NPOI寫Excel，Spire.XLS for.NET元件轉換Excel為PDF
首先要引用NPOI動態庫和Microsoft.Office.Interop.excel.dll （Microsoft.Office.Interop.excel.dll 最好使用使用NuGet下載 ，或者使用網上下載，網上下載以後解壓檔案，把Microsoft.Office.Interop.excel.dll拷貝到專案下，新增引用，而NuGet下載直接引用，不需要再新增引用了，建議NuGet下載。
NPOI的新增則專案選中右鍵使用管理NuGet管理程式包，nuget新增NPOI即可）
上述工作完成，下面直接程式碼
