c# – 将模型从一个动作传递到同一个控制器中的另一个动作

我试图通过我的模型列表< Models.Statement> statementList从一个动作到另一个动作,但我在第二个控制器中收到空值.请在这里建议有什么问题.甚至试过：

return RedirectToAction("WriteInTemplate",new { statementList = statementList });

请帮忙.

public ActionResult SendPdfStatement(string InvoiceNumber)
    {
        try
        {
            InvoiceNumber = InvoiceNumber.Trim();

            ObjectParameter[] parameters = new ObjectParameter[1];
            parameters[0] = new ObjectParameter("InvoiceNumber",InvoiceNumber);

            List<Models.Statement> statementList = new List<Models.Statement>();
            statementList = _db.ExecuteFunction<Models.Statement>("uspInvoiceStatement",parameters).ToList<Models.Statement>();

            //WriteInTemplate(statementList);
            return RedirectToAction("WriteInTemplate",statementList );

        }
        catch (Exception e)
        {
            InvoiceSearchTool.Models.udtExceptionTable exception = new udtExceptionTable();
            exception.MethodName = "SendPdfStatement";
            exception.Exception = e.ToString();
            exception.Date = DateTime.Now;
            DYNAMICS_EXTEntities db = new DYNAMICS_EXTEntities();
            db.AddToudtExceptionTables(exception);
            db.SaveChanges();  
            return View("Error");
        }
    }

    public ActionResult WriteInTemplate(List<Models.Statement> statementList)
    {
        try
        {
            string invoiceNumber = statementList.FirstOrDefault().Invoice.ToString().Trim();
        ...................snip..........


            return RedirectToAction("CreateMessageWithAttachment","email",invoiceNumber); 
        }
        catch (Exception e)
        {
            InvoiceSearchTool.Models.udtExceptionTable exception = new udtExceptionTable();
            exception.MethodName = "WriteInTemplate";
            exception.Exception = e.ToString();
            exception.Date = DateTime.Now;
            DYNAMICS_EXTEntities db = new DYNAMICS_EXTEntities();
            db.AddToudtExceptionTables(exception);
            db.SaveChanges();

            return View("Error");
        }

    }

解决方法

请看看 here to pass your Model

你没有传递“statementList”,而是传递新的{statementList = statementList}只是传递模型,你应该没问题.

return RedirectToAction("WriteInTemplate",statementList);
