| // For example classes generated by adding a reference to a WCF service. | |
| // IEnumerable and arrays are tricky to serialize to xml, so here is the tip. | |
| // First, I build a dictionary and put xml serialiers instance like this: | |
| // _xmlSerializers.Add(typeof(SomeType), new XmlSerializer(typeof(SomeType), "a namespace")); | |
| // _xmlSerializers.Add(typeof(List<SomeType>), new XmlSerializer(typeof(List<SomeType>), "a namespace")); | |
| // Then te code to serialize a class: | |
| string serialized = null; | |
| bool serializerFound = false; | |
| using (var xwriter = new Utf8StringWriter()) | |
| { | |
| if (!_xmlSerializers.ContainsKey(@object.GetType())) | |
| { | |
| serializerFound = false; | |
| IEnumerable<dynamic> objectAsIenumerable = @object as IEnumerable<dynamic>; | |
| if (objectAsIenumerable != null) | |
| { | |
| // create a typed list from the enumeration | |
| Type listItemType = null; | |
| if (@object.GetType().GetGenericArguments().Length > 0) | |
| listItemType = @object.GetType().GetGenericArguments()[0]; // IEnumerable<T> | |
| else | |
| listItemType = @object.GetType().GetElementType(); // [T] | |
| Type genericListType = typeof(List<>); | |
| Type typedListType = genericListType.MakeGenericType(listItemType); | |
| dynamic typedList = Activator.CreateInstance(typedListType); | |
| IEnumerator<dynamic> enumerator = objectAsIenumerable.GetEnumerator(); | |
| while (enumerator.MoveNext()) | |
| typedList.Add(enumerator.Current); | |
| if (!_xmlSerializers.ContainsKey(typedListType)) | |
| throw new Exception($"No xml serializer defined for type {typedListType}"); | |
| _xmlSerializers[typedListType].Serialize(xwriter, typedList); | |
| serializerFound = true; | |
| serialized = xwriter.ToString(); | |
| } | |
| } | |
| else | |
| { | |
| _xmlSerializers[@object.GetType()].Serialize(xwriter, @object); | |
| serializerFound = true; | |
| serialized = xwriter.ToString(); | |
| } | |
| } | |
| if (!serializerFound) | |
| throw new Exception($"No xml serializer defined for type {@object.GetType()}"); |
