C#生成ZIP压缩包
生成ZIP压缩包C#代码如下:
using System; using System.Collections.Generic; using System.Text; using ICSharpCode.SharpZipLib; using ICSharpCode.SharpZipLib.Checksums; using ICSharpCode.SharpZipLib.Zip; using System.IO; using log4net; using log4net.Config; namespace Test.BLL { public class TestZipFile { protected static readonly ILog logger = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); ///<summary> /// 创建ZIP文件 ///</summary> public void CreateZipFile(string[] files, string sTempFile, string sPassWord) { try { using (ZipOutputStream s = new ZipOutputStream(File.Create(sTempFile))) { s.SetLevel(9); // 压缩级别 0-9 if (sPassWord != "") { s.Password = sPassWord; //Zip压缩文件密码 } byte[] buffer = new byte[4096]; //缓冲区大小 foreach (string file in files) { if (!string.IsNullOrEmpty(file)) { if (File.Exists(file)) { ZipEntry entry = new ZipEntry(Path.GetFileName(file)); entry.DateTime = DateTime.Now; s.PutNextEntry(entry); using (FileStream fs = File.OpenRead(file)) { int sourceBytes; do { sourceBytes = fs.Read(buffer, 0, buffer.Length); s.Write(buffer, 0, sourceBytes); } while (sourceBytes > 0); } } else { logger.Error("文件:" + file + "不存在。"); } } } s.Finish(); s.Close(); } } catch (Exception ex) { logger.Error("压缩文件时异常!"); logger.Error("异常描述:\t" + ex.Message); logger.Error("异常方法:\t" + ex.TargetSite); logger.Error("异常堆栈:\t" + ex.StackTrace); } } /// <summary> /// /// </summary> /// <param name="files">放入ZIP的文件路劲(含文件名)</param> /// <param name="sTempFile">创建的ZIP文件路劲(含文件名)</param> /// <param name="sPassWord">ZIP文件密码</param> /// <param name="folderNames">存放到ZIP中的文件夹名,空代表放在顶级目录</param> public void CreateZipFileMutilFolder(string[] files, string sTempFile, string sPassWord, string[] folderNames) { try { using (ZipOutputStream s = new ZipOutputStream(File.Create(sTempFile))) { s.SetLevel(9); // 压缩级别 0-9 if (sPassWord != "") { s.Password = sPassWord; //Zip压缩文件密码 } byte[] buffer = new byte[4096]; //缓冲区大小 int i = 0; foreach (string file in files) { if (!string.IsNullOrEmpty(file)) { if (File.Exists(file)) { ZipEntry entry = new ZipEntry((string.IsNullOrEmpty(folderNames[i]) ? "" : (folderNames[i] + "\\")) + Path.GetFileName(file)); entry.DateTime = DateTime.Now; s.PutNextEntry(entry); using (FileStream fs = File.OpenRead(file)) { int sourceBytes; do { sourceBytes = fs.Read(buffer, 0, buffer.Length); s.Write(buffer, 0, sourceBytes); } while (sourceBytes > 0); } } else { logger.Error("文件:" + file + "不存在。"); } } i++; } s.Finish(); s.Close(); } } catch (Exception ex) { logger.Error("压缩文件时异常!"); logger.Error("异常描述:\t" + ex.Message); logger.Error("异常方法:\t" + ex.TargetSite); logger.Error("异常堆栈:\t" + ex.StackTrace); } } } }
其中会用到的文件名、文件路径非法字符替换方法:
/// <summary> /// Remove invalid characters which are not allowed in the file name /// </summary> /// <param name="fileName"></param> /// <returns></returns> public string RemoveFileNameInvalidChar(string fileName) { if (string.IsNullOrEmpty(fileName)) return fileName; string invalidChars = new string(Path.GetInvalidFileNameChars()); string invalidReStr = string.Format("[{0}]", Regex.Escape(invalidChars)); return Regex.Replace(fileName, invalidReStr, ""); } /// <summary> /// Remove invalid characters which are not allowed in the path names /// </summary> /// <param name="filePath"></param> /// <returns></returns> public string RemovePathInvalidChar(string filePath) { if (string.IsNullOrEmpty(filePath)) return filePath; string invalidChars = new string(Path.GetInvalidPathChars()); string invalidReStr = string.Format("[{0}]", Regex.Escape(invalidChars)); return Regex.Replace(filePath, invalidReStr, ""); }
