C#WinForms:deploy后动态设置的图标不'；t更新

感谢您对如何解决此问题提出的建议。：-）

public partial class Form1 : Form
{
    private Bitmap bitmap;
    private IntPtr hicon;
    private Icon selectedIcon;

    public Form1()
    {
        InitializeComponent();

    }

    private void SetUpIcon(Bitmap resource)
    {
        hicon = resource.GetHicon();
        selectedIcon = Icon.FromHandle(hicon);
        this.Icon = selectedIcon;
    }

    private void btnFirstIcon_Click(object sender, EventArgs e)
    {
        bitmap = Resources.Resources.save_main;
        SetUpIcon(bitmap);
        lblStatus.Text = "First icon set up!";
    }

    private void btnSecondIcon_Click(object sender, EventArgs e)
    {
        bitmap = Resources.Resources.search;
        SetUpIcon(bitmap);
        lblStatus.Text = "Second icon set up!";
    }

    private void btnThirdIcon_Click(object sender, EventArgs e)
    {
        bitmap = Resources.Resources.team;
        SetUpIcon(bitmap);
        lblStatus.Text = "Third icon set up!";
    }
