[研究]ASP.NET,WebForm,用 OdsReaderWriter + DotNetZip (Ionic.Zip) 1.16.0 匯入 .ods
2024-03-29
環境：Visual Studio 2022 + ASP.NET + WebForm + Web Application + C# + SQL Server 2019 + SQL Server Management Studio (SSMS) 19
********************************************************************************
注意
- OdsReaderWriter.cs 和 template.ods 從下面文章取得
How to Read and Write ODF/ODS Files (OpenDocument Spreadsheets) - CodeProject
https://www.codeproject.com/Articles/38425/How-to-Read-and-Write-ODF-ODS-Files-OpenDocument-2
- OdsReaderWriter.cs 中
//ZipFile templateFile = this.GetZipFile(Assembly.GetExecutingAssembly().GetManifestResourceStream("OdsReadWrite.template.ods"));
改成
ZipFile templateFile = this.GetZipFile(File.OpenRead(HttpContext.Current.Server.MapPath("/template.ods")));
- NuGet 要安裝 DotNetZip，要 using
using Ionic.Zip; // Ionic.Zip 被 DotNetZip 取代，NuGet 安裝 DotNetZip，但是 using 還是用舊名稱 Ionic.Zip
- Web.Config 中暫時存放路徑，要手動建立好。

實際測試可以成功匯入。
