Bll:

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using TESTBll.EFModel;

namespace TESTBll.Bll
{
public class Newtable
{
EFEntities ctx = new EFEntities();
public List<NEWTABLE> GetList()
{
return ctx.NEWTABLE.ToList<NEWTABLE>();
}
public NEWTABLE GetModel(string id)
{
return ctx.NEWTABLE.Where(b => b.ID == id).FirstOrDefault();
}
public void Add(NEWTABLE newvalue)
{
ctx.NEWTABLE.Add(newvalue);
ctx.SaveChanges();
}
public void updata(NEWTABLE newvalue)
{

ctx.Set<NEWTABLE>().Attach(newvalue);
ctx.Entry(newvalue).State = EntityState.Modified;
ctx.SaveChanges();
}
public void Delete(string id)
{
string sql = "delete NEWTABLE where id = " + id + "";
ctx.Database.ExecuteSqlCommand(sql);
}
}
}

点击保存没反应，设置断点进Edit中的try，到了updata第一句进Edit中try就退出进catch了。我觉得是这个方法有问题。这是照着别人的例子做的，updata方法我不会写，不知道怎么接收用户输入的值，麻烦帮我更正。
