Reset the position of the stream before reading.

You also have to set the position to 0 if you want to read data from the beginning.

a usual error is to forget to set Position[^] to 0 after having written to a memory stream

private void SetFontSize(int start, int end, float fontsize)
{
    // save current selection
    int currentselstart = richTextBox1.SelectionStart;
    int currentsellength = richTextBox1.SelectionLength;
    
    richTextBox1.SuspendLayout();
    
     richTextBox1.Select(start, end);
     richTextBox1.SelectionFont = new Font(richTextBox1.Font.FontFamily, fontsize);
    
    richTextBox1.ResumeLayout();

    // restore the previous selection    
    richTextBox1.Select(currentselstart, currentsellength);
    richTextBox1.Focus();
}
