これは、私が投稿した次のような質問に対する回答です:
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);
}
}
次に、ファイルをレンダリングするには:
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);
