Question

在MVC5中，我希望我的SetCulture操作具有行为，这样在完成后，它会返回到调用它的原始操作 - 包括参数。

对于没有参数的动作来说，这似乎很容易。视图中的Html.ActionLink：

@Html.ActionLink("中文 (臺灣)", "SetCulture", "Home", routeValues: new { culture = "zh-tw", currentController = ViewContext.RouteData.Values["controller"], currentAction = ViewContext.RouteData.Values["action"] }, htmlAttributes: new { id = "zh-tw" })

然后是控制器：

public ActionResult SetCulture(string culture, string currentController, string currentAction)
{
    // Validate input
    culture = CultureHelper.GetImplementedCulture(culture);
    // Save culture in a cookie
    HttpCookie cookie = Request.Cookies["_culture"];
    if (cookie != null)
        cookie.Value = culture;   // update cookie value
    else
    {
        cookie = new HttpCookie("_culture");
        cookie.Value = culture;
        cookie.Expires = DateTime.Now.AddYears(1);
    }
    Response.Cookies.Add(cookie);
    return RedirectToAction(currentAction, currentController);
}

这很好用。但是，当它被调用的动作是，例如：public ActionResult ClassTimeTable(DateTime date)

时，我感到难过。

现在，我知道将SetCulture放回主页很容易。但是如果可以的话，我想解决这个问题。

只需将URL作为参数传递，然后重定向回该网址：

@Html.ActionLink("中文 (臺灣)", "SetCulture", "Home", routeValues: new { culture = "zh-tw", url = Request.Url.ToString() }, htmlAttributes: new { id = "zh-tw" })

然后你的方法是：

public ActionResult SetCulture(string culture, string url)
{
    // Validate input
    culture = CultureHelper.GetImplementedCulture(culture);
    // Save culture in a cookie
    HttpCookie cookie = Request.Cookies["_culture"];
    if (cookie != null)
        cookie.Value = culture;   // update cookie value
    else
    {
        cookie = new HttpCookie("_culture");
        cookie.Value = culture;
        cookie.Expires = DateTime.Now.AddYears(1);
    }
    Response.Cookies.Add(cookie);
    return Redirect(url);
}
