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 :
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();
}
so when click button1 it the code will be like this:
textBox2=text1[1];
[1] mean the first line How can i do it automaticaly by one click ? or with one click the first line to textBox2 the second to textBox3 .....ect..
plz i want the code and where i should put it ^_^
or if there is another way to do that
The property Lines is there for you
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 we should always check the number of lines present in textBox1)
TextBox[] text = new TextBox[] {textBox2, textBox3, textBox4};
if(textBox.Lines.Length >= 3)
{
for(int x = 0; x < 3; x++)
text[x] = textBox1.Lines[x];
}
Simple programming read and write a one-by-one line from multiline textBox in C#
Write line one-by-one:
textbox1.AppendText("11111111+");
textbox1.AppendText("\r\n222222222");
textbox1.AppendText("\r\n333333333");
textbox1.AppendText("\r\n444444444");
textbox1.AppendText("\r\n555555555");
Read line one-by-one:
for (int i = 0; i < textbox1.Lines.Length; i++)
{
textbox2.Text += textbox1.Lines[i] + "\r\n";
}
You can use following snippet for reading comma separated and newline separated values from multiline textbox -
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.
