c# - How can I use DataSets to store my application data in an XML file? -

I have datagroup view in my main window that I want to display my data. My app lets users input, change, and delete data. I told my friend the best method to do this so that they asked to store information in the XML file. So now I'm wondering how to use XmlSerializer. Can I create an XML document or dataset and value it, but still be able to read, add, and change those values ​​(via DataGrid view)? Apart from this, I would like to check whether the XML file has been created (if this is the first time, make XML; if not, then use the created XML file).

Also make sure it's in C #!

View XML as a data source for the DataGrid view
