Question

private void textBox1_TextChanged(object sender, EventArgs e)
{
    if (a.Equals(b))
    {
        result = a.ToString();
        textBox1.Text = result;
        textBox1.TextAlign = HorizontalAlignment.Left;
    }
    else
        result = b.ToString();
    textBox1.Text = result;
    textBox1.TextAlign = HorizontalAlignment.Center;

What exactly are you are having problems with? What's currently not working with your if statements? — ryanyuyu, Jan 23 '15 at 15:01
Are you missing brackets for the else or is that intentional? — Thijs, Jan 23 '15 at 15:02
@Plue [that edit](http://stackoverflow.com/review/suggested-edits/6829258) is invalid. Don't change the code of a question, especially since the missing brackets may be the source of the issue. — CodeCaster, Jan 23 '15 at 15:03

Most probably you forgot to add brackets in your else statement.

Try this code:

private void textBox1_TextChanged(object sender, EventArgs e)
{
    if (a.Equals(b))
    {
        result = a.ToString();
        textBox1.Text = result;
        textBox1.TextAlign = HorizontalAlignment.Left;
    }
    else
    {
        result = b.ToString();
        textBox1.Text = result;
        textBox1.TextAlign = HorizontalAlignment.Center;
    }
}

It is always good practice to place curly brackets in if, else statements, loops, etc.
