Is it possible to add an attribute to a property in a partial class?

Question

I don\'t think it\'s possible but since I haven\'t got a definite clarity from MSDN, I feel that it\'s best to ask. Suppose that we have a class as follows.

Answer 1

The best we could to to ensure decimals serialized to 2 decimal places was tp:

1. Use XlmAttributeOverides to ignore the decimal filed i.e not serialze it

var xmlAttributeOverrides = new XmlAttributeOverrides(); var ctrlSumAttributes = new XmlAttributes { XmlIgnore = true }; xmlAttributeOverrides.Add(typeof(Sepa.GroupHeader39), "CtrlSum", ctrlSumAttributes); var ser = new XmlSerializer( typeof( Sepa.Document ), xmlAttributeOverrides);

2. Use a partial class to add a string serialization of the ignored field

public partial class GroupHeader39 { [XmlElement("CtrlSum")] public string CtrlSumString { get => CtrlSum.ToString("F2"); set { /* required to work */ } } }

I hope this helps someone out with this issue.
