如何通过RedirectToAction传递类 [英] How to pass class via RedirectToAction
本文介绍了如何通过RedirectToAction传递类的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有以下的code：
public ActionResult Index()
{
AdminPreRegUploadModel model = new AdminPreRegUploadModel()
{
SuccessCount = successAddedCount,
FailureCount = failedAddedCount,
AddedFailure = addedFailure,
AddedSuccess = addedSuccess
};
return RedirectToAction("PreRegExceUpload", new { model = model });
}
public ActionResult PreRegExceUpload(AdminPreRegUploadModel model)
{
return View(model);
}
但模型为空时，我断点preRegExcelUpload。为什么呢？
but model is null when I breakpoint on PreRegExcelUpload. Why?
推荐答案
我会建议使用 TempData的。见的http://rachelappel.com/when-to-use-viewbag-viewdata-or-tempdata-in-asp.net-mvc-3-applications关于的TempData 。
Instead of using the Session object in Evgeny Levin's answer I would suggest to use TempData. See http://rachelappel.com/when-to-use-viewbag-viewdata-or-tempdata-in-asp.net-mvc-3-applications about TempData.
您也可以通过调用收益preRegExceUpload（模型）解决这个问题$ C>你首页功能。
You could also fix this by calling return PreRegExceUpload(model); instead of return RedirectToAction(..) in you Index function.
