Question

我使用的是表单皮肤，而不是删除包括表单皮肤在内的所有内容，我一直在尝试使表单在启动时更改图标本身。我有徽标的位图版本，当我尝试引用这些位图时，出现错误：无法将类型'System.Drawing.Bitmap'隐式转换为'System.Drawing.Icon'

我尝试将图标添加到资源中并尝试引用它，但是只能引用我的位图。

public Main2()
    {
        InitializeComponent();

        Main2 f1 = new Main2();

        f1.Text = "Chaos V2.0.1c";

        f1.Icon = Properties.Resources.Logo; //problematic code (line 44)


        //My Tab Controls
        HomeTabControl.Visible = true;
        FullLuaTabControl.Visible = false;
        CommandTabControl.Visible = false;
        VIPServerTabControl.Visible = false;
        JailbreakTabControl.Visible = false;
        PhantomForcesTabControl.Visible = false;
        MM2TabControl.Visible = false;
        RoCitizensTabControl.Visible = false;
        BoogaBoogaTabControl.Visible = false;
        PrisonLifeTabControl.Visible = false;
        BuildABoatTabControl.Visible = false;
        LumberTycoon2TabControl.Visible = false;
        MeepCityTabControl.Visible = false;
        VehicleSimulatorTabControl.Visible = false;
        SuperPowerTrainingTabControl.Visible = false;
        BeeSwarmSimulatorTabControl.Visible = false;
        WeightLiftingTabControl.Visible = false;
        MiningSimulatorTabControl.Visible = false;
        BlobSimulatorTabControl.Visible = false;
        IceCreamSimulatorTabControl.Visible = false;
        PetSimulatorTabControl.Visible = false;
        StrucidTabControl.Visible = false;
        CounterBloxTabControl.Visible = false;
        ApocalypseTabControl.Visible = false;
        FullLuaScriptsTabControl.Visible = false;
        SettingsTabControl.Visible = false;
    }

我收到错误消息：“资源”不包含“徽标”的定义（第44行）

检查资源中的图标是否真的称为徽标。您可以将“位图”更改为“图标”，但是我不知道您是否会对结果满意。

public Icon ToIcon(Bitmap bmp)
{
    IntPtr hicon = bmp.GetHicon();
    Icon icon = Icon.FromHandle(hicon);
    DestroyIcon(hicon); // prevent memory leak.
    return icon;
}

[DllImport("user32.dll", CharSet = CharSet.Auto)]
extern static bool DestroyIcon(IntPtr handle);

单击按钮如何更改表单图标？
