ICSharpCode.SharpZipLibvalidationzip文件

对C＃使用ICSharpCode.SharpZipLib，如何validation传递的文件实际上是一个有效的zip文件（不是右键单击并重命名为.zip）？

[HttpPost] public ActionResult Upload(HttpPostedFileBase fileData) { if (fileData != null && fileData.ContentLength > 0) { if (Path.GetExtension(fileData.FileName) == ".zip") { var zipFile = Server.MapPath("~/Content/uploads/" + Path.GetFileName(fileData.FileName)); fileData.SaveAs(zipFile); FileStream fs = System.IO.File.OpenRead(zipFile); ZipFile zf = new ZipFile(fs); foreach (ZipEntry zipEntry in zf) { if (zipEntry.Name.EndsWith(".htm") || zipEntry.Name.EndsWith(".html")) { return Json(new { success = true }); } } fs.Close(); fs.Dispose(); System.IO.File.Delete(zipFile); } else { var fileName = Server.MapPath("~/Content/uploads/" + Path.GetFileName(fileData.FileName)); fileData.SaveAs(fileName); return Json(new { success = true }); } } return Json(new { success = false }); }

您可以使用ZipFile.TestArchive方法。 以下是在SharpZipLib声明它的方式：

 /// 
 /// Test an archive for integrity/validity /// 
 /// Perform low level data Crc check /// true if all tests pass, false otherwise /// Testing will terminate on the first error found. public bool TestArchive(bool testData) { return TestArchive(testData, TestStrategy.FindFirstError, null); } 

用法示例：

 ZipFile zipFile = new ZipFile("archive.zip"); Console.WriteLine("Archive validation result: {0}", zipFile.TestArchive(true));

小心这个。 当我立即尝试重命名时，它为我创建了一个IOAccess错误，我不得不添加一个using语句：

 public static bool ValidateZipFile(string fileToTest) { bool result; //Added using statement to fix IOAccess Blocking using (ICSharpCode.SharpZipLib.Zip.ZipFile zip = new ICSharpCode.SharpZipLib.Zip.ZipFile(fileToTest)) { result = zip.TestArchive(true, TestStrategy.FindFirstError, null); } return result; }
