How to Serialize and Deserialize a class containing DateTimeOffset Property in C#

DateTimeOffset-Serialization.txt

DateTimeOffset fails silently with XmlSerializer; instead use DataContractSerializer.
Apparently XMLSerializer does not support certain aspects of the DateTimeOffset structure.. WTF?!

Generic example below (uses UTF8 encoding here, but you can use whatever you like):

     public static string SerializeObject<T>(T instance) where T : class  
     {  
       try  
       {  
         MemoryStream stream = new MemoryStream();  
         DataContractSerializer serializer = new DataContractSerializer(typeof(T));  
         serializer.WriteObject(stream, instance);  
         return new UTF8Encoding().GetString(stream.ToArray());  
       }  
       catch(Exception ex)  
       {  
         ...  
       }  
     }  
     
OR with no err handling, let the consumer handle error:
  using (MemoryStream stream = new MemoryStream())
  {
      DataContractSerializer dcSerz = new DataContractSerializer(typeof(T));
      dcSerz.WriteObject(stream, instance);
      string resultAsXml = new UTF8Encoding().GetString(stream.ToArray());
      return resultAsXml;
  }
     
     
     

And here's how to deserialize it again:

public static T DeserializeObject<T>(string data) where T : class  
     {  
       try  
       {  
         MemoryStream memoryStream = new MemoryStream(new UTF8Encoding().GetBytes(data));  
         DataContractSerializer serializer = new DataContractSerializer(typeof(T));  
         return (T)serializer.ReadObject(memoryStream);  
       }  
       catch  
       {  
         ...  
       }  
     }
