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元件，于是就有了本系列文章，

如果覺得寫的還行，請點個 star 支持一下吧

用處及效果
準備作業
這個用到了基類表單 （十七）c#Winform自定義控制元件-基類表單 ，如果不了解可以先移步看一下
開始
添加一個表單FrmLoading 繼承 FrmBase
東西不多，看全部代碼

說明：
BackgroundWorkAction：加載資源任務函式
CurrentMsg：當前需要顯示的進度資訊，key:任務進度，取值0-100 value：當前任務名稱
BindingProcessMsg：向界面系結資料，子類需要重寫此函式來實作向界面系結顯示資料
示例：
添加一個表單FrmTestLoading 繼承FrmLoading
添加一個文本label1顯示進度資訊文字
添加一個進度條ucProcessLineExt1顯示進度值
重新BindingProcessMsg系結資訊
1 protected override void BindingProcessMsg(string strText, int intValue)2 {3 label1.Text = strText;4 this.ucProcessLineExt1.Value =https://www.cnblogs.com/bfyx/p/ intValue;5 }
