I'm running into problems serializing lots of objects in .NET. The object graph is pretty big with some of the new data sets being used, so I'm getting: System.Runtime.Serialization.SerializationException "The internal array cannot expand to greater than Int32.MaxValue elements." Has anyone else hit this limit? How have you solved it?...
I have a requirement to map all of the field values and child collections between ObjectV1 and ObjectV2 by field name. ObjectV2 is in a different namspace to ObjectV1. Inheritence between the template ClassV1 and ClassV2 has been discounted as these 2 classes need to evolve independently. I have considered using both reflection (which ...

Hi everyone, I have an N-tier structure composed of WCF nodes. I need to occasionally pass very large volumes of data from a terminal node to the top node and I would like to avoid deserializing the very large data field during the intermediate hops. I can't pass directly to the top due to our fall over strategy. Is there any way to avo...
Is there a way to serialize a lexical closure in Python using the standard library? pickle and marshal appear not to work with lexical closures. I don't really care about the details of binary vs. string serialization, etc., it just has to work. For example: def foo(bar, baz) : def closure(waldo) : return baz * waldo ...

I am looking for a way to convert an object tree to XML. It would be fun to write, but I am sure someone has already written it. Here is my wish list: It should not care about constructors It should ideally handle circular references (not too fussed how) It should not require changes to the objects - e.g., no custom attributes It shoul...
Hi, I have a file that contains serialized Java classes. I would like to parse this file in order to get a list of the classes in the file and the serialVersionUID of each class. Is there a tool anyone can recommend to do this, or perhaps someone could offer some pointers on where I should start to accomplish this myself? Cheers Rich...

Hi all, I'm working on a project that involves some home-made (de-)serialization code, and I have run into some issues with the deserializing of a List. The following code is throwing a NullReferenceException on the second line, even though the var list is not null, and happily reports Count = 0 when hovering my mouse over it. System.C...

Hi, I am currently looking into writing a fast deesrialisation/parsing of a custom message format which are similar to BNF syntax. There are maybe 50 different objects involved. The grammar of the objects contains a recursive definition which is the biggest problem for me at the moment. Do you know any good examples or would you write yo...
