writing (inserting) text affter some character

Dozd

Hi, I want to write (insert) some text in existing text file, after some character from the text file. For example, to write text from text box after 50-th character in my text file. I use file stream, stream reader and stream writer.
thanks

Thanks for answer.
I think the problem with solution that you suggest is limitation of int type. If we have sting which contain more characters then integer could accept - so we need double - then we can not use substring method (it has integer for argument).
I made solution using lines instant of characters, but the idea was to use characters.
If somebody has idea is good to be post.

   private void button1_Click(object sender, EventArgs e)
        {
            int Length = textBox1.Text.Length;
            string TextData = textBox1.Text;

            string SubData = TextData.ToString().Substring(50);
            StreamWriter sw = new StreamWriter("Test.txt");
            sw.Write(SubData);
            sw.Close();

        }
