Question

我有两个方法，如下所示，读取和写入我的XML文件。加密XML文件并允许从我的代码中读/写它的最简单方法是什么？

阅读XML文件

XmlSerializer SerializerObj = new XmlSerializer(typeof(List<ItemsUnderControlObject>));
// Create a new file stream for reading the XML file
FileStream ReadFileStream = new FileStream(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location.ToString()) + @"\itemlist.xml", FileMode.Open, FileAccess.Read, FileShare.Read);

// Load the object saved above by using the Deserialize function
MyGlobals.ListOfItemsToControl = (List<ItemsUnderControlObject>)SerializerObj.Deserialize(ReadFileStream);
// Cleanup
ReadFileStream.Close();

编写XML文件

// Create a new XmlSerializer instance with the type of the test class
 XmlSerializer SerializerObj = new XmlSerializer(typeof(List<ItemsUnderControlObject>));
// Create a new file stream to write the serialized object to a file
TextWriter WriteFileStream = new StreamWriter(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location.ToString()) + @"\itemlist.xml");
SerializerObj.Serialize(WriteFileStream, MyGlobals.ListOfItemsToControl);
WriteFileStream.Close();

查看System.Security.Cryptography命名空间，该命名空间提供了一堆允许加密/解密的类。许多人会接受一个流来解密，所以只需将你的WriteFileStream / ReadFileStream实例传递给一个加密类，就可以了。

下面的示例部分基于example in MSDN设置AES加密提供程序（并且可以适用于其他加密算法）。它需要一些初始化代码，这些代码取决于您的实现 - see example那里。

        using (AesCryptoServiceProvider aesAlg = new AesCryptoServiceProvider())
        {
            aesAlg.Key = Key;
            aesAlg.IV = IV;

            // Create a decrytor to perform the stream transform.
            ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV);

            // Create the streams used for encryption. 
            using (Stream msEncrypt = new FileStream(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location.ToString()) + @"\itemlist.xml"))
            {
                using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
                {
                    using (StreamWriter swEncrypt = new StreamWriter(csEncrypt))
                    {
                        // Create a new XmlSerializer instance with the type of the test class
                        XmlSerializer SerializerObj = new XmlSerializer(typeof(List<ItemsUnderControlObject>));
                        // Create a new file stream to write the serialized object to a file
                        SerializerObj.Serialize(swEncrypt, MyGlobals.ListOfItemsToControl);
                    }
                }
            }
        }

代码是尽力而为 - 目前没有办法构建它。所以可能需要一些TLC ......但是应该对所需要的内容有一个很好的了解。
