How to open text in Notepad from .NET?

Question

When I click a button on a Windows Forms form, I would like to open a Notepad window containing the text from a TextBox control on the form.

How can I do that?

Answer 1

Save the file to disk using File.WriteAllText:

File.WriteAllText("path to text file", myTextBox.Text);

Then use Process.Start to open it in notepad:

Process.Start("path to notepad.exe", "path to text file");
