title: How to save form data to XML or CSV?
body: <p>We have currently built a application that uses both textbox and combo boxes.</p>
  
  <p>We want to create a save button in a User Control Library that we have already built, and have it save all the data currently entered into an XML or CSV. The easier of the two would be preferred however I feel they're most likely the same difficulty.</p>
  
  <p>I am using WPF! I would like to make it so that the data is stored to a file. Nothing amazing needs to happen to the file, it's just a case of saving the data from the different textboxes, and comboBoxes and then just having them stored within a document.</p>
