I have a simple program it has a function to read a line from multiline textBox when i press a button what i made to do that is this code :
我有一个简单的程序，当我按下一个按钮时，它具有从多行文本框中读取一行的功能，这是我所做的代码：
TextReader read = new System.IO.StringReader(textBox1.Text);
int rows = 100;
string[] text1 = new string[rows];
for (int r = 1; r < rows; r++)
{
text1[r] = read.ReadLine();
}

所以当点击 button1 时，它的代码将是这样的：
textBox2=text1[1];

The property Linesis there for you
物业Lines为您服务
if(textBox1.Lines.Length > 0)
textBox2.Text=textBox1.Lines[0];
or, put your textboxes ordered in a temporary array and loop on them (of course checks the number of lines present in textBox1)
或者，将您的文本框排序在一个临时数组中并在它们上循环（当然检查 textBox1 中存在的行数）
TextBox[] text = new TextBox[] {textBox2, textBox3, textBox4};
if(textBox.Lines.Length >= 3)
{
for(int x = 0; x < 3; x++)
text[x] = textBox1.Lines[x];
}

You can use following snippet for reading comma separated and newline separated values from multiline textbox -
您可以使用以下代码段从多行文本框中读取逗号分隔和换行符分隔的值 -
if (!string.IsNullOrEmpty(Convert.ToString(txtBoxId.Text)))
{
string IdOrder = Convert.ToString(txtBoxId.Text.Trim());
//replacing "enter" i.e. "\n" by ","
string temp = IdOrder.Replace("\r\n", ",");
string[] ArrIdOrders = Regex.Split(temp, ",");
for (int i = 0; i < ArrIdOrders.Length; i++)
{
//your code
}
}
I Hope this would help you.
我希望这会帮助你。

Simple programming read and write a one-by-one line from multiline textBox in C#
简单编程从C#中的多行textBox读写一行一行
Write line one-by-one:
一行一行写：
textbox1.AppendText("11111111+");
textbox1.AppendText("\r\n222222222");
textbox1.AppendText("\r\n333333333");
textbox1.AppendText("\r\n444444444");
textbox1.AppendText("\r\n555555555");
Read line one-by-one:
逐行阅读：
for (int i = 0; i < textbox1.Lines.Length; i++)
{
textbox2.Text += textbox1.Lines[i] + "\r\n";
}
