C#编程问题，程序无错误但没结果 private void Form1_Load(object sender, EventArgs e)

Fraction a = new Fraction(1, 3);

Fraction b = new Fraction(3, -12);
textBox1.Text += ("a= ");
a.Show(textBox1);
textBox1.Text += ("\r\nb= ");
b.Show(textBox1);
Fraction c = new Fraction();
c = a + b;textBox1.Text += ("\r\na+b= ");c.Show(textBox1);c = a * b;textBox1.Text += ("\r\na*b= ");c.Show(textBox1);
}
}

没错的话，你重新输入一次，看可以不？我以前也遇到过这种事情，重新一次就可以了。

输了好几次都不行
