Question

我有gridview，我想从数据库绑定它，但它不绑定一些单元格。这是一类表：

mod

这是我的绑定代码

public class Break
{
    #region Property
    [Key]
    [Required]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    [Column("FldKeyId")]
    public int MyKeyId { get; set; }
    [Required]
    public Machine Machine { get; set; }  
    [Required]
    public Employee Employee { get; set; }
    [Required]
    public Shift Shift { get; set; }
    [Required]
    [Column ("FldStartTime")]
    public DateTime MyStartTime { get; set; }
    [Required]
    [Column ("FldEndTime")]
    public DateTime MyEndTime { get; set; }
    [Column("FldModificationDate")]
    [Required]
    public DateTime ModificationDate { get; set; }

这是getAllBreaks的代码

void RefreshBreakGrid()
    {
        dgvcolDate.DataPropertyName = "ModificationDate";
        dgvcolstarttime.DataPropertyName = "MyStartTime";
        dgvcolendtime.DataPropertyName = "MyEndTime";

        dgvcolemployee.DataSource = Employee.GetAllEmployee();
        dgvcolemployee.DisplayMember = "MyName";
        dgvcolemployee.ValueMember = "MyKeyId";
        dgvcolemployee.DataPropertyName = "Employee";


        dgvcolmachine.DataSource = Machine.GetAllMachine();
        dgvcolmachine.DisplayMember = "MyName";
        dgvcolmachine.ValueMember = "MyKeyId";
        dgvcolmachine.DataPropertyName = "MyName";

        dgvcolshift.DataSource = Shift.GetAllShift();
        dgvcolshift.DisplayMember = "MyName";
        dgvcolshift.ValueMember = "MyKeyId";
        dgvcolshift.DataPropertyName = "Shift";

        _Breaks=Break.GetAllBreak();
        dgvBreak.AutoGenerateColumns = false;
        dgvBreak.DataSource = _Breaks;
    }

现在当它在班次的单元格中运行时，它显示public static List<Break> GetAllBreak() { return new ContexManager().Breaks.Where(c => c.MyKeyId != 0).Include(c => c.Machine).Include(c => c.Employee).Include(c => c.Shift).ToList(); }用于机器，员工如班次我必须为此做些什么？

它通过覆盖每个类

的toString方法来解决
