我正在嘗試為我的應用程式實作主題轉換器。到目前為止，我已經這樣做了：
BaseForm - 具有要繼承的所有功能，它很長，所以如果需要，我會在這里發布。我遇到的問題如下：
MainForm 有一個按鈕可以打開 UserSettings，用戶可以在其中更改主題。問題是，我設法確定主題適用，但僅適用于 UserSettings 視窗，并且我希望它適用于任何打開的內容（如果還有其他內容）。
編輯：添加更多代碼
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Drawing.Text;
using System.Runtime.InteropServices;
using System.Runtime.Versioning;
using System.Windows.Forms;
using IniParser;
using ME___Tooling_Designer_App.Properties;
namespace ME___Tooling_Designer_App.Configuration;
public partial class UserSettings : BaseForm
{
public UserSettings()
{
InitializeComponent();
ApplyTheme();
ReadConfiguration();
}
// this is where the theme should be applied upon close
private void CBoxTheme_DropDownClosed(object sender, EventArgs e)
{
var parser = new FileIniDataParser();
var data = parser.ReadFile(_filePathSettings);
if (cBoxTheme.SelectedIndex == 0)
{
data["User_Settings"]["Theme"] = "Dark";
parser.WriteFile(_filePathSettings, data);
GlobalTheme = Enumerators.Theme.Dark;
}
if (cBoxTheme.SelectedIndex == 1)
{
data["User_Settings"]["Theme"] = "Light";
parser.WriteFile(_filePathSettings, data);
GlobalTheme = Enumerators.Theme.Light;
}
ApplyTheme();
}
public override void ApplyThemeSpecific(ThemeSettings settings)
{
panel1.BackColor = settings.PrimaryColor;
label2.ForeColor = settings.PrimaryFontColor;
btnExit.BackColor = settings.PrimaryColor;
btnExit.ForeColor = settings.PrimaryFontColor;
groupBox1.ForeColor = settings.PrimaryFontColor;
groupBox2.ForeColor = settings.PrimaryFontColor;
panel2.BackColor = settings.SecondaryColor;
}
編輯：這是 BaseForm 代碼：
using System.Collections.Generic;
using System.Drawing;
using System.Drawing.Text;
using System.Windows.Forms;
namespace ME___Tooling_Designer_App.Configuration;
public class BaseForm : Form
{
public static List<PrivateFontCollection> FontCollections;
public static Enumerators.Theme GlobalTheme { get; set; }
public void ApplyTheme()
{
var settings = new ThemeSettings();
if (GlobalTheme == Enumerators.Theme.Dark)
{
settings.PrimaryColor = Color.FromArgb(32, 30, 50);
settings.SecondaryColor = Color.FromArgb(32, 30, 45);
settings.TertiaryColor = Color.FromArgb(11, 7, 17);
settings.QuaternaryColor = Color.FromArgb(23, 21, 32);
settings.QuinaryColor = Color.FromArgb(35, 32, 39);
settings.SenaryColor = Color.LightGray;
settings.SeptenaryColor = Color.Gainsboro;
settings.PrimaryFontColor = Color.Gainsboro;
}
else if (GlobalTheme == Enumerators.Theme.Light)
{
settings.PrimaryColor = Color.LightGray;
settings.SecondaryColor = Color.GhostWhite;
settings.TertiaryColor = Color.Gainsboro;
settings.QuaternaryColor = Color.DarkGray;
settings.QuinaryColor = Color.Silver;
settings.SenaryColor = Color.Gray;
settings.SeptenaryColor = Color.Black;
settings.PrimaryFontColor = Color.Black;
}
ApplyThemeSpecific(settings);
}
public virtual void ApplyThemeSpecific(ThemeSettings settings)
{
}
}
public class Enumerators
{
public enum Theme
{
NotSet,
Light,
Dark
}
}
public class ThemeSettings
{
public Color PrimaryColor { get; set; }
public Color SecondaryColor { get; set; }
public Color TertiaryColor { get; set; }
public Color QuaternaryColor { get; set; }
public Color QuinaryColor { get; set; }
public Color SenaryColor { get; set; }
public Color SeptenaryColor { get; set; }
public Color PrimaryFontColor { get; set; }
}
這是我的 Program.cs：
using System;
using System.Windows.Forms;
using IniParser;
using ME___Tooling_Designer_App.Configuration;
using ME___Tooling_Designer_App.Forms;
namespace ME___Tooling_Designer_App
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
var parser = new FileIniDataParser();
var data = parser.ReadFile(Application.StartupPath @"\" "Config" @"\" "settings.ini");
var themeSetting = data["User_Settings"]["Theme"];
Application.EnableVisualStyles();
Application.SetHighDpiMode(HighDpiMode.SystemAware);
Application.SetCompatibleTextRenderingDefault(false);
if (themeSetting == "Light")
{
BaseForm.GlobalTheme = Enumerators.Theme.Light;
}
else if (themeSetting == "Dark")
{
BaseForm.GlobalTheme = Enumerators.Theme.Dark;
}
else
{
BaseForm.GlobalTheme = Enumerators.Theme.NotSet;
}
Application.Run(new Login());
}
}
}
嘗試將其作為 MainForm.ApplyTheme 執行，但仍然回傳 UserSettings
編輯：添加 MainForm 的片段：
namespace ME___Tooling_Designer_App.Forms;
public partial class MainForm : BaseForm
{
/// <summary>
/// Constructor
/// </summary>
public MainForm()
{
InitializeComponent();
ApplyTheme();
CreateDirectories();
CustomizeDesign();
InitializeDatFiles();
InitializeIniConfiguration();
ReadFont();
ReadComputer();
ReadSystem();
TestTrial();
DaysRemainColoring();
CompareComputerNameAndLicense();
lblUser.Text = Environment.UserName;
}
public override void ApplyThemeSpecific(ThemeSettings settings)
{
panelTopBar.BackColor = settings.PrimaryColor;
btnInfo.BackColor = settings.PrimaryColor;
btnMinimize.BackColor = settings.PrimaryColor;
btnExitTop.BackColor = settings.PrimaryColor;
panelCenter.BackColor = settings.SecondaryColor;
panelSideMenu.BackColor = settings.TertiaryColor;
panelSideMenuLogo.BackColor = settings.TertiaryColor;
btnMainMenu.BackColor = settings.TertiaryColor;
btnSettings.BackColor = settings.TertiaryColor;
btnSave.BackColor = settings.TertiaryColor;
btnLoad.BackColor = settings.TertiaryColor;
btnExit.BackColor = settings.TertiaryColor;
panelQuickView.BackColor = settings.QuaternaryColor;
panelMainMenu.BackColor = settings.QuinaryColor;
panelSettings.BackColor = settings.QuinaryColor;
btnNewProject.BackColor = settings.QuinaryColor;
btnExistingProject.BackColor = settings.QuinaryColor;
btnReadProject.BackColor = settings.QuinaryColor;
btnSearchProject.BackColor = settings.QuinaryColor;
btnUserSettings.BackColor = settings.QuinaryColor;
btnAppSettings.BackColor = settings.QuinaryColor;
}

解決辦法是加一個定時器
因為您的問題是更新所有視窗，所以您只需要為每個視窗添加一個計時器控制元件。
定時器：
基本形式：
using System.Drawing;
using System.Windows.Forms;
namespace WindowsFormsApp4 {
public partial class BaseForm : Form {
public BaseForm () {
}
private static Image baseImage=null;
public static Image BaseImage {
get {
return baseImage;
}
set {
baseImage = value;
}
}
}
}
設定表格：
using System;
namespace WindowsFormsApp4 {
public partial class SettingsForm : BaseForm {
public SettingsForm () {
InitializeComponent();
}
private void button1_Click (object sender, EventArgs e) {
BaseImage = Resource.tiger;
}
private void button2_Click (object sender, EventArgs e) {
BaseImage = Resource.windows;
}
private void timer1_Tick (object sender, EventArgs e) {
this.BackgroundImage = BaseImage;
}
}
}
表格1：
using System;
namespace WindowsFormsApp4 {
public partial class Form1 : BaseForm {
public Form1 () {
InitializeComponent();
}
private void button1_Click (object sender, EventArgs e) {
SettingsForm settingsForm=new SettingsForm();
settingsForm.ShowDialog();
}
private void timer1_Tick_1 (object sender, EventArgs e) {
this.BackgroundImage = BaseImage;
}
}
}
資源.resx：
輸出：
您可以根據需要更改它。
如果您有任何問題，請在下方評論，我會繼續跟進。

在您專案的所有形式的 Activated 和 Load 事件上嘗試此代碼。
例如，MainForm：
private void MainForm_Activated(object sender, EventArgs e)
{
ApplyTheme();
}
更新：在 BaseForm 上嘗試以下行，如果有效，則在所有表單上添加覆寫并更改所有元素的顏色值：
public virtual void ApplyThemeSpecific(ThemeSettings settings)
{
Background = settings.PrimaryColor; //for example
}
更新 2：在所有表單上添加一個檢查主題更改的計時器，當主題更改時，它會更改視覺效果。或者您可以在主題更改時舉辦活動。
