从一个动作过关模式，在同一个控制器的另一个行动 [英] pass model from one action to another action in same controller

问题描述

我想通过我的模型名单，LT; Models.Statement>语句列表从一个动作到另一个但我在第二控制器接收空值。请建议什么是错在这里。即使尝试：

 返回RedirectToAction（WriteInTemplate，新的{语句列表=语句列表}）;
 

请帮忙。

 公众的ActionResult SendPdfStatement（字符串InvoiceNumber）
    {
        尝试
        {
            InvoiceNumber = InvoiceNumber.Trim（）;            ObjectParameter [] =参数新ObjectParameter [1];
            参数[0] =新ObjectParameter（InvoiceNumber，InvoiceNumber）;            清单＆LT; Models.Statement＆GT;语句列表=新的List＆LT; Models.Statement＆GT;（）;
            语句列表= _db.ExecuteFunction＆LT; Models.Statement＆GT;（uspInvoiceStatement，参数）.ToList＆LT; Models.Statement＆GT;（）;            // WriteInTemplate（语句列表）;
            返回RedirectToAction（WriteInTemplate，语句列表）;        }
        赶上（例外五）
        {
            InvoiceSearchTool.Models.udtExceptionTable例外=新udtExceptionTable（）;
            exception.MethodName =SendPdfStatement;
            exception.Exception = e.ToString（）;
            exception.Date = DateTime.Now;
            DYNAMICS_EXTEntities DB =新DYNAMICS_EXTEntities（）;
            db.AddToudtExceptionTables（例外）;
            db.SaveChanges（）;
            返回视图（错误）;
        }
    }    公众的ActionResult WriteInTemplate（列表＆LT; Models.Statement＆GT;语句列表）
    {
        尝试
        {
            。字符串invoiceNumber = statementList.FirstOrDefault（）Invoice.ToString（）修剪（）;
        ...................剪断..........
            返回RedirectToAction（CreateMessageWithAttachment，电子邮件，invoiceNumber）;
        }
        赶上（例外五）
        {
            InvoiceSearchTool.Models.udtExceptionTable例外=新udtExceptionTable（）;
            exception.MethodName =WriteInTemplate;

解决方案

请看看<一个href=\"http://stackoverflow.com/questions/18963704/passing-model-through-redirectaction-is-null#18963758\">here通过模型

你不及格语句列表，而是要传递新的{语句列表=语句列表}只是通过模型，你应该罚款。

 返回RedirectToAction（WriteInTemplate，语句列表）;
 

由中美答案

I am trying to pass my model List< Models.Statement > statementList from one action to another but i am receiving null value in the 2nd controller. Please suggest what is wrong here. Even tried with:

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

Please help.

    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");
        }

    }

解决方案

Please take a look here to pass your Model

you are not passing "statementList" , instead you are passing new { statementList= statementList} just pass the model and you should be fine .

return RedirectToAction("WriteInTemplate", statementList);
