Use the TextBox.Lines property which is a string[] array representing the lines of text:

textBox.Lines.Count > 0 ? textBox.Lines[0] : null

or alternatively (and shorter):

textBox.Lines.FirstOrDefault()

---

myTextBox.Text.Split(Environment.NewLine).FirstOrDefault();

---

yourtextbox.Lines[0]

---

if you split the text by \n character you will get the text as line by line as a string array. The first index of the array is the first row of your multine textbox. for example:

string firstLine = TextBox1.Text.Split('\n')[0];

This is for textbox in asp.net controls. If you want to obtain the same thing in a windows form application, you should write example code above:

string firstLine = textBox1.Lines[0];
