如何访问由DataTable返回的另一个类中的值，并将其绑定到三层体系结构的C#中的网格视图

public class MyEntity
{
    public string Column1 { get; set; }
    public int Column2 { get; set; }
    // 其他属性...
    
    public static List<MyEntity> ConvertDataTableToEntities(DataTable dataTable)
    {
        List<MyEntity> entities = new List<MyEntity>();
        
        foreach (DataRow row in dataTable.Rows)
        {
            MyEntity entity = new MyEntity();
            entity.Column1 = row["Column1"].ToString();
            entity.Column2 = Convert.ToInt32(row["Column2"]);
            // 其他属性赋值...
            
            entities.Add(entity);
        }
        
        return entities;
    }
}

public class MyDataAccessLayer
{
    public DataTable GetData()
    {
        // 获取DataTable的代码...
    }
    
    public List<MyEntity> GetEntities()
    {
        DataTable dataTable = GetData();
        return MyEntity.ConvertDataTableToEntities(dataTable);
    }
}

public class MyBusinessLogicLayer
{
    private MyDataAccessLayer dataAccessLayer;
    
    public MyBusinessLogicLayer()
    {
        dataAccessLayer = new MyDataAccessLayer();
    }
    
    public List<MyEntity> GetEntities()
    {
        return dataAccessLayer.GetEntities();
    }
}

protected void Page_Load(object sender, EventArgs e)
{
    MyBusinessLogicLayer businessLogicLayer = new MyBusinessLogicLayer();
    List<MyEntity> entities = businessLogicLayer.GetEntities();
    
    GridView1.DataSource = entities;
    GridView1.DataBind();
}
