Question

我目前在尝试向数据库添加行时出现问题...这是Visual Studio 2013上的一个Windows窗体应用程序...我有一个实体文件夹，我的TargetCells表已上传...

我也尝试从我正在创建的对象中取出所有内容，然后执行第一行..这样我只使用该对象传递了1个项目，但它仍然不喜欢...所以我不要认为我的模型被打包/对象创建的方式....

我的错误：

“System.Data.Entity.DbSet<AssemblyTargets.Entities.TargetCells>.Add(AssemblyTargets.Entities.TargetCells)”的最佳重载方法匹配包含一些无效参数

在我的构造函数中:(行db.TargetCells.Add（cellModel）是我的错误发生的地方，我把星星围绕它来帮助你找到它..）

        Cell1Model cellModel = new Cell1Model
        {
            cell = 1,
            DateTime = Convert.ToDateTime(today),
            customerdemand = Convert.ToInt32(txtCusDemand.Text),
            StartTime = Convert.ToDateTime(txtTeamStart.Text),
            Break1 = Convert.ToDateTime(txtBreak1Time.Text),
            Break2 = Convert.ToDateTime(txtBreak2Time.Text),
            Break3 = Convert.ToDateTime(txtBreak3Time.Text),
            TimeforBreak1 = Convert.ToInt32(txtBreak1.Text),
            TimeforBreak2 = Convert.ToInt32(txtBreak2.Text),
            Timeforbreak3 = Convert.ToInt32(txtBreak3.Text),
            Lunch = Convert.ToDateTime(txtLunch1Time.Text),
            TimeforLunch = Convert.ToInt32(txtLunchBreak.Text)
        };


        // Add the new object to the TargetCells collection.

        ***db.TargetCells.Add(cellModel);***


        try
        {
            db.SaveChanges(cellModel);
        }
        catch (Exception)
        {
            Console.WriteLine(e);
            // Make some adjustments. 
            // ... 
            // Try again.
            db.SaveChanges();
        }

我的模特看起来像：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using AssemblyTargets.Models;
using AssemblyTargets.Entities;


namespace AssemblyTargets.Models
{
class Cell1Model
{
    public int recid { get; set; }
    public int? cell { get; set; }
    public DateTime? DateTime { get; set; }
    public int? customerdemand { get; set; }
    public DateTime? StartTime { get; set; }
    public DateTime? Break1 { get; set; }
    public int? TimeforBreak1 { get; set; }
    public DateTime? Break2 { get; set; }
    public int? TimeforBreak2 { get; set; }
    public DateTime? Break3 { get; set; }
    public int? Timeforbreak3 { get; set; }
    public DateTime? Lunch { get; set; }
    public int? TimeforLunch { get; set; }
}
}

任何想法我做错了什么？
