AppDomain.CreateInstanceAndUnwrap 내가 아주 간단한 클래스 CompiledFunction (MarshalByRefObject에서)가

Question

웹 사이트에서 작동하지 않습니다 - 나는 이것은 콘솔 응용 프로그램에서 잘 작동 그래서

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); 

같은 새 도메인이의 인스턴스를 만들려고 ,하지만 ASP .NET MVC 응용 프로그램에서 다음과 같은 예외가 발생합니다 - 왜이 웹 응용 프로그램에서 작동하지 않는지에 대한 제안을 제공 할 수 있습니까? 내가 지나가는 오전 T 매개 변수는 제대로 새 도메인의 웹 프로젝트를위한 어셈블리 또는 설정 잘못 ApplicationBase를 Ems.Scripting (가능성)을 복사하지 않았다처럼

Answer 1

문제는 Assembly.Code베이스가 file : /// {나머지 경로}로 시작되었습니다. Path.GetDirectoryName을 이러한 경로에 사용하면 file : ///을 단일 슬래시로 바꿉니다. 그래서 당신은 로컬 경로는 경로가 올바른지, 그리고 DLL이 그 경로에

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

이 보이는 System.Decimal입니다.

Path.GetDirectoryName 호출은 ApplicationBase 속성을 계산할 때 의심 스럽습니다.
