AppDomain.CreateInstanceAndUnwrapは、私は非常に単純なクラスCompiledFunction（MarshalByRefObjectを）を持っているウェブサイト

Question

で働いていない - 私はそう

var appDomainSetup = new AppDomainSetup(); 
appDomainSetup.ApplicationBase = Path.GetDirectoryName(typeof(CompilerService).Assembly.CodeBase); 
var evidence = AppDomain.CurrentDomain.Evidence; 
SandboxDomain = AppDomain.CreateDomain("Sandbox", evidence, appDomainSetup); 

CompiledFunction<T> result = (CompiledFunction<T>)SandboxDomain.CreateInstanceAndUnwrap(
    assemblyName: typeof(CompiledFunction<T>).Assembly.GetName().Name, 
    typeName: typeof(CompiledFunction<T>).FullName); 

これは、コンソールアプリケーションで正常に動作するように、新しいドメインでこれのインスタンスを作成しようしかし、ASP .NET MVCアプリケーションでは、次のような例外があります。なぜ、これがWebアプリケーションで動作しないのか、誰にでも示唆を提供できますか？私は合格していますTパラメータを使用すると、正しく新しいドメインのWebプロジェクトのためのアセンブリまたは設定が間違っApplicationBaseをEms.Scripting（可能性が高い）をコピーしていなかったよう

Answer 1

問題は、Assembly.Codeベースがfile：/// {残りのパスここ}から始まりました。このようなパスでPath.GetDirectoryNameを使用すると、file：///が単一のスラッシュで置き換えられます。あなたは「/c:\myfolder\myfile.dll」で終わるURIがローカルパスを私に教えて取得

が

if (SandboxDomain == null) 
{ 
    var appDomainSetup = new AppDomainSetup(); 
    string appBase = typeof(CompilerService).Assembly.CodeBase; 

    //Added the following line 
    appBase = new Uri(appBase).LocalPath; 
    appDomainSetup.ApplicationBase = Path.GetDirectoryName(appBase); 
    var evidence = AppDomain.CurrentDomain.Evidence; 
    SandboxDomain = AppDomain.CreateDomain("Sandbox", evidence, appDomainSetup); 
} 

Answer 2

が見えるSystem.Decimalのです。

Path.GetDirectoryName呼び出しは、ApplicationBaseプロパティを計算する際に不審です。
