The quest for 0x0B

Question

I get this error when reading some data from an SQL column then converting it to XML:

\"System.InvalidOperationException: There is an error in XML document (182, 16

Answer 1

Finally found it !

The .NET XML serializer was escaping the invalid character when serializing it, but then it was un-escaping it before de-serialization.

So I had to search for the escaped  to find the un-escaped 0x0B ... seriously not funny guys!

So this:

  SELECT * from Mytable where Column like '%' + '' + '%'

Will actually find this:

      313_other_10

And while this looks like valid XML it will throw an invalid character exception when :

    XmlSerializer xs = new XmlSerializer(Type.GetType(Hashtable));
    StringReader stringReader = new StringReader(xml);
    obj = xs.Deserialize(stringReader);

Many thanks to people who jumped in to help! It was unvaluable help!
