需求：选择一个Excel文件，然后对该Excel文件进行处理，再导出一个处理后的Excel文件。
效果图
声明：我对winform开发不熟，但是我看到许多开发人员做东西只管交差，从不考虑用户体验，也不考虑容错处理，我就在想，难道就不能做得专业一点吗？当你用别人做的东西，满口吐槽的时候有没有想过别人用你做的东西的时候，会不会一样的狂喷呢？
这里对Excel的操作使用了NPOI.dll组件，可自行去网上现在或者使用NuGet下载。
界面皮肤
IrisSkin4.dll包括(73皮肤+vs2012兼容) 绿色版下载地址：http://pan.baidu.com/s/1eQ1sAUA
这里使用到了IrisSkin4.dll皮肤控件
使用方法：
1、添加IrisSkin4.dll引用
1、工具箱，添加此程序集
2、复制皮肤文件
设置皮肤文件的属性
3、代码调用
public frmMain(){InitializeComponent();//加载皮肤 skinEngine1.SkinFile ="Skins/Warm.ssk";skinEngine1.Active = true;skinEngine1.SkinDialogs = false;
//如果要让某个控件不使用皮肤，则设置此属性，这样，就可以单独为此控件设置属性了，否则为此控件设置的属性将会被皮肤属性覆盖lblShow.Tag = skinEngine1.DisableTag;lblMsg.Tag = skinEngine1.DisableTag;this.lblShow.ForeColor = Color.Red;this.lblMsg.ForeColor = Color.Green;}
关于excel的操作，这里还是使用NPOI.dll，可以自己从网上下载，也可以直接从vs的NuGet中下载。
需要注意的是，对于一些比较耗时的界面操作，建议使用一个进度条，然后以异步调用的形式进行操作。异步调用可以开启一个线程，如果在线程调用的代码中需要修改窗体控件，也就是要修改主线程的内容，可以使用如下代码：
Invoke(new MethodInvoker(delegate { progressBar.Maximum = sheet.LastRowNum; }));}
代码很简单，这里我不做过多的说明，详情请参见代码。
