c# - DataBinding 不包含属性

Question

请帮忙，因为我是 C# 的新手

我面临以下错误

“DataBinding：‘Sherserve.CustomTypeLayer.EmployeeLeave’不包含名为‘empId’的属性”

这是我的代码：

protected void Button1_Click(object sender, EventArgs e)
{
    LMSManager leavestatus = new LMSManager();
    int emplid = Convert.ToInt32(Session["EmployeeID"]);
    List<EmployeeLeave> leaverecord = leavestatus.GetLeaveRecord(emplid);

    GridView1.DataSource = leaverecord;
    GridView1.DataBind();
}

这是 EmployeeLeave ：

public class EmployeeLeave
{
    public LeaveReason LeaveType { get; set; }
    public int EmployeeId { get; set; }
    public DateTime DateFrom { get; set; }
    public DateTime DateTo { get; set; }
    public string Reason { get; set; }
}

这是 aspx ：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" AllowPaging="True"
  PageSize="3" OnPageIndexChanging="GridView1_PageIndexchanging" CellPadding="4"
  ForeColor="#333333" Height="16px"

看起来您的数据绑定指的是实际调用empId的字段。EmployeeLeaveEmployeeId

尝试改变

<ItemTemplate>
    <asp:Label ID="lblEmpId" runat="server" Text='<%#Eval("empId")%>'></asp:Label>
</ItemTemplate>

至

<ItemTemplate>
    <asp:Label ID="lblEmpId" runat="server" Text='<%#Eval("EmployeeId")%>'></asp:Label>
</ItemTemplate>
