Convert an object to an XML string

Question

I have got a class named WebserviceType I got from the tool xsd exe from an XSD file     Now I want to deserialize an instance of an WebServiceType object to a string   How can I do this   The MethodCheckType object has as params a WebServiceType array   My first try was like I serialized it  with a XmlSerializer and a StringWriter  while serializing I used a StringReader    This is the method in which I serialize the WebServiceType object   XmlSerializer serializer   new XmlSerializer typeof MethodCheckType            MethodCheckType output   null          StringReader reader   null              catch global exception  logg it and throw it         try                       reader   new StringReader path               output    MethodCheckType serializer Deserialize reader                     catch  Exception                        throw                    finally                       reader Dispose                       return output WebService      Edit      Maybe I could say it in different words  I have got an instance of this MethodCheckType object an on the other hand I have got the XML document from which I serialized this object  Now I want to convert this instance into a XML document in form of a string  After this I have to proof if both strings  of XML documents  are the same  This I have to do  because I make unit tests of the first method in which I read an XML document into a StringReader and serialize it into a MethodCheckType object

I realize this is a very old post  but after looking at L B s response I thought about how I could improve upon the accepted answer and make it generic for my own application  Here s what I came up with   public static string Serialize lt T gt  T dataToSerialize        try               var stringwriter   new System IO StringWriter            var serializer   new XmlSerializer typeof T            serializer Serialize stringwriter  dataToSerialize           return stringwriter ToString              catch               throw           public static T Deserialize lt T gt  string xmlText        try               var stringReader   new System IO StringReader xmlText           var serializer   new XmlSerializer typeof T            return  T serializer Deserialize stringReader             catch               throw            These methods can now be placed in a static helper class  which means no code duplication to every class that needs to be serialized

Here are conversion method for both ways  this   instance of your class  public string ToXML                 using var stringwriter   new System IO StringWriter                           var serializer   new XmlSerializer this GetType                 serializer Serialize stringwriter  this               return stringwriter ToString                      public static YourClass LoadFromXMLString string xmlText                using var stringReader   new System IO StringReader xmlText                         var serializer   new XmlSerializer typeof YourClass                 return serializer Deserialize stringReader  as YourClass

This is my solution  for any list object you can use this code for convert to xml layout  KeyFather is your principal tag and KeySon is where start your Forech   public string BuildXml lt T gt  ICollection lt T gt  anyObject  string keyFather  string keySon                var settings   new XmlWriterSettings                       Indent   true                    PropertyDescriptorCollection props   TypeDescriptor GetProperties typeof T            StringBuilder builder   new StringBuilder            using  XmlWriter writer   XmlWriter Create builder  settings                         writer WriteStartDocument                writer WriteStartElement keyFather               foreach  var objeto in anyObject                                writer WriteStartElement keySon                   foreach  PropertyDescriptor item in props                                        writer WriteStartElement item DisplayName                       writer WriteString props item DisplayName  GetValue objeto  ToString                         writer WriteEndElement                                      writer WriteEndElement                              writer WriteFullEndElement                writer WriteEndDocument                writer Flush                return builder ToString
