请我需要帮助我正在为刽子手游戏编写代码，我只想更改表单的图标，我尝试使用 icon 属性但它不再起作用，请问我该怎么做，并且我也做了以下项目-->属性--->图标和清单，但它也不起作用这是我的游戏代码，它完美地工作：
private void button1_Click(object sender, EventArgs e)
{
stage_count++;//strat from stage 1
if (!int.TryParse(textBox1.Text.ToString(), out value))
return;//if user inter non_integer value do no thing and wait for new entry
if (key ==value )//directly if user guesses the key he/she wins the game
{
//view the seventh picture in hangman game
button1.Enabled = false;
textBox1.Text = "";
textBox1.Enabled = false;
pictureBox7.Visible = true;
pictureBox1.Visible = false;
pictureBox2.Visible = false;
pictureBox3.Visible = false;
pictureBox4.Visible = false;
pictureBox5.Visible = false;
pictureBox6.Visible = false;
groupBox1.Visible = true;
label1.Text = "Great... You Got It ^_^ ";
}
if (key > value)//guide the user to the correct answer
label1.Text = "Should Be Greater than" + value.ToString();
if (key < value)//guide the user to the correct answer
label1.Text = "Should Be Less than" + value.ToString();
if (key != value)
{
switch (stage_count)
{//this switch statement used to do some thing in each stage
case 1:
//view the first picture in hangman game
pictureBox1.Visible = true;
pictureBox2.Visible = false;
pictureBox3.Visible = false;
pictureBox4.Visible = false;
pictureBox5.Visible = false;
pictureBox6.Visible = false;
pictureBox7.Visible = false;
break;
case 2:
//view the second picture in hangman game
pictureBox1.Visible = false;
pictureBox2.Visible = true;
pictureBox3.Visible = false;
pictureBox4.Visible = false;
pictureBox5.Visible = false;
pictureBox6.Visible = false;

//view the third picture in hangman game
pictureBox1.Visible = false;
pictureBox2.Visible = false;
pictureBox3.Visible = true;
pictureBox4.Visible = false;

//it's the last try so diable the button and show the result
button1.Enabled = false;
textBox1.Text = "";
textBox1.Enabled = false;
groupBox1.Visible = true;
label1.Text = "YOU LOSE ,, IT WAS : " + key.ToString();
pictureBox1.Visible = false;
pictureBox2.Visible = false;
pictureBox3.Visible = false;
pictureBox4.Visible = false;
pictureBox5.Visible = false;
pictureBox6.Visible = true;
pictureBox7.Visible = false;
break;
}//end switch
//to make empty focused textbox
textBox1.Text = "";
textBox1.Focus();
}//end if
}
private void groupBox1_Enter(object sender, EventArgs e)
{
}
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{// if user want to playe new game the programm must enables the important controls and
//make the visible property equals to false for all the pictures boxes
if (radioButton1.Checked == true)
{
stage_count = 0;
key = (1 + obj.Next(99));
