How to Show New Line command in text box?

Hi i am doing a small project in C#, and i need to know what commands are comming from input source so i can do my work accordingly.. here is example...

textBox1.Text = "First line \nSecond line";
richTextBox1.Text = "First line \nSecond line";

Richtextbox shows this output:

First line

Second line

Textbox show this output:

First line Second line

please tell me how to show new line "\n" or return "\r" or similar input as a character output in text or richtextbox. so i can know that newline command is coming from input data.

for example text or richtext box will show this output.

First line \nSecond line

thankx in advance.

This is the Image how your text box will appear Change Your text box property from single line to Multiline then it will change to new line

TextBox1.TextMode = TextBoxMode.MultiLine;
        TextBox1.Text = "First line \n New line ";

For winforms application set

this.textBox1.Multiline = true;

and use "\r\n" as

textBox1.Text = "First line \r\nSecond line";

You want to either prefix your string with @ or you can use a double slash before each n (\n). Both of these are ways of escaping the \ so that it displays instead of being treated as part of a new line.

 @"This will show verbatim\n";
 "This will show verbatim\\n";

You can utilize this by performing a Replace on your incoming text

richTextBox1.Text = richTextBox1.Text.Replace("\n", "\n\\n");
richTextBox1.Text = richTextBox1.Text.Replace("\r\n", "\r\n\\n");

In the replace, I left the original linebreak so that it will be there, just followed by the displaying version. You can take those out if you dont want that. :)

Lets say that i have a string which have new line : 

 string st = "my name is DK" + Environment.NewLine + "Also that means it's my name";

Now that i want to show that there is new line in my text there you go :

 textBox1.Text = st.Replace(Environment.NewLine, "%");

This will show the newline chat with % sign

Use the combination "\r\n" (or Environment.NewLine constant which contains just that).
