C# Excel處理工具

需求：選擇一個Excel文件，而後對該Excel文件進行處理，再導出一個處理後的Excel文件。

效果圖

 

聲明：我對winform開發不熟，可是我看到許多開發人員作東西只管交差，從不考慮用戶體驗，也不考慮容錯處理，我就在想，難道就不能作得專業一點嗎？當你用別人作的東西，滿口吐槽的時候有沒有想過別人用你作的東西的時候，會不會同樣的狂噴呢？

這裏對Excel的操做使用了NPOI.dll組件，可自行去網上如今或者使用NuGet下載。

界面皮膚

IrisSkin4.dll包括(73皮膚+vs2012兼容) 綠色版下載地址：http://pan.baidu.com/s/1eQ1sAUA

這裏使用到了IrisSkin4.dll皮膚控件

使用方法：

一、添加IrisSkin4.dll引用

一、工具箱，添加此程序集

 

 

二、複製皮膚文件

 

設置皮膚文件的屬性

三、代碼調用

        public frmMain()
        {
            InitializeComponent();
            //加載皮膚              
            skinEngine1.SkinFile ="Skins/Warm.ssk";
            skinEngine1.Active = true;
            skinEngine1.SkinDialogs = false;
            //若是要讓某個控件不使用皮膚，則設置此屬性，這樣，就能夠單獨爲此控件設置屬性了，不然爲此控件設置的屬性將會被皮膚屬性覆蓋
            lblShow.Tag = skinEngine1.DisableTag;
            lblMsg.Tag = skinEngine1.DisableTag;
            this.lblShow.ForeColor = Color.Red;
            this.lblMsg.ForeColor = Color.Green;
        }

關於excel的操做，這裏仍是使用NPOI.dll，能夠本身從網上下載，也能夠直接從vs的NuGet中下載。

須要注意的是，對於一些比較耗時的界面操做，建議使用一個進度條，而後以異步調用的形式進行操做。異步調用能夠開啓一個線程，若是在線程調用的代碼中須要修改窗體控件，也就是要修改主線程的內容，可使用以下代碼：

  Invoke(new MethodInvoker(delegate { progressBar.Maximum = sheet.LastRowNum; }));}

代碼很簡單，這裏我不作過多的說明，詳情請參見代碼。
