呼叫UrlHelper在ASP.NET MVC模型 [英] Call UrlHelper in models in ASP.NET MVC

问题描述

我需要生成在ASP.NET MVC模型的一些网址。我想打电话像UrlHelper.Action（），它使用的路由生成URL。我不介意填补空白平常一样，主机名，计划等。

I need to generate some URLs in a model in ASP.NET MVC. I'd like to call something like UrlHelper.Action() which uses the routes to generate the URL. I don't mind filling the usual blanks, like the hostname, scheme and so on.

有没有我可以调用为任何方法？有没有一种方法来构建UrlHelper？

Is there any method I can call for that? Is there a way to construct an UrlHelper?

推荐答案

我喜欢奥马尔的回答，但是，这不是为我工作。只是为了记录这是我现在使用的解决方案：

I like Omar's answer but that's not working for me. Just for the record this is the solution I'm using now:

var httpContext = HttpContext.Current;

if (httpContext == null) {
  var request = new HttpRequest("/", "http://example.com", "");
  var response = new HttpResponse(new StringWriter());
  httpContext = new HttpContext(request, response);
}

var httpContextBase = new HttpContextWrapper(httpContext);
var routeData = new RouteData();
var requestContext = new RequestContext(httpContextBase, routeData);

return new UrlHelper(requestContext);
