You have HTML entities in the code, which you would have to convert back to real characters.

This for example:

if (a &gt;= 50 &amp; a &lt; 60 &amp; Convert.ToInt64(textBox2.Text) &gt;= 50)

should be:

if (a >= 50 & a < 60 & Convert.ToInt64(textBox2.Text) >= 50)

private void button1_Click(object sender, EventArgs e)
{
    double a;
    a = ((Convert.ToInt16(textBox1.Text) * 0.4) + (Convert.ToInt16(textBox2.Text) * 0.6));
    if (a >= 50 && a < 60 && Convert.ToInt64(textBox2.Text) >= 50)
    {
        label4.Text = "Ge&ccedil;ti";
        label5.Text = "CC";
        textBox3.Text = a.ToString();
    }
    else
    {
        label4.Text = "KALDI";
        label5.Text = "FF";
        textBox3.Text = a.ToString();            
    }
}

private void button2_Click_1(object sender, EventArgs e)
{
    textBox1.Text = "";
    textBox2.Text = "";
    textBox3.Text = "";
    label4.Text = "Durum";
    label5.Text = "Sonuc";
}
