How to parse user input from a textarea line by line

If I have a variable that contains text information (say taken from a textarea), how can I read开发者_运维技巧 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())) {
     //...
}

Try to use

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

This is an old question but this could help! Personally I use this code to handle all Operating System:

myString.Split(new[] { "\r\n", "\r", "\n" }, StringSplitOptions.RemoveEmptyEntries)

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