c# - 不可打印字符的序列化

Question

以下代码；

var c = (char) 1;

var serializer = new XmlSerializer(typeof (string));

var writer = new StringWriter();
serializer.Serialize(writer, c.ToString()); 
var serialized = writer.ToString();

var dc = serializer.Deserialize(new StringReader(serialized));

在 .NET 4 中抛出此异常。

Invalid Operation Exception - There is an error in XML document (2, 12). '', hexadecimal value 0x01, is an invalid character. Line 2, position 12

我做错了什么吗？还是有合理的解决方法？

非常感谢!

有一个解决方法 explained here - 你可以使用 XmlReaderSettings.CheckCharacters忽略字符验证的选项:

XmlReader xr = XmlReader.Create(new StringReader(serialized),
    new XmlReaderSettings { CheckCharacters = false });
var dc = (string)serializer.Deserialize(xr);
