Question

I have TextBox in a Windows form application. And I write a text in it.

eg.

texbox.Text = " first line ";
....
textbox.Text = "second line";

When I write second text, the first line is deleted. How to leave the first line and write next texts in next line in the TextBox?

I want the following result:

first line
second line

Answer 1

textbox.text = "first line";
textbox.text += "\nsecond line";

or

textbox.text = "first line";
textbox.text = textbox.text + "\nsecond line";
