asp.net-mvc – 仅从路由数据生成URL

我正在尝试在ASP.NET MVC中做一些简单的事情：

RouteValuesDictionary routeValues = GetMyRouteData();
var url = new UrlHelper(Html.ViewContext.RequestContext);
return url.RouteUrl(routeValues);

问题在于,无论我做什么,url都包含来自当前请求上下文的路由数据.我想基于GetMyRouteData()的路由值生成一个URL.

谢谢

解决方法

The problem is that no matter what I do,the url includes route data
from the current request context

这是设计的.您必须显式设置原始请求中存在的路由值,并且您不希望在生成的URL中为null：

var routeValues = GetMyRouteData();
    // remove values that you want to exclude from the resulting url
    // by setting their values to null
    routeValues["id"] = null;
    var url = new UrlHelper(Html.ViewContext.RequestContext);
    return url.RouteUrl(routeValues);
