DirectoryInfo di = new DirectoryInfo(combinedPath); if (di.Exists) { // 提供 zip 文件的路径和名称以创建字符串 zipFile = folderToZip + "\" + folderGuid + ".zip";
//call the ZipFile.CreateFromDirectory() method
ZipFile.CreateFromDirectory(combinedPath, zipFile, CompressionLevel.Fastest, true);
var result = new HttpResponseMessage(HttpStatusCode.OK);
using (ZipArchive zip = ZipFile.Open(zipFile, ZipArchiveMode.Read))
{
zip.CreateEntryFromFile(folderFiles, "file.zip");
}
var stream = new FileStream(zipFile, FileMode.Open);
result.Content = new StreamContent(stream);
