1.問題描述

採用:Ionic.Zip.dll的方法

zipFile.Save(ZIPFile); 卡死,無反應,

問題是某些文件在一起時,壓縮卡死,文件單獨壓縮又沒有問題,,具體原因未知

解決方案:換其他的DLL如ICSharpCode.SharpZipLib方法,Ionic.Zip.dll的方法為找有效的方式

Ionic.Zip代碼如下

/// <summary>
            /// 文件壓縮 ,小概率事件zipFile.Save 卡死
            /// </summary>
            /// <param name="files"></param>
            /// <param name="ZIPFile"></param>
            public void OldZIP(string[] files, string ZIPFile)
            {
                try
                {
                    using (Ionic.Zip.ZipFile zipFile = new Ionic.Zip.ZipFile(System.Text.Encoding.UTF8))
                    {
                        for (int i = 0; i < files.Length; i++)
                        {
                            string path = files[i];
                            using (System.IO.FileStream fileStream = new System.IO.FileStream(path, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite))
                            {
                                byte[] array = new byte[fileStream.Length];
                                fileStream.Read(array, 0, array.Length);
                                string fileName = System.IO.Path.GetFileName(path);
                                zipFile.AddEntry(fileName, array);
                            }
                        }
                        zipFile.Save(ZIPFile);
                    }
    
                    // 以下壓縮,中文字出現亂碼,沒出現之前的卡死現象
                    //using (System.IO.FileStream fStream = System.IO.File.Create(ZIPFile))
                    //{
                    //    using (Ionic.Zip.ZipOutputStream zipStream = new Ionic.Zip.ZipOutputStream(fStream))
                    //    {
                    //        for (int i = 0; i < files.Length; i++)
                    //        {
                    //            string path = files[i];
                    //            using (System.IO.FileStream fileStream = new System.IO.FileStream(path, System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite))
                    //            {
                    //                byte[] array = new byte[fileStream.Length];
                    //                fileStream.Read(array, 0, array.Length);
                    //                string fileName = System.IO.Path.GetFileName(path);
                    //                fileStream.Close();
                    //                byte[] filbyte = System.Text.Encoding.UTF8.GetBytes(fileName);
                    //                zipStream.PutNextEntry(System.Text.Encoding.UTF8.GetString(filbyte));
    
                    //                zipStream.Write(array, 0, array.Length);
                    //            }
                    //        }
                    //    }
                    //}
                }
                catch (System.Exception innerException)
                {
                    throw new System.Exception("Error zipping folder ", innerException);
                }
            }

換用ICSharpCode.SharpZipLib的方法如下

/// <summary>
            ///  文件壓縮
            /// </summary>
            /// <param name="files">文件集合</param>
            /// <param name="ZIPFile">壓縮文件名稱</param>
            public static void ZIP(string[] files, string ZIPFile)
            {
                try
                {
                    ICSharpCode.SharpZipLib.Checksums.Crc32 crc = new ICSharpCode.SharpZipLib.Checksums.Crc32();
    
                    using (System.IO.FileStream fStream = System.IO.File.Create(ZIPFile))
                    {
                        using (ICSharpCode.SharpZipLib.Zip.ZipOutputStream zipStream = new ICSharpCode.SharpZipLib.Zip.ZipOutputStream(fStream))
                        {
                            for (int i = 0; i < files.Length; i++)
                            {
                                string FileToZip = files[i];
                                using (FileStream fs = File.OpenRead(FileToZip))
                                {
                                    byte[] buffer = new byte[fs.Length];
                                    fs.Read(buffer, 0, buffer.Length);
                                    string fileName = System.IO.Path.GetFileName(FileToZip);
                                    ICSharpCode.SharpZipLib.Zip.ZipEntry entry = new ICSharpCode.SharpZipLib.Zip.ZipEntry(fileName);
                                    entry.DateTime = DateTime.Now;
                                    entry.Size = fs.Length;
                                    fs.Close();
                                    crc.Reset();
                                    crc.Update(buffer);
                                    entry.Crc = crc.Value;
                                    zipStream.PutNextEntry(entry);
                                    zipStream.Write(buffer, 0, buffer.Length);
                                }
                            }
                        }
                    }
                }
                catch (System.Exception innerException)
                {
                    throw new System.Exception("Error zipping folder ", innerException);
                }
            }
