ASP.NET MVC使用的控制器或MVC应用程序上下文之外查看 [英] ASP.NET MVC Use Controller or View outside of the MVC application context
问题描述
您好，我创建一个小的网页，让我们的用户在我们的数据库中进行搜索的界面。
本网站必须提供2 web服务功能，搜索（字符串搜索字符串）和GetAccountInfoByInitials（字符串缩写）
我想用我的控制器，要做到这一点，但我不能找出如何我可以得到HTML出的ViewResult的。
我已经tryed以下，但result.ToString（）只给我字符串System.Web.Mvc.ViewResult
公共类SearchService：ISearchService{私人只读ServiceHandlerController _controller;
公共SearchService（）
{
_controller =新ServiceHandlerController（）;
}公共字符串搜索（字符串搜索字符串）
{
VAR的结果= _controller.Search（搜索字符串）;
返回result.ToString（）;
}公共字符串GetAccountInfoByInitials（字符串缩写）
{
VAR的结果= _controller.Search（英文缩写）的ToString（）;
返回结果;
}}
这是一个问题的答案我张贴类似于此：

} 公共静态AspHost SetupFakeHttpContext（字符串physicalDir，串virtualDir）

字符串呈现= host.ViewToString（〜/查看/ MyView.aspx，新的字典＆LT;字符串对象＆gt;（可视数据），viewData.Model）;
Hello i am creating a small webpage that give our users an interface to search in our database.
This website must supply 2 webservice functions, Search(string searchString) and GetAccountInfoByInitials(string initials)
I would like to use my controllers to do this, but i can not find out how i can get the html out of a ViewResult.
I have tryed the following, but the result.ToString() only give me the string "System.Web.Mvc.ViewResult"
public class SearchService : ISearchService
{
private readonly ServiceHandlerController _controller;
public SearchService()
{
_controller = new ServiceHandlerController();
}
public string Search(string searchString)
{
var result = _controller.Search(searchString);
return result.ToString();
}
public string GetAccountInfoByInitials(string initials)
{
var result = _controller.Search(initials).ToString();
return result;
}
}
This is an answer to a question I posted similar to this one: http://stackoverflow.com/questions/3702526/is-there-a-way-to-process-an-mvc-view-aspx-file-from-a-non-web-application
public class AspHost : MarshalByRefObject
{
public string _VirtualDir;
public string _PhysicalDir;
public string ViewToString<T>(string aspx, Dictionary<string, object> viewData, T model)
{
StringBuilder sb = new StringBuilder();
using (StringWriter sw = new StringWriter(sb))
{
using (HtmlTextWriter tw = new HtmlTextWriter(sw))
{
var workerRequest = new SimpleWorkerRequest(aspx, "", tw);
HttpContext.Current = new HttpContext(workerRequest);
ViewDataDictionary<T> viewDataDictionary = new ViewDataDictionary<T>(model);
foreach (KeyValuePair<string, object> pair in viewData)
{
viewDataDictionary.Add(pair.Key, pair.Value);
}
object view = BuildManager.CreateInstanceFromVirtualPath(aspx, typeof(object));
ViewPage viewPage = view as ViewPage;
if (viewPage != null)
{
viewPage.ViewData = viewDataDictionary;
}
else
{
ViewUserControl viewUserControl = view as ViewUserControl;
if (viewUserControl != null)
{
viewPage = new ViewPage();
viewPage.Controls.Add(viewUserControl);
}
}
if (viewPage != null)
{
HttpContext.Current.Server.Execute(viewPage, tw, true);
return sb.ToString();
}
throw new InvalidOperationException();
}
}
}
public static AspHost SetupFakeHttpContext(string physicalDir, string virtualDir)
{
return (AspHost)ApplicationHost.CreateApplicationHost(
typeof(AspHost), virtualDir, physicalDir);
}
}
Then, to render a file:
var host = AspHost.SetupFakeHttpContext("Path/To/Your/MvcApplication", "/");
var viewData = new ViewDataDictionary<SomeModelType>(){ Model = myModel };
String rendered = host.ViewToString("~/Views/MyView.aspx", new Dictionary<string, object>(viewData), viewData.Model);
