@Gravitas you are overly generous; the internals are not particularly elegant (nor do they need to be). Library code often accepts a big chunk-o'-ugly so that the calling application code can be clean. Use the BinaryFormatter to serialize an object to a byte. BinaryWriter is just for writing bytes to a. May 17, 2018 As a first example of serialization, let's do one of the easiest programs, but also one of the most useful: serializing data, and then deserializing data in simple class to and from a file. In this example, the data is not only serialized, but the structure of the data is saved too. Jun 22, 2009 Though serialization in itself is an extremely fast operation, the mapping of STreeNode object into TreeNode and vice versa is the operation that may hit performance if used to save huge and heavy structure. The mapping is done using recursive calling of efficient methods, yet this way is not recommended for heavy operations.

I am stuck on XML serialization of objects in VB.NET. I have created classes, some test XML documents and code. With the code I have now, I am able to deserialize an XML document to objects and then serialize that object back to a new XML document. However, I am stuck on creating my objects within VB.NET and then serializing. The debug just stops with a System.NullReferenceException. I can't figure it out. Please help.
Classes:Part.vb
partTest.xml Test Document used to deserialize:
Module_XML (Called from Main_Load)
TestPart() successfully deserializes the XML document above.Using that with:
successfully serializes xUnit to a new document.
In WriteXMLTest(), I am trying to buildup an object structure and then serialize it. This is where I fail:
I think my problem lies in either my classes or how I'm attempting to add to them. I've been stuck on this for a couple days and can't seem to figure it out.
