How to generate xml data from edifact data with c# code

I am new to edifact parsing.Could you please share sample code which converts edifact string to xml with c# code.I can't use third party libraries in my project.Please help with samples.

With EdiFabric, you can use the good old XmlSerializer to write all the data out to an XML, like this. BTW, I work for EdiFabric, so let me know if you have any questions related to the product.
