How to parse user input from a textarea line by line

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.

Answer 1

Try to use

string[] strings = yourString.Split(new string[] {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries)

Answer 2

You can use a StringReader:

var reader = new StringReader(textbox.Text);

string line;
while(null != (line = reader.ReadLine()) {
    //...
}

Answer 3

string[] splitInput = System.Text.RegularExpressions.Regex.Split(
                        InputString, "\r\n");
