Hello,

In my program I need to fill a TextBox Object from the second line to the end of a richTextBox Control. I used the code below but I wonder why it does not work. Could you please let me know how could I make it work?

C#

private void button1_Click(object sender, EventArgs e)
{

     int intLng = richTextBox1.Lines.Length;
     TextBox MyTextBox = new TextBox();
     MyTextBox.Lines = new String[intLng - 1];
     MyTextBox.Multiline = true;

     for ( int i =1 ; i < intLng ; i ++ )
     {
         MyTextBox.Lines[i - 1] =richTextBox1.Lines[i].ToString(); 
     }
}

Thank you a lot

Always use PRE tags to format code part. It makes the question readable.

You will have to create a array of strings and populate it. Then you can set this as lines for the textbox.

C#

int intLng = richTextBox1.Lines.Length;
            TextBox MyTextBox = new TextBox();
            MyTextBox.Lines = new String[intLng - 1];
            MyTextBox.Multiline = true;
            string[] str = new string[intLng - 1];
            for (int i = 1; i < intLng; i++)
            {
                str[i - 1] = richTextBox1.Lines[i].ToString();
            }
            MyTextBox.Lines = str;

It's public, but you have to pass in the initialized array.

Sucks, sorry, but it's how it works.

LINQ to the rescue!

private void button1_Click(object sender, EventArgs e)
{
    TextBox MyTextBox = new TextBox();
    MyTextBox.Multiline = true;
    MyTextBox.Lines = richTextBox1.Lines.Skip(1).ToArray();

}

I didn't replied with LINQ expression since I don't know if OP is using .Net 3.5 or above.

are you suggesting people aren't? hrm...maybe that explains the re-released tools to get people off of VB6...
