Question

If I have a variable that contains text information (say taken from a textarea), how can I read the text content held in a string variable line by line?

The text entered in the text area will have \n (enter key) to separate the line.

You can use a StringReader:

var reader = new StringReader(textbox.Text);
string line;
while (null != (line = reader.ReadLine())) {
     //...
}
