Quote: A native Delphi XML parser and writer. Unique feature: Store, read and create any TPersistent object to/from XML directly (see Example5). This is done by iterating through all of the objects' published properties by use of RTTI (runtime type information). This feature is only available for D5 and up. I am programing an object serializer that unses RTTI in Delphi 7 and has the following functionality: it backups the state of every published property so they can be restored later through this serializer. It also transform the objecto to an XML string and Vice-Versa. The thing is this. I want to serialize an object A wich has a reference. Delphi Serialize Class To Xml. In computer science, in the context of data storage, serialization (or serialisation) is the process. JSON is a lighter plain-text alternative to XML which is also commonly used for client-server communication in. Implementing the interface marks the class as 'okay to serialize', and Java then handles.

Only closest option in Delphi is to stream the component using WriteComponent/WriteComponentRes of TStream/TWriter (used for Form storage as DFM, for example). It can be then read back using appropriate counterpart ReadComponent/ReadComponentRes.

Depend on your situation, simply calling .Assign method would work if you are coping data from one instance to another. But it only works between inherited classed which know about each other.

Can we find there something which will allow to pass objects states in more readable format?

There is a very powerful infrastructure available to do full serialization without knowing underlying class structure – RTTI (Run-time Type Information).

All functions we would be looking at are defined in TypInfo.pas unit.

Xml Serialize C# Class

First thing first. To be able to work within RTTI, you need to operate on the object which has publishedand public properties.

A function will return number and reference to the list (array) of properties published (public and published) by the class (VMT information). List will also include published methods. Simply walking through it will give you an access to property/method information.

In our example we are not interested in the published methods, so lets filter it out:

Now you are ready to get or set the value of the property:

C# Serialize Object

And now you are ready to serialize your object, store it, load definition and deserialize an object back. And it could be not necessarily the same object.
You would have to loop through the properties, read the values, and store it as an XML for later use.
