如何从MySQL填充DataGrid

Question

What would be the simplest way to fill DataGrid with data from MySql Workbench database? Database name is pop-sf40-database and it looks like this:

For now there is only one salon which I insert manualy. (localhost root root)

Model: Salon.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace POP_SF_40_2014.Model
{
    class Salon
    {
        private int id;
        private string name;
        private string adress;
        private string telephone;
        private string email;
        private string web_site;
        private string tin;
        private string uid;
        private string bank_account;
        private bool deleted;

    }
}

Answer 1

It appears you will have to create a class for data access. Architecturally speaking, this will be placed on the Data Access Layer of your application (DAL).

You will have to use this object to retrieve information from your database and populate the Salon object. If you're using a DataGrid, then it probably means you'll be dealing with a list (ObservableCollection) of Salon objects.

Here is a good thread on best practices when writing a DAL
