遇到安卓手機解壓縮文件損壞問題時,可以考慮兩種解決方案,方案一是使用SharpCompress庫,它是一個開源項目,能夠提供強大的壓縮與解壓功能,支持多種文件格式,方案二是采用aspose.zip庫,這兩種方法都能有效解決文件損壞的問題

using Aspose.Words;
using Aspose.Words.Saving;
using System.IO.Compression;
namespace ConsoleApp4
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var html = GetHtml();
            using var memoryStream = new MemoryStream();
            using var zipArchive = new ZipArchive(memoryStream, ZipArchiveMode.Create, true);
            var now = DateTime.Now.ToString("yyyy_MM_dd_HH_mm_ss");
            for (int i = 0; i < 3; i++)
            {
                var docPath = now + "_" + i + ".docx";
                var entry = zipArchive.CreateEntry(docPath, System.IO.Compression.CompressionLevel.Fastest);
                using var entryStream = entry.Open();
                var bytes = Html2Word(html);
                var stream = new MemoryStream(bytes);
                stream.CopyTo(entryStream);
            }
            memoryStream.Position = 0;
            // 創(chuàng)建一個FileStream，并將MemoryStream的內(nèi)容寫入該文件  
            string filePath = now + ".zip";
            using (FileStream fileStream = new FileStream(filePath, FileMode.Create, FileAccess.Write))
            {
                memoryStream.CopyTo(fileStream);
            }
            //如果是asp.net core接口返回，代碼如下
            //return File(memoryStream, "application/zip", filePath);
            Console.WriteLine("壓縮完成");
            Console.ReadKey();
        }
        /// <summary>
        /// 獲取html代碼
        /// </summary>
        /// <returns></returns>
        static string GetHtml()
        {
            var htmlData = @"

            return htmlData;
        }
        static byte[] Html2Word(string htmlContent)
        {
            //如果有正版授權(quán)請寫入
            //var memoryStream = new MemoryStream(Convert.FromBase64String(""));
            //var license = new Aspose.Words.License();
            //license.SetLicense(memoryStream);
            var doc = new Aspose.Words.Document();
            doc.RemoveAllChildren();
            Aspose.Words.DocumentBuilder builder = new DocumentBuilder(doc);
            builder.InsertHtml(htmlContent);

            doc.Save(resultMemoryStream, SaveOptions.CreateSaveOptions(SaveFormat.Docx));
            return  resultMemoryStream.ToArray();
        }
    }
}

安卓手機解壓縮出現(xiàn)損壞的問題

方案1 使用SharpCompress

using Aspose.Words;
using Aspose.Words.Saving;
using SharpCompress.Archives.Zip;
using System;
using System.IO;
namespace ZipStu02
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var html = GetHtml();
            var now = DateTime.Now.ToString("yyyy_MM_dd_HH_mm_ss");
            var archive = ZipArchive.Create();
            for (int i = 0; i < 3; i++)
            {
                var docName = now + "_" + i + ".docx";
                var bytes = Html2Word(html);
                var stream = new MemoryStream(bytes);
                archive.AddEntry(docName, stream);
            }
            string filePath = now + ".zip";
            using (FileStream fileStream = new FileStream(filePath, FileMode.Create, FileAccess.Write))
            {
                archive.SaveTo(fileStream);
            }
            Console.WriteLine("生成成功");
            Console.ReadKey();
        }
    }
}

方案2 使用aspose.zip

//var license = new Aspose.Zip.License();
//license.SetLicense("Aspose.Total.lic");
var html = GetHtml();
//Html2Word(html);
var now = DateTime.Now.ToString("yyyy_MM_dd_HH_mm_ss");
var archive = new Archive();
for (int i = 0; i < 3; i++)
{
    var docName = now + "_" + i + ".docx";
    var bytes = Html2Word(html);
    var stream = new MemoryStream(bytes);
    archive.CreateEntry(docName, stream);
}
string filePath = now + ".zip";
using (FileStream fileStream = new FileStream(filePath, FileMode.Create, FileAccess.Write))
{
    archive.Save(fileStream);
}
Console.WriteLine("生成成功");
Console.ReadKey();
