C# programming writing to a file user data

I am trying to develop a user interface, where users can input their name, id and hometown and I am saving it into a text file.

File.WriteAllText(path,"name"+" " + textBox2.Text+ Environment.NewLine + 
"number"+" "+ textBox3.Text+Environment.NewLine + "town"+" " + 
textBox4.Text+Environment.NewLine );

This works but the data of the users is written in the text boxes and it works only for the first user, when I enter new data and click the button with the function, it overwrites the first user's data and that way I am not able to save more than 1 user's data.

Please suggest the required modification in the code.

Solution

  • File.WriteAllText will always overwrite the current file if it exists. Use File.AppendAllText instead.
