将类序列化为XML时出错

Question

I am serializing Linq object to using XmlSerializer but I am getting

"There was an error reflecting type 'System.Collections.Generic.List`1"

I have extended the Linq object with Serilizable attributes, something that m I doing incorrect here?

[Serializable]
public partial class Customer
{
}

[Serializable]
public partial class Comment
{
}


[Serializable]
public class CustomerArchive
{
    public Customer MyCustomer{ get; set; }
    public Comment MyComment { get; set; }
}



 internal static void Serialize(IEnumerable<CustomerArchive> archive, string fileName)
 {
      var serializer = new XmlSerializer(typeof(List<CustomerArchive>)); // Error

      using (var stream = File.Create(fileName))
      {
           using (var sw = new StreamWriter(stream))
           using (var writer = new XmlTextWriter(sw)
           {
                Indentation = 5,
                Formatting = Formatting.Indented
           })
           serializer.Serialize(writer, new List<CustomerArchive>(archive));
       }
 }

I think you have some properties inside MyCustomer class that cannot be serialized by the XML Serializer . Like a generic Dictionary<> for example.

Put [XmlIgnore] attribute on those properties and try again. If after that your code works you will simply need to make some surrogate properties that would serialize to XML and back without any issues.
