遇到安卓手機(jī)解壓縮文件損壞問(wèn)題時(shí),可以考慮兩種解決方案,方案一是使用SharpCompress庫(kù),它是一個(gè)開(kāi)源項(xiàng)目,能夠提供強(qiáng)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(kù),這兩種方法都能有效解決文件損壞的問(wèn)題

安卓手機(jī)解壓縮出現(xiàn)損壞的問(wèn)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();
