城堡温莎InternalsVisibleTo Silverlight

Question

我正在使用Castle Windsor for SL v2.5.1.0.我有代理内部类(当然接口是公共的,但实现是内部的,所以消费者只知道接口).

我在使用内部类的程序集中使用以下属性

[assembly: InternalsVisibleTo("Castle.Core, PublicKey=002400000480000094000000060200000024000052534131000400000100010077F5E87030DADCCCE6902C6ADAB7A987BD69CB5819991531F560785EACFC89B6FCDDF6BB2A00743A7194E454C0273447FC6EEC36474BA8E5A3823147D214298E4F9A631B1AFEE1A51FFEAE4672D498F14B000E3D321453CDD8AC064DE7E1CF4D222B7E81F54D4FD46725370D702A05B48738CC29D09228F1AA722AE1A9CA02FB")]
[assembly: InternalsVisibleTo("Castle.Windsor, PublicKey=002400000480000094000000060200000024000052534131000400000100010077F5E87030DADCCCE6902C6ADAB7A987BD69CB5819991531F560785EACFC89B6FCDDF6BB2A00743A7194E454C0273447FC6EEC36474BA8E5A3823147D214298E4F9A631B1AFEE1A51FFEAE4672D498F14B000E3D321453CDD8AC064DE7E1CF4D222B7E81F54D4FD46725370D702A05B48738CC29D09228F1AA722AE1A9CA02FB")]
[assembly: InternalsVisibleTo("DynamicProxyGenAssembly2")]

在完整的.NET 4.0模式下,使用.NET 4.0 Castle程序集,这很好,我的类型代理正常.在Silverlight中,使用Silverlight Castle程序集,我得到:

Type ConsoleApplication4.MyTypeToBeProxied is not public. Can not create proxy for types that are not accessible.

此外,只是在解决问题,添加以下似乎没有区别......:

[assembly: InternalsVisibleTo("System.Core, PublicKey=00000000000000000400000000000000")]
[assembly: InternalsVisibleTo("System.Core, PublicKey=" +
"00240000048000009400000006020000002400005253413100040000010001008d56c76f9e8649" +
"383049f383c44be0ec204181822a6c31cf5eb7ef486944d032188ea1d3920763712ccb12d75fb7" +
"7e9811149e6148e5d32fbaab37611c1878ddc19e20ef135d0cb2cff2bfec3d115810c3d9069638" +

"123b37ab")]

我还在运行时验证了SL中动态托管程序集的名称实际上仍然是DynamicProxyGenAssembly2.

有任何想法吗？谢谢.

编辑:

我发现了我认为的问题:

Castle 4.0 for .NET具有:

private bool IsAccessible(Type target)
{
  //      ....
  return ((target.IsPublic || target.IsNestedPublic) || internalAndVisibleToDynProxy);

}

在DefaultProxyBuilder中...和SL 4有

private bool IsAccessible(Type target)
{
    target.IsNested();
    return (target.IsPublic || target.IsNestedPublic);
}

这是可以在Castle源中修复的东西吗？或者我是否需要/应该对DefaultProxyFactory进行子类化？

Answer 1

我在这方面有一些运气。老实说，我不确定为什么，但我无法重现 Krzysztof 描述的问题。我怀疑...也许...这与我的程序集是 SN'd 的事实有关...这需要我进行额外的更改...但是一旦我这样做了，我就能够解决代理问题用于 SL 测试应用程序中的内部类（具有公共接口）。

我必须对 Castle.Core 源代码进行的唯一更改是将字段设置ModuleScope.moduleBuilder为ModuleScope.moduleBuilderWithStrongName 受保护而不是私有。但同样，这只是必要的，以便我可以在 SL 中定义 SN 动态程序集，而 Castle.Core 中的 ModuleScope 对 SL 禁用了该程序集。所以，现在我有一个自定义 ModuleScope，如下所示：

    private class StrongNameModuleScope : ModuleScope
    {
        public StrongNameModuleScope()
        {
            var assemblyName = new AssemblyName("DynamicProxyGenAssembly2");
            // copied from another one of my SN assemblies (plus GetName() on assembly is security critical so I can't pull it off the executing assembly)
            byte[] publicKey = Convert.FromBase64String(@"ACQAAASAAACUAAAABgIAAAAkAABSU0ExAAQAAAEAAQBvwWquPXQG9zfemS8uDsFdGDScOCSjZ9aFsQDtrrAqKzvlxEGMz3t9Q9M3X9NKqy1ouLZi+sX8yVDafX+UnygFWWfOBosw9nGwG61MTKEhEjdKH0rECahGIXY+ETdNY64HduuH/BIbEs/RDhrrH2hiqGrOGb6AghD1sZ6g0A1qkg==");
            assemblyName.SetPublicKey(publicKey);
            AssemblyBuilder assembly = AppDomain.CurrentDomain.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.Run);
            ModuleBuilder module = assembly.DefineDynamicModule("DynamicProxyGenAssembly2");
            moduleBuilder = module;
            moduleBuilderWithStrongName = module;
        }
    }

和一个自定义的 DefaultProxyBuilder：

    /// <summary>
    ///   A custom IProxyBuilder copies from the full .NET Castle implementation that allows for proxies of internal types where the InternalsVisibleToAttribute is applied.
    /// </summary>
    private class DefaultProxyBuilder : IProxyBuilder
    {
       ...
        // Methods
        public DefaultProxyBuilder()
            : this(new StrongNameModuleScope())
        {
        }
       ...
        private static bool IsAccessible(Type target)
        {
            bool isTargetNested = target.IsNested;
            bool isNestedAndInternal = isTargetNested && (target.IsNestedAssembly || target.IsNestedFamORAssem);
            bool internalAndVisibleToDynProxy = ((!target.IsVisible && !isTargetNested) || isNestedAndInternal) && InternalsHelper.IsInternalToDynamicProxy(target.Assembly);
            return ((target.IsPublic || target.IsNestedPublic) || internalAndVisibleToDynProxy);
        }
    }

和一个自定义的 DefaultProxyFactory：

  /// <summary>
    ///   A simple DefaultProxyFactory to wrap the modified DefaultProxyBuilder.
    /// </summary>
    private class DefaultProxyFactory : global::Castle.Windsor.Proxy.DefaultProxyFactory
    {
        public DefaultProxyFactory()
        {
            generator = new ProxyGenerator(new DefaultProxyBuilder());
        }
    }

以及容器设置：

        container = new WindsorContainer();

        container.Kernel.ProxyFactory = new DefaultProxyFactory();

我不太喜欢修改 Castle.Core 源代码，所以我真的很想听听您的想法 Krzysztof...如果这个解决方案不适用于其他测试用例，也许您可​​以保护这些字段？
