推荐答案

您需要打包文件并将结果写入响应。
您可以使用 SharpZipLib 压缩库。

You need to pack files and write a result to a response. You can use SharpZipLib compression library.

代码示例：

Response.AddHeader("Content-Disposition", "attachment; filename=" + compressedFileName + ".zip");
Response.ContentType = "application/zip";

using (var zipStream = new ZipOutputStream(Response.OutputStream))
{
    foreach (string filePath in filePaths)
    {
        byte[] fileBytes = System.IO.File.ReadAllBytes(filePath);

        var fileEntry = new ZipEntry(Path.GetFileName(filePath))
        {
            Size = fileBytes.Length
        };

        zipStream.PutNextEntry(fileEntry);
        zipStream.Write(fileBytes, 0, fileBytes.Length);
    }

    zipStream.Flush();
    zipStream.Close();
}
