c# - Class serialization in XML -

[xmlroot("class1")] class class1 { [(xmlelement("product")] public string product{get;set;} [(xmlelement("price")] public string price{get;set;} } 

this class. in price contains '£' symbol. after serializing xml '?' instead of '£'.

what need '£' in xml? or how can pass data in price cdata?

your problem must how xml written file.

i've written program uses information you've given me far, , when print xml string out, correct.

i conclude error happening either when data written xml file, or when read in xml file.
