如何将序列化字节数组转换回其文本形式

Question

我有一个文本，它是一个对象的属性。对象获取XmlSerialized，然后在XML调用Text中有一个元素代表对象的文本。我想知道如何将它转回字符串。

序列化类型：XmlSerializer serizlizer = new XmlSerializer(typeof(Act));

课程中的财产：

[System.Runtime.Serialization.OptionalFieldAttribute()]
private byte[] ActTextField;

在xml文件中，它看起来像这样：

我甚至无法想象它的编码是什么以及如何对其进行解码。我尝试将其读入字节数组，但在应用了少量解码后它实际上无法正常工作 Encode.UTF8，Encode.ASCII，

Answer 1

对我来说看起来像Base64 - 只需使用

byte[] data = Convert.FromBase64String(base64Text);

如果这真的是一个 text 属性，那么根本就是使用base64，这很奇怪。我只期待文本。

要将二进制数据转换回文本，您需要知道使用哪种编码将其转换为二进制数据开始 - 而UTF-8最有可能 - 但所有重复的AAAAA...部分老实说，在那里使这个看起来很像文本。

编辑：现在我们已经看到了字段声明，我们可以看到它是一个byte[]开头，因此以这种方式对它进行编码是有意义的。从评论来看，听起来它实际上是一个Word文件 - 此时提取文本是一个非常独立的问题。
