在開發中最重要的就是美化form窗口，在開發中，大多都是用會用自主美化的窗口開發程序。

本文只是點多，分為上中下節。分段講解。

本文主要講解窗口美化關鍵步驟。

首先美化窗體，就需要自己繪制最大化 最小化 關閉按鈕。

其次就是界面樣式，標題區域等

這一步很重要，首先要將窗體屬性設置為None。

其次，可以在屬性中將背景顏色調整，本教程是酷黑色，用的值為 37,37,38。可以根據自己需求使用自主值。

public WenForm() { InitializeComponent(); RefreshPadding(); SystemButtonAdd(); base.SetStyle( ControlStyles.UserPaint | ControlStyles.DoubleBuffer | ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint | ControlStyles.ResizeRedraw | ControlStyles.SupportsTransparentBackColor, true); base.UpdateStyles(); //獲取顯示器的工作區。工作區是顯示器的桌面區域，不包括任務欄、停靠窗口和停靠工具欄。 this.MaximizedBounds = Screen.PrimaryScreen.WorkingArea; this.BackColor = Color.FromArgb(37, 37, 38); this.ForeColor = Color.White; }

關鍵構造函數中相關內容，重繪用的最多的就是如上代碼，基本上在重繪中使用很平凡。

private void SystemButtonAdd() { buttonPointX = 0; CloseButtonAdd(); MaxButtonAdd(); MinButtonAdd(); ConfigButtonAdd(); SkinButtonAdd(); }

接下來繪制系統按鈕 ，包含最大化 最小化 關閉 按鈕 ，可以根據自己需求增加按鈕，例如設置按鈕， 皮膚按鈕等，本文教程主要繪制 5個按鈕 ，代碼相近。

#region 添加關閉按鈕 private void CloseButtonAdd() { if (this.Controls["SystemButtonClose"] is WenControl close) { this.Controls.Remove(close); } buttonPointX = buttonPointX + 46; int x = buttonPointX; WenControl wenControl = new WenControl() { BackColor = Color.Transparent, Width = 46, Height = 30, Location = new Point(this.Width - x, 0), Name = "SystemButtonClose" }; wenControl.MouseEnter += (s, e) => { wenControl.BackColor = Color.FromArgb(63, 63, 65); }; wenControl.MouseLeave += (s, e) => { wenControl.BackColor = Color.Transparent; }; wenControl.Paint += (s, e) => { Graphics g = e.Graphics; g.SetGDIHigh(); using Pen p = new Pen(Color.White, 1); g.DrawLine(p, 18, 11, 18 + 8, 11 + 8); g.DrawLine(p, 18, 11 + 8, 18 + 8, 11); }; wenControl.Click += (s, e) => { this.Close(); }; this.SizeChanged += (s, e) => { wenControl.Location = new Point(this.Width - x, 0); }; this.Controls.Add(wenControl); } #endregion

關閉按鈕

#region 添加最大化按鈕 private void MaxButtonAdd() { if (this.Controls["SystemButtonMax"] is WenControl max) { this.Controls.Remove(max); } if (!MaximizeBox) return; buttonPointX = buttonPointX + 46; int x = buttonPointX; WenControl wenControl = new WenControl() { BackColor = Color.Transparent, Width = 46, Height = 30, Location = new Point(this.Width - x, 0), Name = "SystemButtonMax" }; wenControl.MouseEnter += (s, e) => { wenControl.BackColor = Color.FromArgb(63, 63, 65); }; wenControl.MouseLeave += (s, e) => { wenControl.BackColor = Color.Transparent; }; wenControl.Paint += (s, e) => { Graphics g = e.Graphics; g.SetGDIHigh(); using Pen p = new Pen(Color.White, 1); if (this.WindowState == FormWindowState.Maximized) { g.DrawRectangle(p, 18, 11 + 2, 6, 6); g.DrawRectangle(p, 18 + 2, 11, 6, 6); } else { g.DrawRectangle(p, 18, 11, 8, 8); } }; wenControl.Click += (s, e) => { if (WindowState == FormWindowState.Maximized) { this.WindowState = FormWindowState.Normal; } else { this.WindowState = FormWindowState.Maximized; } }; this.SizeChanged += (s, e) => { wenControl.Location = new Point(this.Width - x, 0); }; this.Controls.Add(wenControl); } #endregion

添加最大化按鈕

#region 最小化按鈕 private void MinButtonAdd() { if (this.Controls["SystemButtonMin"] is WenControl min) { this.Controls.Remove(min); } if (!MinimizeBox) return; buttonPointX = buttonPointX + 46; int x = buttonPointX; WenControl wenControl = new WenControl() { BackColor = Color.Transparent, Width = 46, Height = 30, Location = new Point(this.Width - x, 0), Name = "SystemButtonMin" }; wenControl.MouseEnter += (s, e) => { wenControl.BackColor = Color.FromArgb(63, 63, 65); }; wenControl.MouseLeave += (s, e) => { wenControl.BackColor = Color.Transparent; }; wenControl.Paint += (s, e) => { Graphics g = e.Graphics; g.SetGDIHigh(); using Pen p = new Pen(Color.White, 1); g.DrawLine(p, 18, 15, 18 + 8, 15); }; wenControl.Click += (s, e) => { this.WindowState = FormWindowState.Minimized; }; this.SizeChanged += (s, e) => { wenControl.Location = new Point(this.Width - x, 0); }; this.Controls.Add(wenControl); } #endregion

最小化按鈕

#region 設置按鈕 private void ConfigButtonAdd() { if (this.Controls["SystemButtonConfig"] is WenControl c) { this.Controls.Remove(c); } if (!ConfigButtonBox) return; buttonPointX = buttonPointX + 46; int x = buttonPointX; WenControl wenControl = new WenControl() { BackColor = Color.Transparent, Width = 46, Height = 30, Location = new Point(this.Width - x, 0), Name = "SystemButtonConfig" }; wenControl.MouseEnter += (s, e) => { wenControl.BackColor = Color.FromArgb(63, 63, 65); }; wenControl.MouseLeave += (s, e) => { wenControl.BackColor = Color.Transparent; }; wenControl.Paint += (s, e) => { Graphics g = e.Graphics; g.SetGDIHigh(); g.DrawImage(Properties.Resources.setbutton, new Rectangle(13, 5, 20, 20)); }; wenControl.Click += (s, e) => { ConfigButtonClick?.Invoke(this, e); }; this.SizeChanged += (s, e) => { wenControl.Location = new Point(this.Width - x, 0); }; this.Controls.Add(wenControl); } #endregion

設置按鈕

#region 皮膚按鈕 private void SkinButtonAdd() { if (this.Controls["SystemButtonSkin"] is WenControl c) { this.Controls.Remove(c); } if (!SkinButtonBox) return; buttonPointX = buttonPointX + 46; int x = buttonPointX; WenControl wenControl = new WenControl() { BackColor = Color.Transparent, Width = 46, Height = 30, Location = new Point(this.Width - x, 0), Name = "SystemButtonSkin" }; wenControl.MouseEnter += (s, e) => { wenControl.BackColor = Color.FromArgb(63, 63, 65); }; wenControl.MouseLeave += (s, e) => { wenControl.BackColor = Color.Transparent; }; wenControl.Paint += (s, e) => { Graphics g = e.Graphics; g.SetGDIHigh(); g.DrawImage(Properties.Resources.skin, new Rectangle(13, 5, 20, 20)); }; wenControl.Click += (s, e) => { SkinButtonClick?.Invoke(this, e); }; this.SizeChanged += (s, e) => { wenControl.Location = new Point(this.Width - x, 0); }; this.Controls.Add(wenControl); } #endregion

皮膚按鈕

本文中 關閉 ，最大化 ，最小化按鈕用GDI+畫。也可以用圖檔代替。

設置按鈕，和皮膚按鈕，在阿里圖標庫中下載，可以自主下載編輯。
