From: AA2e72E on 19 Mar 2010 07:39 I had already tried your suggestion ........ XmlSerializer ser = new XmlSerializer(myFile.GetType()); MemoryStream ms = new MemoryStream(); ser.Serialize(ms, myFile); ........... but without success; I encounter <>f__AnonymousType0`2[System.String,System.Int32] cannot be serialized because it does not have a parameterless constructor.

Ah, yes... That does make sense. I think reflection as Alberto replied earlier would work. Mike

You would need to make a new object call it MyObject and serialize that. public class MyObject { public string FullName {get; set;} public int FileLength {get; set;} } var myobject = (from file in fileList // Most recent file orderby file.CreationTime descending select new MyObject{ FullName = file.FullName, FileLength = file.Length}).First(); You should be able to serialize MyObject. |
