How to pass value from one action to another action having same controller
提问by Abhay Singh
Hi I am developing an application in MVC3. and i am stuck at one place. Everytime when control goes to IIndex1action its argument value has become 0. But it should be same as value in IIndexaction argument. I have used session, ViewBag, ViewData but my problem is remains. Please suggest me.
嗨，我正在 MVC3 中开发一个应用程序。我被困在一个地方。每次控制执行IIndex1动作时，其参数值都变为 0。但它应该与IIndex动作参数中的值相同。我使用过 session、ViewBag、ViewData，但我的问题仍然存在。请建议我。
public ActionResult GetMDN(string msisdn)
{
number = msisdn.Substring(0, msisdn.IndexOf('$'));
if (number.ToLower() != "unknown" && number.Length == 12)
{
number = number.Remove(0, 2);
}
Session["msdresponse"] = number;
Session["moptr"] = msisdn.Substring(msisdn.LastIndexOf('$') + 1);
number = msisdn;
int sngid=int.Parse(ViewData["isongid"].ToString());
return RedirectToAction("IIndex1", new { iid = sngid });
}
public ActionResult IIndex(int id)
{
ViewBag.isongid = id;
ViewData["isongid"] = id;
Response.Redirect("http:XXXXXXXXXXXXXXXX");
return RedirectToAction("GetMDN");
}
public ActionResult IIndex1(int iid)
{
}

You can use TempData.You can pass every types of data between to action, whether they are in same controller or not. Your code should be something like it:
您可以使用 TempData。您可以在操作之间传递各种类型的数据，无论它们是否在同一个控制器中。你的代码应该是这样的：
public ActionResult GetMDN(string msisdn)
{
int sngid=10;
TempData["ID"] = sngid;
return RedirectToAction("IIndex");
}
public ActionResult IIndex()
{
int id = Convert.ToInt32(TempData["ID"]);// id will be 10;
}

Use TempData instead of ViewData/ViewBag to store data that should persist after redirect. ViewData/ViewBag allow to pass value from controller to view.
使用 TempData 而不是 ViewData/ViewBag 来存储重定向后应该保留的数据。ViewData/ViewBag 允许将值从控制器传递到视图。
