[英]ASP.Net MVC How to pass url parameters using Html.RenderAction to a ChildAction
我認為這將是直截了當的,但我設法把它搞砸了。 如果我想將URL參數傳遞給另一個操作,我是否必須為此創建新路由?
調節器
[ChildActionOnly]
public ActionResult ContentSection(string sectionAlias, string mvcController, string mvcAction = null)
視圖
@Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"})
錯誤
CS1502: The best overloaded method match for 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' has some invalid arguments
這里的問題是
@Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"})
相當於
<%= Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"}) %>
在ViewEngine
(也是一個Response.Write
)。 由於RenderAction
返回void
,因此無法Response.Write
它。 你想要做的是:
@{
Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"});
}
@{ }
語法表示Razor視圖引擎中的代碼塊,它等同於以下ViewEngine
:
<% Html.RenderAction("ContentSection", "Portal", new {sectionAlias = "TermsAndConditions", mvcController = "Portal", mvcAction = "ChoosePayment"}); %>
簡短的回答是:使用@ Html.Action()。
@Html.Action("ContentSection", "Portal", new {sectionAlias = "Terms", ...})
Nathan Anderson已經給出了很長的答案 。
這個答案的PS Credit真的歸於詹姆斯·奈爾(James Nail),后者在內森的回答中將其作為評論發表,但我發現它非常簡單和有價值,我認為應該是個人答案。
