C#ASP.NETMVC：提交按鈕后不會存盤資料-有解無憂

我正在學習 C# 和 ASP.NET MVC，我需要這方面的幫助。

單擊提交按鈕“Sacuvaj”中的文本@html.EditorFor不會改變后，我需要將“plata”中的資料放入該文本框中，@ViewBag.Message作業正常，單擊“Sacuvaj”按鈕后收到訊息，資料良好，但在編輯器中獲勝不要輸入，我需要“fondCasova”中的數字與“183”同為 * 并將結果發布為“brutoPlata”，謝謝。

這是控制器代碼：

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using ObracunZarade.Models;
using System.Linq;
using System.Web.Mvc;

namespace ObracunZarade.Controllers
{
    public class obracunController : Controller
    {
        private SqlConnection conn;

        private void connection()
        {
            string constr = "data source=desktop-kmn8om7\\mssqlserver98;initial catalog=obracunBaza;integrated security=True;";
            conn = new SqlConnection(constr);
        }

        public ActionResult dodajObracun()
        {
            return View();
        }
        
        [HttpPost]
        public ActionResult dodajObracun(obracunModel obm, string btn)
        {
            if(btn == "Izracunaj")
            {
                ViewBag.Message = "KLIKNUO SI IZRACUNAJ";
                return View();
            }

            try
            {
                if(ModelState.IsValid)
                {
                    /*if(dodajObracunBool(obm))
                    {
                        ViewBag.Message = "Obracun je upisan u bazu";
                    }*/
                }
 
                decimal plata = obm.fondCasova * 183;
                obm.osnNetoZarada = plata;
                
                obm.netoOsnovica = 100;
                ViewBag.Message = plata;
                obm.BrutoPlata = plata;
 
               return View();
            }
            catch
            {
                ViewBag.Message = "Obracun nije upisan u bazu";
                return View();
            }
        }

        [HttpPut]
        public bool dodajObracunBool(obracunModel obm)
        {
            //if () 
            connection();

            SqlCommand c = new SqlCommand("SQLQuery6", conn);
            c.CommandType = CommandType.StoredProcedure;

            c.Parameters.AddWithValue("@Ime", obm.Ime);
            c.Parameters.AddWithValue("@Prezime", obm.Prezime);
            c.Parameters.AddWithValue("@Adresa", obm.Adresa);
            c.Parameters.AddWithValue("@fondCasova", obm.fondCasova);
            c.Parameters.AddWithValue("@osnNetoZarada", obm.osnNetoZarada);
            c.Parameters.AddWithValue("@iznPoreza", obm.iznPoreza);
            c.Parameters.AddWithValue("@iznDoprinosaPIO", obm.iznDoprinosaPIO);
            c.Parameters.AddWithValue("@iznDoprinosaZaZdrav", obm.iznDoprinosaZaZdrav);
            c.Parameters.AddWithValue("@iznDoprinosaZaNezap", obm.iznDoprinosaZaNezap);
            c.Parameters.AddWithValue("@netoOsnovica", obm.netoOsnovica);
           // c.Parameters.AddWithValue("@BrutoPlata", obm.BrutoPlata);

            conn.Open();
            int i = c.ExecuteNonQuery();
            conn.Close();

            if (i >= 1)
            {
                return true;
            }
            else
            {
                return false;
            }
        }
    }
}

這是模型類：

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace ObracunZarade.Models
{
    public class obracunModel
    {
        public int obracunID { get; set; }
        
        public string Ime { get; set; }
        public string Prezime { get; set; }
        public string Adresa { get; set; }

        public int fondCasova { get; set; }

        public decimal osnNetoZarada { get; set; }
        public decimal iznPoreza { get; set; }
        public decimal iznDoprinosaPIO { get; set; }
        public decimal iznDoprinosaZaZdrav { get; set; }
        public decimal iznDoprinosaZaNezap { get; set; }
        public decimal netoOsnovica { get; set; }
        public decimal BrutoPlata { get; set; }
    }
}

uj5u.com熱心網友回復：

你所有的return View()陳述都是空的；您沒有將模型（obm）發送回視圖。Young Shung 有說過你應該像這樣通過模型嗎？

ViewBag.Message = plata;              
obm.BrutoPlata = plata;                      
return View(obm);                     
enter code here
