vb.net select specific lines, from one line to another line

Question

I want write this code but it doesn't work for me

    Dim x

    Dim y

    x = TextBox1.Lines(1 - 5)


    y = TextBox1.Lines(6 - 10)


    TextBox2.Text = x
    TextBox3.Text = y

I want to take value from textbox.. x from line 1 to line 5 , y from line 6 to line 10

Answer 1

Make sure there are 10 lines in there, otherwise add some validation / error handling

Dim x = TextBox1.Lines.Take(5)
Dim y = TextBox1.Lines.Skip(5).Take(5)
TextBox2.Text = String.Join(Environment.NewLine, x)
TextBox3.Text = String.Join(Environment.NewLine, y)

You don't even need x and y according to your edit. Simply this

TextBox2.Text = String.Join(Environment.NewLine, TextBox1.Lines.Take(5))
TextBox3.Text = String.Join(Environment.NewLine, TextBox1.Lines.Skip(5).Take(5))
