C # and Sql server, in a project, I have this method for login, which works correctly. 

public static bool ValidarUsuario(string Usuario, string Password)
{
    using (GourmetEntities db = new GourmetEntities())
    {
        // bcryp para encriptar, buscar información
        var Usu = from u in db.tblUsuarios
                  where u.Usuario == Usuario && u.Password == Password
                  select new { u.Usuario,u.Perfil_Id};
        if (Usu.Count() > 0)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
}

but after that I need to get the UserId, UserName, and profileId to perform other operations, and I would like to save them in session variables, please how can I do that, since the return of my method is bool. This is the code of my button

private void BtnIngresar_Click(object sender, EventArgs e)
{
    if(CapaDatos.tblUsuario.ValidarUsuario(TxtUsuario.Text, TxtPassword.Text))
    {
        FrmPadre frmPadre = new FrmPadre();
        frmPadre.Show();
    }
    else
    {
        return;
    }
}

Now with Entity Framework and linq I generate this sql server code which brings me the data I need,

but I don't know how to get it in c #

declare @p__linq__0 varchar(30) set @p__linq__0 = 'rmelgar';
declare @p__linq__1 varchar(30)  set @p__linq__1 = '123456789sc';
SELECT
    1 AS [C1],
    [Extent1].[Usuario] AS [Usuario],
    [Extent1].[Perfil_Id] AS [Perfil_Id]
    FROM [dbo].[tblUsuarios] AS [Extent1]
    WHERE ([Extent1].[Usuario] = @p__linq__0) AND ([Extent1].[Password] = @p__linq__1)

Please can you help me solve my problem, thank you very much

 

Please excuse me, I still don't know how to use the forum, I think I have formats that should not be
