Question

我编写了一个使用Epplus创建非常简单的Excel文件的应用程序（五列，唯一的特殊格式是粗体标题列）。然后由其他人移动该文件，并将其导入单独的系统，但该文件无法导入。我找出了失败的原因，这是因为Excel文件在workbook.xml中指定了绝对路径。 Excel的文件验证程序警告此问题，并告诉Excel从文件的标记中删除绝对路径可以解决问题。

有谁知道如何确保Epplus没有添加文件的文件绝对路径？这是我的代码：

using (var pkg = new ExcelPackage(new FileInfo(path))) // "path" is an absolute path to a directory on a shared drive
{
     var sheet = pkg.Workbook.Worksheets.Add("Manifest");
     var w = new ExcelWriter<ManifestLine>(sheet);

     // ... Write data ...

     await w.CloseAsync(Token).ConfigureAwait(false);
     pkg.Save();
}

这是工作簿的标记:(需要删除absPath）

<x:workbook xmlns:x15ac="http://schemas.microsoft.com/office/spreadsheetml/2010/11/ac" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:x15="http://schemas.microsoft.com/office/spreadsheetml/2010/11/main" mc:Ignorable="x15" xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">

          <x15ac:absPath xmlns:x15ac="http://schemas.microsoft.com/office/spreadsheetml/2010/11/ac" url="Y:\ABC\Manifests\" />
        </mc:Choice>
      </mc:AlternateContent>
      <x:bookViews>
        <x:workbookView xWindow="0" yWindow="0" windowWidth="19065" windowHeight="9660" />
      </x:bookViews>
      <x:sheets>
        <x:sheet name="Manifest" sheetId="1" r:id="rId1" />
      </x:sheets>
      <x:calcPr calcId="0" />
    </x:workbook>

谢谢！

这不作为评论工作，所以我在没有测试的情况下发布答案（因为我无法测试）：

// Save current dir before changing directories
var currentDir = Directory.GetCurrentDirectory();

// Change to directory where the file is
Directory.ChangeDirectory(Path.GetDirectoryName(path));

// Pass in *only* the filename, not the whole path
// Because we changed to that file's directory the rest of the code should find it without needing the whole path
using (var pkg = new ExcelPackage(new FileInfo(Path.GetFilename(path))))
{
     var sheet = pkg.Workbook.Worksheets.Add("Manifest");
     var w = new ExcelWriter<ManifestLine>(sheet);

     // ... Write data ...

     await w.CloseAsync(Token).ConfigureAwait(false);
     pkg.Save();
}

Directory.ChangeDirectory(currentDir);  // Change back to whatever directory the program was in before all this.
