Serialization/desrialization

[Ann_2020]

I have some doubts regarding serialization/deserialization.It would be really great if anyone could help me out!!!

Im preparing a questionnaire wizard.Which contains different groups with a set of questions in each group.I need to store data as xml using serialization and deserialization.

Xml strucutre goes like this.DotNet->CSharp->Document->Questionnaires|->Questionnaire.

i need to append each questionnaire as a new Questionnaire in the node Questionnaires.

Im able to serialize and store as xml.But next time when i save a new questionnaire ,the existing one is gettin overwritten..

Deserialization is also workin...But dont know how to append a new questionnaire to Questionnaires.

Plz help....

I guess this has got nothing to do with Serialization and Deserialization. All you are doing is saving a questionnaire as XML file and reading it back. You have couple of options here on how to access the XML file and read/write data from it.

1. Use a dataset to read the XML file, do the changes in the dataset and save it back as XML File

2. Use System.XML namespace.
