MultiLine Textbox Question

I have a simple question. I'm just starting to program in the GUI for C#. My teacher wants us to output data in a multiline textbox, but I can't figure out how to do that.

For example, the program we are doing is calculating grades. The button we are clicking is supposed to output all information in to a textbox in a list format. So:
Name: Jason
Id: 1234
Average: 95
Letter Grade: A

My teacher is telling us that this needs to be in a single string like

Code:

---

stringVariable = name + "/r/n" +

---

but I know/hope that there is a better way to do this. Any help would be appreciated. Thanks,

stringVariable = name + System.Environment.Newline;

And that should have been \r\n. Backslashes, I believe.

Thank you

There are numerous ways to put multiline data into a TextBox, e.g.

C# Code:

myTextBox.Text = string.Format("Name: {0}\r\nId: {1}\r\nAverage: {2}\r\nLetter Grade: {3}",
                               name,
                               id,
                               average,
                               letterGrade);

or:

Code:

---

myTextBox.Lines = new string[] {"Name: " + name,
                                "Id: " + id.ToString(),
                                "Average: " + average.ToString(),
                                "Letter Grade: " + letterGrade};
