在完全信任程序集列表沙箱应用程序中找到空的强名称 [英] A null strongname was found in the full trust assembly list sandbox application

问题描述

无论何时运行，我都在.net中开发了沙箱应用程序

错误"  

I had develop the sandbox application in .net.whenever run the application i get the 

error "  

"

在行上发生错误

AppDomain newDomain = AppDomain.CreateDomain("Sandbox", null, adSetup, permSet, fullTrustAssembly);

我的应用程序:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;  
using System.Threading.Tasks;

namespace UntrustedCode
{
    public class UntrustedClass 
    {
        public static bool IsFibonacci(int number)
        {
            File.ReadAllText("C:\\TEMP\\file.txt");
            return false;
        } 
    }
}

在沙箱中运行应用程序:

<pre>using System;
using System.Collections.Generic;

using System.Threading.Tasks;

using System.Security;
using System.Security.Policy;

using System.Reflection;
using System.Runtime.Remoting;  

namespace Sandboxer 
{
    class Sandboxer : MarshalByRefObject
    {
        const string pathToUntrusted = @"C:\Users\Amma\Documents\visual studio 2012\Projects\UntrustedCode\UntrustedCode\bin\Debug";
        const string untrustedAssembly = "UntrustedCode";
        const string untrustedClass = "UntrustedCode.UntrustedClass";
        const string entryPoint = "IsFibonacci";
        private static Object[] parameters = { 11 };  
        static void Main(string[] args)
        {
            
            AppDomainSetup adSetup = new AppDomainSetup();
            adSetup.ApplicationBase = Path.GetFullPath(pathToUntrusted);

            
            PermissionSet permSet = new PermissionSet(PermissionState.None);
            permSet.AddPermission(new SecurityPermission(SecurityPermissionFlag.Execution));
            
            StrongName fullTrustAssembly = typeof(Sandboxer).Assembly.Evidence.GetHostEvidence<StrongName>();

  
            AppDomain newDomain = AppDomain.CreateDomain("Sandbox", null, adSetup, permSet, fullTrustAssembly);

            
            ObjectHandle handle = Activator.CreateInstanceFrom(
                newDomain, typeof(Sandboxer).Assembly.ManifestModule.FullyQualifiedName,
                typeof(Sandboxer).FullName
                );
           
            Sandboxer newDomainInstance = (Sandboxer)handle.Unwrap();
            newDomainInstance.ExecuteUntrustedCode(untrustedAssembly, untrustedClass, entryPoint, parameters);  
        }
        public void ExecuteUntrustedCode(string assemblyName, string typeName, string entryPoint, Object[] parameters)
        {
            
            MethodInfo target = Assembly.Load(assemblyName).GetType(typeName).GetMethod(entryPoint);
            try
            {
                
                bool retVal = (bool)target.Invoke(null, parameters);
            }
            catch (Exception ex)
            {
               
                (new PermissionSet(PermissionState.Unrestricted)).Assert();
                Console.WriteLine("SecurityException caught:\n{0}", ex.ToString());
                CodeAccessPermission.RevertAssert();
                Console.ReadLine();
            }
        }  








    }
}

为什么会出现错误.

我签署了带有强力名称的程序集，该代码在代码中显得很重要

  StrongName fullTrustAssembly = typeof(Sandboxer).Assembly.Evidence.GetHostEvidence<StrongName>();

请帮助我.
