很久沒有更新博客了，本想著直接發一篇《手撕ERP》系列，從控件重寫、重繪，到框架搭建，再到部分模塊實現+業務的。但是每次動手的時候，都覺得難以下手。直接從數據庫設計開始吧，模塊設計還沒定下來，從模塊設計開始吧，winform自帶控件和DevExpress控件用起來布局實在太難看了。算了，從低做起吧。接著6-7年前的玩轉控件系列開始，工欲善其事必先利其器！利器備好，框架搭建完畢，模塊設計就是拖控件而已！Talk is Cheap,Show me the Code!????????首先，項目中新建一個窗體(用于后面的彈窗載體)，按自己意愿做好布局效果，當然關于皮膚方面，大家可以應用界內很成熟的皮膚控件(具體就不列舉了，避免打廣告的嫌疑)，或者后期自己代碼實現。本篇主要介紹如何重寫/重繪控件，磨自己的利器，至于利器上貼個動漫圖片還是其他花里胡哨的圖案，請根據自己的喜好來。大概效果如圖(有潔癖的請自己細心布局)：

窗體后臺代碼分析如下：首先窗體集成DevExpress： public partial class frm_MessageBox : DevExpress.XtraEditors.XtraForm其余初始化動作代碼如下，備注很詳細就不一一列舉了： /// /// 確定按鈕/// private SimpleButton btn_OK;/// /// 取消按鈕/// private SimpleButton btn_Cancel;/// /// 中止按鈕/// private SimpleButton btn_Abort;/// /// 重試按鈕/// private SimpleButton btn_Retry;/// /// 忽略按鈕/// private SimpleButton btn_Ignore;/// /// 是按鈕/// private SimpleButton btn_Yes;/// /// 否按鈕/// private SimpleButton btn_No;/// /// 要在消息框中顯示的文本/// private string text;/// /// 要在消息框的標題欄中顯示的文本/// private string caption;/// /// System.Windows.Forms.MessageBoxButtons 值之一，可指定在消息框中顯示哪些按鈕/// private MessageBoxButtons buttons;/// /// System.Windows.Forms.MessageBoxIcon 值之一，它指定在消息框中顯示哪個圖標/// private MessageBoxIcon icon;/// /// System.Windows.Forms.MessageBoxDefaultButton 值之一，可指定消息框中的默認按鈕。/// private MessageBoxDefaultButton defaultButton;/// /// 消息彈出框參數實體/// MessageBoxModel _MessageBoxModel = default(MessageBoxModel);界面初始化：/// /// 支持修改彈出框的按鈕標題描述/// /// public frm_MessageBox(MessageBoxModel pMessageBoxModel){ InitializeComponent(); if (pMessageBoxModel == null) pMessageBoxModel = new MessageBoxModel(); this.ControlBox = false; this.text = pMessageBoxModel.MsgText; this.Text = pMessageBoxModel.FormText ??

g.DrawIcon(icon, x, y); } void btn_No_Click(object sender, EventArgs e) { this.DialogResult = DialogResult.No; } void btn_Yes_Click(object sender, EventArgs e) { this.DialogResult = DialogResult.Yes; } void btn_Ignore_Click(object sender, EventArgs e) { this.DialogResult = DialogResult.Ignore; } void btn_Retry_Click(object sender, EventArgs e) { this.DialogResult = DialogResult.Retry; } void btn_Abort_Click(object sender, EventArgs e) { this.DialogResult = DialogResult.Abort; } void btn_Cancel_Click(object sender, EventArgs e) { this.DialogResult = DialogResult.Cancel; } void btn_OK_Click(object sender, EventArgs e) { this.DialogResult = DialogResult.OK; } private void frm_MessageBox_KeyUp(object sender, KeyEventArgs e) { if (e.Modifiers == Keys.None) { if (e.KeyCode == Keys.O && btn_OK != null) { btn_OK_Click(null, null); } if (e.KeyCode == Keys.C && btn_Cancel != null) { btn_Cancel_Click(null, null); } if (e.KeyCode == Keys.A && btn_Abort != null) { btn_Abort_Click(null, null); } if (e.KeyCode == Keys.R && btn_Retry != null) { btn_Retry_Click(null, null); } if (e.KeyCode == Keys.I && btn_Ignore != null) { btn_Ignore_Click(null, null); } if (e.KeyCode == Keys.Y && btn_Yes != null) { btn_Yes_Click(null, null); } if (e.KeyCode == Keys.N && btn_No != null) { btn_No_Click(null, null); } } if (e.Modifiers == Keys.Control && e.KeyCode == Keys.C) { string mCopyText = "-------------------------------"; mCopyText += "\n"; mCopyText += lblMsg.Text + "\n"; mCopyText += "-------------------------------"; Clipboard.SetText(mCopyText); } } private void frm_MessageBox_Paint(object sender, PaintEventArgs e) { Icon msgIcon; switch (icon) { case MessageBoxIcon.Error: msgIcon = System.Drawing.SystemIcons.Error; break; case MessageBoxIcon.Question: msgIcon = System.Drawing.SystemIcons.Question; break; case MessageBoxIcon.Exclamation: msgIcon = System.Drawing.SystemIcons.Exclamation; break; default: msgIcon = System.Drawing.SystemIcons.Information; break; } e.Graphics.DrawIcon(msgIcon, 40, 20); }}以及彈窗實體類： /// /// 彈出框實體/// public class MessageBoxModel{ /// /// 彈出框標題 /// public string FormText { get; set; } /// /// 彈出框寬度 /// public int FormWidth { get; set; } /// /// 彈出框高度 /// public int FormHeight { get; set; } /// /// 彈出框消息內容 /// public string MsgText { get; set; } /// /// 文字大小 /// public int FontSize { get; set; } /// /// “是”按鈕標題 /// public string YesButtonText { get; set; } /// /// “否”按鈕標題 /// public string NoButtonText { get; set; } /// /// “取消”按鈕標題 /// public string CancleButtonText { get; set; } /// /// 彈出框類型(提示型、選擇型等) /// public MessageBoxButtons MsgButton = MessageBoxButtons.OK; /// /// 彈出框中顯示的圖標 /// public MessageBoxIcon MsgIcon = MessageBoxIcon.Information; /// /// 彈出框默認選中的按鈕 /// public MessageBoxDefaultButton MsgxDefaultButton = MessageBoxDefaultButton.Button1;細心的讀者會發現，博主在實例彈窗實體的時候，有個語法糖： /// /// 消息彈出框參數實體 /// MessageBoxModel _MessageBoxModel = default(MessageBoxModel);default(T) 這是C# 7.1的關鍵字新用法，主要用法是默認值表達式，default對應各種類型生成默認值列表如下：

類型	默認值
任何引用類型	null
數值類型	0
bool	false
enum	表達式(E)0生成的值，其中E是枚舉標識符
struct	通過如下設置生成的值：將所有值類型的字段設置為其默認值，將所有引用類型的字段設置為null?????
可以為null的類型	HasValue屬性為false且Value屬性未定義的實例

羅列一下上述列表中常見類型對應的值default(string) // nulldefault(int) // 0default(int?) // nulldefault(dynamic) // nulldefault(DateTime) // 0001/01/01 0:00:00default(DateTime?) // null好了，篇幅有限，具體深入了解請大家自行百度看看微軟文檔的解釋。以上是窗體代碼解析，窗體創建好了，最后一步，創建一個實體類(暫時命名KzxMessageBox)用來調用彈窗的窗體顯示，具體代碼如下：public class KzxMessageBox{ /// /// 標題 /// private static string caption; /// /// 按鈕(默認“OK”) /// private static MessageBoxButtons buttons; /// /// 圖標(默認“information”) /// private static MessageBoxIcon icon; /// /// 默認按鈕(默認“button1”) /// private static MessageBoxDefaultButton defaultButton; /// /// 靜態構造函數，初始化數據 /// static KzxMessageBox() { if (SysVar.loginType == 1) { caption = "Stephen's UserControl"; } else { caption = sysClass.ssLoadMsgOrDefault("SYS000008", "Stephen's UserControl"); } buttons = MessageBoxButtons.OK; icon = MessageBoxIcon.Information; defaultButton = MessageBoxDefaultButton.Button1; } /// /// 顯示具有指定文本、標題、按鈕、圖標和默認按鈕的消息框 /// /// 文本 /// public static DialogResult Show(string text) { return Show(text, buttons, icon, defaultButton, null); } /// /// 顯示具有指定文本、標題、按鈕、圖標和默認按鈕的消息框，add by zhang.jz 2019.05.10 /// /// 文本 /// public static DialogResult Show(string text, int pFormWidth = 0, int pFormHeight = 0) { return Show(text, buttons, icon, defaultButton, null, pFormWidth, pFormHeight); } /// /// 顯示具有指定文本、標題、按鈕、圖標和默認按鈕的消息框 /// /// /// /// public static DialogResult Show(string text, Form parent) { return Show(text, buttons, icon, defaultButton, parent); } /// /// 顯示具有指定文本、標題、按鈕、圖標和默認按鈕的消息框 /// /// 文本 /// 按鈕 /// public static DialogResult Show(string text, MessageBoxButtons buttons) { return Show(text, buttons, icon, defaultButton, null); } /// /// 顯示具有指定文本、標題、按鈕、圖標和默認按鈕的消息框 /// /// /// /// /// public static DialogResult Show(string text, MessageBoxButtons buttons, Form parent) { return Show(text, buttons, icon, defaultButton, parent); } /// /// 顯示具有指定文本、標題、按鈕、圖標和默認按鈕的消息框 /// /// 文本 /// 標題 /// 按鈕 /// 圖標 /// public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon) { return Show(text, buttons, icon, defaultButton, null); } /// /// 顯示具有指定文本、標題、按鈕、圖標和默認按鈕的消息框 /// /// /// /// /// /// public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, Form parent) { return Show(text, buttons, icon, defaultButton, parent); } /// /// 顯示具有指定文本、標題、按鈕、圖標和默認按鈕的消息框 /// /// /// /// /// /// public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton) { return Show(text, buttons, icon, defaultButton, null); } /// /// 顯示具有指定文本、標題、按鈕、圖標和默認按鈕的消息框 /// /// 文本 /// 標題 /// 按鈕 /// 圖標 /// 默認按鈕 /// System.Windows.Forms.DialogResult 值之一 public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton, Form parent, int pFormWidth = 0, int pFormHeight = 0) { using (frm_MessageBox frm = new frm_MessageBox(text, caption, buttons, icon, defaultButton)) { if (parent == null || parent.IsDisposed) { frm.StartPosition = FormStartPosition.CenterScreen; if (pFormWidth != 0) frm.Width = pFormWidth; if (pFormHeight != 0) frm.Height = pFormHeight; return frm.ShowDialog(); } else { frm.StartPosition = FormStartPosition.CenterParent; if (pFormWidth != 0) frm.Width = pFormWidth; if (pFormHeight != 0) frm.Height = pFormHeight; return frm.ShowDialog(parent); } } } public static DialogResult Show(Form parent, MessageBoxModel pMessageBoxModel) { using (frm_MessageBox frm = new frm_MessageBox(pMessageBoxModel)) { if (parent == null || parent.IsDisposed) { frm.StartPosition = FormStartPosition.CenterScreen; if (pMessageBoxModel.FormWidth != 0) frm.Width = pMessageBoxModel.FormWidth; if (pMessageBoxModel.FormHeight != 0) frm.Height = pMessageBoxModel.FormHeight; return frm.ShowDialog(); } else { frm.StartPosition = FormStartPosition.CenterParent; if (pMessageBoxModel.FormWidth != 0) frm.Width = pMessageBoxModel.FormWidth; if (pMessageBoxModel.FormHeight != 0) frm.Height = pMessageBoxModel.FormHeight; return frm.ShowDialog(parent); } } }}代碼比較簡單，創建一個公共類，以及類型Messagebox的方法重載而已！最后一步，調用： private void button1_Click(object sender, EventArgs e) { KzxMessageBox.Show("this is a test!"); KzxMessageBox.Show("This is a test!", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1); }一起看下效果：
