C# & ASP.NET MVC：将参数从一个 controller 传递到另一个添加/保存

Question

I'm using C# and ASP.NET MVC framework i have two DbContext UserEntities and DB2TableEntities and i need to pass some parameters to one controler to another and save: I already have connected both databases through an ADO.NET Entity Data Model. 基本上我需要收集一些存储在 SQL 服务器中的信息，然后我需要将这些数据插入到不同的表中。

我试图将两个参数（user_id 和 group_id）从一个 controller 传递到另一个并添加/保存，使用 TempData 字典，但在这种情况下，我需要传递和保存/添加不需要在视图中显示仅用于存储数据,

只是一个例子

namespace UserRequestsPortal.Models.UserRequests
{
    using System;
    using System.Data.Entity;
    using System.Data.Entity.Infrastructure;
    
    public partial class UserEntities : DbContext
    {
        public UserEntities()
            : base("name=UserEntities")
        {
        }
    
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            throw new UnintentionalCodeFirstException();
        }
    
        public DbSet<UserRequests> UserRequests { get; set; }
    }
}




namespace UserRequestsPortal.Models.DB2
{
    using System;
    using System.Data.Entity;
    using System.Data.Entity.Infrastructure;
  
    public partial class DB2TableEntities : DbContext
    {
        public DB2TableEntities()
            : base("name=DB2TableEntities")
        {
        }
    
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            throw new UnintentionalCodeFirstException();
        }
    
        public DbSet<Table01> Table01 { get; set; }
        public DbSet<Table02> Table02 { get; set; }
        public DbSet<Table03> Table03 { get; set; }
    }
}

//   UserRequests db = new UserRequests();

        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult CreateAccess([Bind(Include = "userid,name,lastname,description,phone,created ")] UserRequests userRequests)
        {
            string userid = userRequests.userid;
             string description = userRequests.description;
        
            if (ModelState.IsValid )
            {
               db.UserRequests.Add(userRequests);
               db.SaveChanges();
              return RedirectToAction("Index");
            }

            if (userRequests.created == true)
            {
             
               Table01 db = new Table01() {

                user_id = userRequests.userid,
                group_id = userRequests.description,
                lastchange =  DateTime.Now,
                changeby = "Tom",
                versioncontrol = 0
                // i dont know if is possible to add and save in this block

                };
                TempData["Table01_data"] = db;
                return RedirectToAction("Create", "DB2Controller");
            }

            return View(userRequests);
        }

        // POST: Table01/Create

        //   DB2TableEntities db = new DB2TableEntities();

        [HttpPost]
        [ValidateAntiForgeryToken]
         public ActionResult Create([Bind(Include = "user_id,group_id,lastchange,changeby,versioncontrol")] Table01 table01)
       
        {
            {
               
                Table01 db = TempData["Table01_data"] as Table01;

                if (ModelState.IsValid)
                {
                     db.Table01.Add(table01);
                    db.SaveChanges();
                    return RedirectToAction("Index");
                }

               
                return View();
            }
        }

如果有人可以给我任何提示，我将不胜感激。 此致
