c# – 受限制的权限AppDomain Grant Set问题

这适用于我们的开发计算机和测试服务器(Windows 2008 IIS7 x64 .NET 4).但是在我们的生产服务器(相同规范)上,它给出了错误：

“加载此程序集将从其他实例生成不同的授权集.(HRESULT异常：0x80131401)”

这是代码： –

public static SandboxContext Create(string pathToUntrusted,List<Assembly> references)
    {
        AppDomainSetup adSetup = new AppDomainSetup();
        adSetup.ShadowCopyFiles = "true";
        var dir = new DirectoryInfo(pathToUntrusted);
        String tempPath = Path.Combine(Path.GetTempPath(),dir.Name + "_shadow");            
        adSetup.CachePath = tempPath;


        // Our sandbox needs access to this assembly.
        string AccessPath = Path.Combine(System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath,"binCommonInterfaces.WebPages.dll");
        System.IO.File.Copy(AccessPath,Path.Combine(pathToUntrusted,"CommonInterfaces.WebPages.dll"),true);
        var baseDir = Path.GetFullPath(pathToUntrusted);
        adSetup.ApplicationBase = baseDir;
        adSetup.PrivateBinPath = baseDir;

        adSetup.PartialTrustVisibleAssemblies =
            new string[] { 
                typeof(System.Web.WebPageTraceListener).Assembly.FullName,typeof(System.Web.Razor.RazorEngineHost).Assembly.FullName};

        //Setting the permissions for the AppDomain. We give the permission to execute and to 
        //read/discover the location where the untrusted code is loaded.
        PermissionSet permSet = new PermissionSet(PermissionState.None);
        permSet.AddPermission(new SecurityPermission(SecurityPermissionFlag.Execution));

        //We want the sandboxer assembly's strong name,so that we can add it to the full trust list.
        StrongName fullTrustAssembly = typeof(Sandboxer).Assembly.Evidence.GetHostEvidence<StrongName>();

        Evidence evidence = new Evidence();

        //Now we have everything we need to create the AppDomain,so let's create it.
        AppDomain newDomain = AppDomain.CreateDomain("Sandbox",evidence,adSetup,permSet,fullTrustAssembly);

        ObjectHandle handle = Activator.CreateInstanceFrom(
            newDomain,typeof(Sandboxer).Assembly.ManifestModule.FullyQualifiedName,typeof(Sandboxer).FullName
            );
        //Unwrap the new domain instance into a reference in this domain and use it to execute the 
        //untrusted code.
        var newDomainInstance = (Sandboxer)handle.Unwrap();
        return new SandboxContext(newDomain,newDomainInstance);
    }

任何想法为什么它会在一台服务器上有所不同？我刚刚在损坏的服务器上安装了所有未完成的Windows更新,但它没有帮助.

如果我将PermissionSet更改为： –

PermissionSet permSet = new PermissionSet(PermissionState.Unrestricted);

所有代码都有效(但可能存在安全问题)
