如何隐藏XML文件内容 [英] How to hide XML files content

问题描述

我有一系列的，我想从客户端隐藏的XML文件，我想成为只可用于应用程序。我读写从/给他们使用的XmlSerializer 。如何才能做到这一点？我读到嵌入的资源，但是从我所看到的，我需要读取和写入使用某种流的文件。我想知道是否有另一种方法，它可以让我用从客户端访问它们的XmlSerializer 和隐藏它们。

I have a series of XML files which I want to hide from the client and I want to be available only for the application. I read and write from/to them using XmlSerializer. How can this be done? I read about embedded resources, but from what I've seen, I need to read and write to the files using some sort of stream. I was wondering if there is another approach which would allow me to access them using XmlSerializer and hide them from the client.

推荐答案

如果你只想隐藏它们（一种混淆以prevent的休闲的变化）你可以考虑COM preSS他们。例如在本C＃的反序列化功能的例子：

If you just want to hide them (kind of obfuscation to prevent casual changes) you may consider to compress them. For example this an example of C# deserialization function:

static T Deserialize<T>(string path, object obj)
{
    var serializer = new XmlSerializer(typeof(T));

    using (var stream = new GZipStream(File.OpenRead(path),
                                       CompressionMode.Decompress))
    {
        return (T)serializer.Deserialize(stream);
    }
}

您的客户将看到的二的文件，他们将不能够更改/检查它（而且它只是一个COM pressed流，使他们甚至不能解压缩它们）。为了清楚起见，这相当于序列功能：

Your customers will see a binary file and they won't be able to change/inspect it (moreover it's just a compressed stream so they can't even unzip them). For clarity this is equivalent serialization function:

static void Serialize<T>(string path, T obj)
{
    var serializer = new XmlSerializer(typeof(T));

    using (var stream = new GZipStream(File.Create(path),
                                       CompressionMode.Compress))
    {
        serializer.Serialize(stream, obj);
    }
}

注意：在你原来的问题，你没有说你的环境（？.NET Java的）什么，我提供了code假设你的编程在C＃中，但你可以申请同样的技术与你使用任何其他语言/环境。

Note: in your original question you didn't say anything about your environment (.NET? Java?), I provided code assuming you're programming in C# but you can apply same technique with any other language/environment you're using.

更新这是一个小的测试程序，看看它是如何工作的：

Update this is a small test program to see how it works:

public class Test
{
    public string Name { get; set; }
    public string Value { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        Serialize(@"c:\test.dat", new Test { Name = "A", Value = "B" });
    }

    // Place here Serialization<T>() method
}
