C＃Windows窗体应用程序逐行读取文本框

Question

I want to make a program that has a multiline textbox, and the program will read it line by line.
All I need is to get the line into a string, and after I'm finished with that line, it moves on.
How can I do that?
Is there a built in function, like there is the getline() function in c++ and c?
Should I use a normal textbox or a richtextbox?

TextBoxBase.Lines property is what you're looking for.

Per request, here's a sample:

Code:

namespace SomeApp
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            // For each line in the rich text box...
            for (int i = 0; i < richTextBox.Lines.Length; i++)
            {
                // Show a message box with its contents.
                MessageBox.Show(richTextBox.Lines[i]);
            }
        }
    }
}

Result:
