私はあなたと同じ問題を抱えているので、すべての検索の後、解決策が得られました
独自の WebViewPage ベースの抽象クラスを作成します (モデルのジェネリックおよび非ジェネリック)
public abstract class MyOwnViewPage<TModel> : WebViewPage<TModel> { }
public abstract class MyOwnViewPage : WebViewPage { }
次に、VirtualFile ベースのクラスまたは埋め込みビューを作成します。
class AssemblyResourceFile : VirtualFile
{
private readonly IDictionary<string, Assembly> _nameAssemblyCache;
private readonly string _assemblyPath;
private readonly string _webViewPageClassName;
public string LayoutPath { get; set; }
public string ViewStartPath { get; set; }
public AssemblyResourceFile(IDictionary<string, Assembly> nameAssemblyCache, string virtualPath) :
base(virtualPath)
{
_nameAssemblyCache = nameAssemblyCache;
_assemblyPath = VirtualPathUtility.ToAppRelative(virtualPath);
LayoutPath = "~/Views/Shared/_Layout.cshtml";
ViewStartPath = "~/Views/_ViewStart.cshtml";
_webViewPageClassName = typeofMyOwnViewPage).ToString();
}
// Please change Open method for your scenario
public override Stream Open()
{
string[] parts = _assemblyPath.Split(new[] { '/' }, 4);
string assemblyName = parts[2];
string resourceName = parts[3].Replace('/', '.');
Assembly assembly;
lock (_nameAssemblyCache)
{
if (!_nameAssemblyCache.TryGetValue(assemblyName, out assembly))
{
var assemblyPath = Path.Combine(HttpRuntime.BinDirectory, assemblyName);
assembly = Assembly.LoadFrom(assemblyPath);
_nameAssemblyCache[assemblyName] = assembly;
}
}
Stream resourceStream = null;
if (assembly != null)
{
resourceStream = assembly.GetManifestResourceStream(resourceName);
if (resourceName.EndsWith(".cshtml"))
{
//the trick is here. We must correct our embedded view
resourceStream = CorrectView(resourceName, resourceStream);
}
}
return resourceStream;
}
public Stream CorrectView(string virtualPath, Stream stream)
{
var reader = new StreamReader(stream, Encoding.UTF8);
var view = reader.ReadToEnd();
stream.Close();
var ourStream = new MemoryStream();
var writer = new StreamWriter(ourStream, Encoding.UTF8);
var modelString = "";
var modelPos = view.IndexOf("@model");
if (modelPos != -1)
{
writer.Write(view.Substring(0, modelPos));
var modelEndPos = view.IndexOfAny(new[] { '\r', '\n' }, modelPos);
modelString = view.Substring(modelPos, modelEndPos - modelPos);
view = view.Remove(0, modelEndPos);
}
writer.WriteLine("@using System.Web.Mvc");
writer.WriteLine("@using System.Web.Mvc.Ajax");
writer.WriteLine("@using System.Web.Mvc.Html");
writer.WriteLine("@using System.Web.Routing");
var basePrefix = "@inherits " + _webViewPageClassName;
if (virtualPath.ToLower().Contains("_viewstart"))
{
writer.WriteLine("@inherits System.Web.WebPages.StartPage");
}
else if (modelString == "@model object")
{
writer.WriteLine(basePrefix + "<dynamic>");
}
else if (!string.IsNullOrEmpty(modelString))
{
writer.WriteLine(basePrefix + "<" + modelString.Substring(7) + ">");
}
else
{
writer.WriteLine(basePrefix);
}
writer.Write(view);
writer.Flush();
ourStream.Position = 0;
return ourStream;
}
}
次に、VirtualPathProvider ベースのクラスを作成します (目的に合わせて変更します)。
public class AssemblyResPathProvider : VirtualPathProvider
{
private readonly Dictionary<string, Assembly> _nameAssemblyCache;
private string _layoutPath;
private string _viewstartPath;
public AssemblyResPathProvider(string layout, string viewstart)
{
_layoutPath = layout;
_viewstartPath = viewstart;
_nameAssemblyCache = new Dictionary<string, Assembly>(StringComparer.InvariantCultureIgnoreCase);
}
private bool IsAppResourcePath(string virtualPath)
{
string checkPath = VirtualPathUtility.ToAppRelative(virtualPath);
bool bres1 = checkPath.StartsWith("~/App_Resource/",
StringComparison.InvariantCultureIgnoreCase);
bool bres2 = checkPath.StartsWith("/App_Resource/",
StringComparison.InvariantCultureIgnoreCase);
//todo: fix this
if (checkPath.EndsWith("_ViewStart.cshtml"))
{
return false;
}
if (checkPath.EndsWith("_ViewStart.vbhtml"))
{
return false;
}
return ((bres1 || bres2));
}
public override bool FileExists(string virtualPath)
{
return (IsAppResourcePath(virtualPath) ||
base.FileExists(virtualPath));
}
public override VirtualFile GetFile(string virtualPath)
{
if (IsAppResourcePath(virtualPath))
{
// creating AssemblyResourceFile instance
return new AssemblyResourceFile(_nameAssemblyCache, virtualPath,_layoutPath,virtualPath);
}
return base.GetFile(virtualPath);
}
public override CacheDependency GetCacheDependency(
string virtualPath,
IEnumerable virtualPathDependencies,
DateTime utcStart)
{
if (IsAppResourcePath(virtualPath))
{
return null;
}
return base.GetCacheDependency(virtualPath,
virtualPathDependencies, utcStart);
}
}
最後に、global.asax に AssemblyResPathProvider を登録します。
string _layoutPath = "~/Views/Shared/_Layout.cshtml";
string _viewstarPath = "~/Views/_ViewStart.cshtml";
HostingEnvironment.RegisterVirtualPathProvider(new AssemblyResPathProvider(_layoutPath,_viewstarPath));
これは理想的な解決策ではありませんが、私にとってはうまく機能しています。乾杯！
