how to persist text data in winforms app?

I am working on a winforms app using C# and wanted to add a save feature to a few parts where the user would be bale to enter text into a textbox and have it saved for next time.

how is this implemented in winforms? I am trying a local xml file and failing to persists the text while being able to read it. data.xml is the local file in my project root folder.

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(@"(full path)\visual studio 2015\Projects\My_helper\data.xml");

string subject = xmlDoc.DocumentElement.SelectSingleNode(@"./content/reminder_email/subject").InnerText.ToString();

string body = xmlDoc.DocumentElement.SelectSingleNode(@"./content/reminder_email/body").InnerText.ToString();

The XML approach is a good one, I've used it a lot. But beware where you choose to store it. For instance, if your application is installed to ProgramFiles, you won't be able to write there. You'd have to store it in ProgramData, or in the user's space.

As for the application settings, it's not really a bad way to go, but it's also not meant to be data storage. So if it's really data you're storing, use something meant for that purpose: a database or at least XML.

Using settings is probably the easiest approach.

Read: https://msdn.microsoft.com/en-us/library/aa730869(v=vs.80).aspx

  • Create a setting in the solution explorer as a string type
  • Assign using Properties.Settings.Default.Your Setting Name = TextBox1.Text
  • Read using TextBox1.Text = Properties.Settings.Default.Your Setting Name

Don't forget to call Properties.Settings.Default.Save(); after changing a setting.
