Question

使用MySql Workbench数据库中的数据填充DataGrid的最简单方法是什么？数据库名称是pop-sf40-database，它看起来像这样：

现在只有一个沙龙，我插入manualy。（localhost root root）

型号： 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;

    }
}

    </startup>
</configuration>

您似乎必须创建一个数据访问类。从架构上讲，这将放在应用程序的数据访问层（DAL）上。

您必须使用此对象从数据库中检索信息并填充Salon对象。如果您正在使用DataGrid，那么这可能意味着您将处理沙龙对象的列表（ObservableCollection）。
