[英]C# create zip file using zip archive System.IO.Compression
Here is the functionality I want to achieve 这是我想要实现的功能
I am using the System.IO.Compression ZipArchive to achieve this. 我正在使用System.IO.Compression ZipArchive来实现这一目标。 From the documentation, I have not found a good use case for this.
从文档中,我没有找到一个很好的用例。 The examples in documentation assume that the zip file exists.
文档中的示例假定zip文件存在。
What I want to do Create zipArchive stream write JSON file and pdf file as entries in the zip file. 我想做什么创建zipArchive流将JSON文件和pdf文件写为zip文件中的条目。
using (var stream = new FileStream(path, FileMode.Create))
{
using (var archive = new ZipArchive(stream, ZipArchiveMode.Create, true))
{
ZipArchiveEntry manifest = archive.CreateEntry(filenameManifest);
using (StreamWriter writerManifest = new StreamWriter(manifest.Open()))
{
writerManifest.WriteLine(JSONObject_String);
}
ZipArchiveEntry pdfFile = archive.CreateEntry(filenameManifest);
using (StreamWriter writerPDF = new StreamWriter(pdfFile.Open()))
{
writerPDF.WriteLine(pdf);
}
}
}
You don't close the stream
, you open with ' manifest.Open()
'. 你没有关闭
stream
,你打开' manifest.Open()
'。 Then it might not have written everything to the zip. 然后它可能没有写入zip的所有内容。
Wrap it in another using
, like this: 用另一种
using
包装它,如下所示:
using (var stream = new FileStream(path, FileMode.Create))
{
using (var archive = new ZipArchive(stream, ZipArchiveMode.Create, true))
{
ZipArchiveEntry manifest = archive.CreateEntry(filenameManifest);
using (Stream st = manifest.Open())
{
using (StreamWriter writerManifest = new StreamWriter(st))
{
writerManifest.WriteLine(JSONObject_String);
}
}
ZipArchiveEntry pdfFile = archive.CreateEntry(filenameManifest);
using (Stream st = manifest.Open())
{
using (StreamWriter writerPDF = new StreamWriter(st))
{
writerPDF.WriteLine(pdf);
}
}
}
}
