前提

入行已經7,8年了，一直想做一套漂亮點的自定義控制項，於是就有了本系列文章。

開源地址：https://gitee.com/kwwwvagaa/net_winform_custom_control

如果覺得寫的還行，請點個 star 支持一下吧

歡迎前來交流探討：企鵝群568015492

準備工作

這是一個提示消息的窗體，他繼承自基類窗體FrmBase，如果你對FrmBase還不瞭解，請移步（十七）c#Winform自定義控制項-基類窗體查看

提示消息窗體支持有確定取消按鈕及單取消按鈕，更多操作按鈕暫沒有增加

開始

添加一個Form命名為FrmDialog ，繼承FrmBase

私有的構造函數

 1  private FrmDialog(
 2             string strMessage,
 3             string strTitle,
 4             bool blnShowCancel = false,
 5             bool blnShowClose = false,
 6             bool blnisEnterClose = true)
 7         {
 8             InitializeComponent();
 9             if (!string.IsNullOrWhiteSpace(strTitle))
10                 lblTitle.Text = strTitle;
11             lblMsg.Text = strMessage;
12             if (blnShowCancel)
13             {
14                 this.tableLayoutPanel1.ColumnStyles[1].Width = 1;
15                 this.tableLayoutPanel1.ColumnStyles[2].Width = 50;
16             }
17             else
18             {
19                 this.tableLayoutPanel1.ColumnStyles[1].Width = 0;
20                 this.tableLayoutPanel1.ColumnStyles[2].Width = 0;
21             }
22             btnClose.Visible = blnShowClose;
23             blnEnterClose = blnisEnterClose;
24         }

搭配一個靜態的公共函數
