MVC3 Razor视图获取System.InvalidOperationException错误

Question

MVC3 Razor我正在编辑/更新应用程序，但执行视图获取错误

  

异常详细信息：System.InvalidOperationException：模型项   传入字典的类型   ＆＃39; PayrollApplication.Models.PeopleService＆＃39;，但是这本词典   需要类型的模型项   ＆＃39; System.Collections.Generic.IEnumerable`1 [PayrollApplication.Models.tbl_PeopleInfo]＆＃39;

控制器代码编辑方法

＆＃13;

＆＃13;

  [HttpGet]
    public ActionResult EditView(PeopleService model, int id)
    {           
        PeopleService updatemodel = new PeopleService();
        SqlConnection cn = new SqlConnection(conStr);
        SqlCommand cmd = new SqlCommand("Select PersonId,Name ,Surname,Email ,Birthdate,Children  From tbl_PeopleInfo Where PersonId=" + id, cn);
        cn.Open();
        SqlDataReader dr = cmd.ExecuteReader();
        DataTable Dt = new DataTable();
        //Dt.Load(dr);


        if (dr.Read())
        {

            updatemodel.PersonId = Convert.ToInt32(dr["PersonId"].ToString().Trim());
            updatemodel.Name = dr["Name"].ToString().Trim();
            updatemodel.Surname = dr["Surname"].ToString().Trim();
            updatemodel.Email = dr["Email"].ToString().Trim();
            updatemodel.Birthdate = Convert.ToDateTime(dr["Birthdate"].ToString().Trim());
            updatemodel.Children = Convert.ToInt32(dr["Children"].ToString().Trim());
            updatemodel.PassWord = "";
            updatemodel.UserName = "";
          
        }
        else
        {
            dr.Close();
        }
        dr.Close();
        cn.Close();

        return View(updatemodel);
    }
    [HttpPost]
    public ActionResult EditView(PayrollApplication.Models.PeopleService updatemodel, FormCollection collection, int id)
    {

        if (ModelState.IsValid)
        {
            int _records = updatemodel.Update(updatemodel.Name, updatemodel.Surname, updatemodel.Email, updatemodel.Birthdate, updatemodel.Children, updatemodel.PersonId);
            if (_records > 0)
            {
                return RedirectToAction("EmployeeMaster", "Home");
            }
            else
            {
