.net ZipFile类：如何修改存档中的文本文件？

Question

有人知道如何使用.net的ZipFile类修改zip归档文件中的文本文件吗？我的意思是没有解压缩所有内容，而是再次进行修改和压缩。到目前为止，读取文件很容易：

using (var zip = ZipFile.Open("ExcelWorkbookWithMacros.xlsm", ZipArchiveMode.Update))
{
    var entry = zip.GetEntry("xl/_rels/workbook.xml.rels");
    if (entry != null)
    {
        var tempFile = Path.GetTempFileName();
        entry.ExtractToFile(tempFile, true);
        var content = File.ReadAllText(tempFile);

        content = content.Replace("xxx", ""); // THIS IS WHAT I NEED TO DO

    }
}

无需解压缩文件。您可以这样做：

string entryName = "some entry";
string contents = "";
var entry = zip.GetEntry(entryName);
if (entry != null)
{
  using(StreamReader streamReader = new StreamReader(entry.Open()))
  {
    contents = streamReader.ReadToEnd();
  }

  contents = contents.Replace("xxx", "");
  entry.Delete();
  entry = zip.CreateEntry(entryName);

  using(StreamWriter streamWriter = new StreamWriter(entry.Open()))
  {
    streamWriter.Write(contents);
  }
}
