これが私の解決策です。[ExportModelStateToTempData]/[ImportModelStateFromTempData]を使用するのは私の意見では不快です。
〜/ Views / Home / Error.cshtml：
@{
ViewBag.Title = "Error";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Error</h2>
<hr/>
<div style="min-height: 400px;">
@Html.ValidationMessage("Error")
<br />
<br />
<button onclick="Error_goBack()" class="k-button">Go Back</button>
<script>
function Error_goBack() {
window.history.back()
}
</script>
</div>
〜/ Controllers / HomeController.sc：
public class HomeController : BaseController
{
public ActionResult Index()
{
return View();
}
public ActionResult Error()
{
return this.View();
}
...
}
〜/ Controllers / BaseController.sc：
public class BaseController : Controller
{
public BaseController() { }
protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
if (filterContext.Result is ViewResult)
{
if (filterContext.Controller.TempData.ContainsKey("Error"))
{
var modelState = filterContext.Controller.TempData["Error"] as ModelState;
filterContext.Controller.ViewData.ModelState.Merge(new ModelStateDictionary() { new KeyValuePair<string, ModelState>("Error", modelState) });
filterContext.Controller.TempData.Remove("Error");
}
}
if ((filterContext.Result is RedirectResult) || (filterContext.Result is RedirectToRouteResult))
{
if (filterContext.Controller.ViewData.ModelState.ContainsKey("Error"))
{
filterContext.Controller.TempData["Error"] = filterContext.Controller.ViewData.ModelState["Error"];
}
}
base.OnActionExecuted(filterContext);
}
}
〜/ Controllers / MyController.sc：
public class MyController : BaseController
{
public ActionResult Index()
{
return View();
}
public ActionResult Details(int id)
{
if (id != 5)
{
ModelState.AddModelError("Error", "Specified row does not exist.");
return RedirectToAction("Error", "Home");
}
else
{
return View("Specified row exists.");
}
}
}
私はあなたに成功したプロジェクトを望みます;-)
