Json.NET 和混淆、反序列化不起作用

Json.NET and Obfuscation, deserialization not working

我想分享我的团队的一个解决方案,我发现它可以克服在尝试结合 Json.Net 和混淆时出现的问题。

我的配置:VS2013、C#、.NET 4.0、Json.Net 7.0.1、CodeWall/Crypto 混淆器。

一切正常,直到我混淆我的代码。之后我无法反序列化我的 json 文件(已正确序列化!)。

我们的解决方案提供了 DefaultSerializationBinder class 的 "sort of hacking",您可以简单地从源代码中挑选并随意修改(或提供您自定义的抽象覆盖 class序列化绑定器)。当它试图从程序集名称中发现正确的程序集时,问题似乎出现了……这里的混淆不会匹配两者。

此处是您需要重写的方法代码:

private static Type GetTypeFromTypeNameKey(TypeNameKey typeNameKey)
{
    string assemblyName = typeNameKey.AssemblyName;
    string typeName = typeNameKey.TypeName;

    if (assemblyName != null)
    {
        // look, I don't like using obsolete methods as much as you do but this is the only way
        // Assembly.Load won't check the GAC for a partial name
        Assembly assembly = Assembly.LoadWithPartialName(assemblyName);

        if (assembly == null)
        {
            string partialName = assemblyName;
            var elements = assemblyName.Split(',');
            if (elements.Length > 0)
            {
                partialName = elements[0];
            }
            // will find assemblies loaded with Assembly.LoadFile outside of the main directory
            Assembly[] loadedAssemblies = AppDomain.CurrentDomain.GetAssemblies();
            foreach (Assembly a in loadedAssemblies)
            {
                if (a.GetName().Name == assemblyName || a.FullName == assemblyName || a.GetName().Name == partialName)
                {
                    assembly = a;
                    break;
                }
            }
        }

        if (assembly == null)
        {
            throw new JsonSerializationException(string.Format("Could not load assembly '{0}'.", assemblyName));
        }
        Type type = assembly.GetType(typeName);

        if (type == null)
        {
            throw new JsonSerializationException(string.Format("Could not find type '{0}' in assembly '{1}'.", typeName, assembly.FullName));
        }

        return type;
    }
    else if (typeName != null)
    {
        return Type.GetType(typeName);
    }
    else
    {
        return null;
    }
}

希望对您有所帮助!
