我以为这是直截了当的，但我设法弄清楚一些如何。如果我想将URL参数传递给另一个操作，那么我必须为此创建一个新的路由？
控制器
[ChildActionOnly]
public ActionResult ContentSection(string sectionAlias,string mvcController,string mvcAction = null)
视图
@Html.RenderAction("ContentSection","Portal",new {sectionAlias = "TermsAndConditions",mvcController = "Portal",mvcAction = "ChoosePayment"})
CS1502: The best overloaded method match for 'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' has some invalid arguments
解决方法
这里的问题是
@Html.RenderAction("ContentSection",mvcAction = "ChoosePayment"})
相当于
<%= Html.RenderAction("ContentSection",mvcAction = "ChoosePayment"}) %>
在Webforms ViewEngine中(这也是Response.Write的一样)。由于RenderAction返回void，您不能Response.Write它。你想做的是这样的：
@{
Html.RenderAction("ContentSection",mvcAction = "ChoosePayment"});
}
@ {}语法表示Razor视图引擎中的一个代码块，它将等同于以下Webforms ViewEngine：
<% Html.RenderAction("ContentSection",mvcAction = "ChoosePayment"}); %>
