很久没有更新博客了，本想着直接发一篇《手撕ERP》系列，从控件重写、重绘，到框架搭建，再到部分模块实现+业务的。但是每次动手的时候，都觉得难以下手。直接从数据库设计开始吧，模块设计还没定下来，从模块设计开始吧，winform自带控件和DevExpress控件用起来布局实在太难看了。算了，从低做起吧。接着6-7年前的玩转控件系列开始，工欲善其事必先利其器！利器备好，框架搭建完毕，模块设计就是拖控件而已！
Talk is Cheap,Show me the Code!
首先，项目中新建一个窗体（用于后面的弹窗载体），按自己意愿做好布局效果，当然关于皮肤方面，大家可以应用界内很成熟的皮肤控件（具体就不列举了，避免打广告的嫌疑），或者后期自己代码实现。本篇主要介绍如何重写/重绘控件，磨自己的利器，至于利器上贴个动漫图片还是其他花里胡哨的图案，请根据自己的喜好来。大概效果如图（有洁癖的请自己细心布局）：
窗体后台代码分析如下：
首先窗体集成DevExpress：
public partial class frm_MessageBox : DevExpress.XtraEditors.XtraForm
其余初始化动作代码如下，备注很详细就不一一列举了：
////// 确定按钮 /// private SimpleButton btn_OK; /// /// 取消按钮 /// private SimpleButton btn_Cancel; /// /// 中止按钮 /// private SimpleButton btn_Abort; /// /// 重试按钮 /// private SimpleButton btn_Retry; /// /// 忽略按钮 /// private SimpleButton btn_Ignore; /// /// 是按钮 /// private SimpleButton btn_Yes; /// /// 否按钮 /// private SimpleButton btn_No; /// /// 要在消息框中显示的文本 /// private string text; /// /// 要在消息框的标题栏中显示的文本 /// private string caption; /// /// System.Windows.Forms.MessageBoxButtons 值之一，可指定在消息框中显示哪些按钮 /// private MessageBoxButtons buttons; /// /// System.Windows.Forms.MessageBoxIcon 值之一，它指定在消息框中显示哪个图标 /// private MessageBoxIcon icon; /// /// System.Windows.Forms.MessageBoxDefaultButton 值之一，可指定消息框中的默认按钮。 /// private MessageBoxDefaultButton defaultButton; /// /// 消息弹出框参数实体 /// MessageBoxModel _MessageBoxModel = default(MessageBoxModel);
界面初始化：
////// 支持修改弹出框的按钮标题描述 /// /// public frm_MessageBox(MessageBoxModel pMessageBoxModel) { InitializeComponent(); if (pMessageBoxModel == null) pMessageBoxModel = new MessageBoxModel(); this.ControlBox = false; this.text = pMessageBoxModel.MsgText; this.Text = pMessageBoxModel.FormText ?? "Stephen's UserControl"; this.caption = pMessageBoxModel.FormText; this.buttons = pMessageBoxModel.MsgButton; this.icon = pMessageBoxModel.MsgIcon; this.defaultButton = pMessageBoxModel.MsgxDefaultButton; this._MessageBoxModel = pMessageBoxModel; } /// /// 显示一个具有指定文本、标题、按钮、图标、默认按钮的消息框 /// /// /// /// /// /// public frm_MessageBox(string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton) { InitializeComponent(); this.ControlBox = false; this.text = text; this.Text = caption ?? "Stephen's UserControl"; this.caption = caption; this.buttons = buttons; this.icon = icon; this.defaultButton = defaultButton; }
窗体Load事件绑定弹窗按钮事件：
private void frm_MessageBox_Load(object sender, EventArgs e) { int pannelLength = panelButton.Size.Width; switch (buttons) { case MessageBoxButtons.OK: #region OK this.btn_OK = new SimpleButton(); this.panelButton.SuspendLayout();

代码比较简单，就是把初始化按钮事件和把初始化的弹窗中的按钮添加到布局中的Panel容器里面和一些细节调整，关于方法sysClass.ssLoadMsgOrDefault目前可以不用在意，是我的通用类库，主要是用来实现国际化的，后续会断断续续为大家介绍这块代码。
按钮绑定事件和键盘响应事件代码如下：
private void PaintIcon(Icon icon, int x, int y) { Graphics g = this.CreateGraphics(); 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); } }
以及弹窗实体类：
////// 弹出框实体 /// public class MessageBoxModel { /// /// 弹出框标题 /// public string FormText { get; set; } /// /// 弹出框宽度 /// public int FormWidth { get; set; } /// /// 弹出框高度 /// public int FormHeight { get; set; } /// /// 弹出框消息内容 /// public string MsgText { get; set; } /// /// 文字大小 /// public int FontSize { get; set; } /// /// “是”按钮标题 /// public string YesButtonText { get; set; } /// /// “否”按钮标题 /// public string NoButtonText { get; set; } /// /// “取消”按钮标题 /// public string CancleButtonText { get; set; } /// /// 弹出框类型（提示型、选择型等） /// public MessageBoxButtons MsgButton = MessageBoxButtons.OK; /// /// 弹出框中显示的图标 /// public MessageBoxIcon MsgIcon = MessageBoxIcon.Information; /// /// 弹出框默认选中的按钮 /// public MessageBoxDefaultButton MsgxDefaultButton = MessageBoxDefaultButton.Button1;
细心的读者会发现，博主在实例弹窗实体的时候，有个语法糖：
////// 消息弹出框参数实体 /// MessageBoxModel _MessageBoxModel = default(MessageBoxModel);
default(T) 这是C# 7.1的关键字新用法，主要用法是默认值表达式，default对应各种类型生成默认值列表如下：
罗列一下上述列表中常见类型对应的值
default(string) // null default(int) // 0 default(int?) // null default(dynamic) // null default(DateTime) // 0001/01/01 0:00:00 default(DateTime?) // null
篇幅有限，具体深入了解请大家自行百度看看微软文档的解释。
以上是窗体代码解析，窗体创建好了，最后一步，创建一个实体类(暂时命名KzxMessageBox)用来调用弹窗的窗体显示，具体代码如下：
public class KzxMessageBox { ////// 标题 /// private static string caption; /// /// 按钮(默认“OK”) /// private static MessageBoxButtons buttons; /// /// 图标(默认“information”) /// private static MessageBoxIcon icon; /// /// 默认按钮（默认“button1”） /// private static MessageBoxDefaultButton defaultButton; /// /// 静态构造函数，初始化数据 /// 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; } /// /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框 /// /// 文本 /// public static DialogResult Show(string text) { return Show(text, buttons, icon, defaultButton, null); } /// /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框，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); } /// /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框 /// /// /// /// public static DialogResult Show(string text, Form parent) { return Show(text, buttons, icon, defaultButton, parent); } /// /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框 /// /// 文本 /// 按钮 /// public static DialogResult Show(string text, MessageBoxButtons buttons) { return Show(text, buttons, icon, defaultButton, null); } /// /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框 /// /// /// /// /// public static DialogResult Show(string text, MessageBoxButtons buttons, Form parent) { return Show(text, buttons, icon, defaultButton, parent); } /// /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框 /// /// 文本 /// 标题 /// 按钮 /// 图标 /// public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon) { return Show(text, buttons, icon, defaultButton, null); } /// /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框 /// /// /// /// /// /// public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, Form parent) { return Show(text, buttons, icon, defaultButton, parent); } /// /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框 /// /// /// /// /// /// public static DialogResult Show(string text, MessageBoxButtons buttons, MessageBoxIcon icon, MessageBoxDefaultButton defaultButton) { return Show(text, buttons, icon, defaultButton, null); } /// /// 显示具有指定文本、标题、按钮、图标和默认按钮的消息框 /// /// 文本 /// 标题 /// 按钮 /// 图标 /// 默认按钮 /// 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); } } } }
代码比较简单，创建一个公共类，以及类型Messagebox的方法重载而已！
最后一步，调用：
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：
最后，由于后续所有重写/重绘控件都在同一个项目使用，而且Dev系统引用文件较多，压缩后源码文件仍然很大，如果有需要源码的朋友，可以微信公众号联系博主，源码可以免费赠予~！有疑问的也可以CALL我一起探讨，最最后，如果觉得本篇博文对您或者身边朋友有帮助的，麻烦点个关注！赠人玫瑰，手留余香，您的支持就是我写作最大的动力，感谢您的关注，期待和您一起探讨！再会！
