Question

The following code;

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));

Throws this exception in .NET 4.

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

Am I doing something wrong? Or is there a reasonable work around?

Many thanks!

There is a workaround as explained here – you can use XmlReaderSettings.CheckCharacters option to ignore validation of characters:

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