我有一个当前进程来提取tar.gz但当前进程无法处理超过4gb ...我想知道我做错了导致我使用sharpzip lib得到错误它说参数长度可以不要少于零......所有注释掉的代码都是当前的过程
请参阅以下代码并给我指示
public static void ExtractTarGZFiles(string strExtractionPath, string strInboundFolder)
{
List<string> files = new List<string>();
string strFile = Path.GetFullPath(ConfigurationManager.AppSettings["InboundFolderPath"].ToString());
if (mblnRunForFile)
{
System.IO.FileInfo ioInfo = new FileInfo(mstrFilename);
strFile = ioInfo.DirectoryName;
files.Add(ioInfo.Name);
}
else
{
files = System.IO.Directory.GetFiles(ConfigurationManager.AppSettings["InboundFolderPath"], "*.gz").ToList();
}
foreach (string file in files)
{
try
{
//string stFilePath = file;
//string testingthisdamnthing = strInboundFolder + mstrFilename;
//FileStream xstream = new FileStream(stFilePath, FileMode.Open, FileAccess.Read, FileShare.None);
//xstream.Close();
//string strTemp = ConfigurationManager.AppSettings["ExtractTempFolderPath"];
//TarArchive objTA = TarArchive.CreateInputTarArchive(new GZipStream(new FileStream(stFilePath, FileMode.Open, FileAccess.Read), CompressionMode.Decompress));
//objTA.ProgressMessageEvent += ExtractTarNotifier;
//objTA.ExtractContents(strTemp);
//DirectoryInfo dirtemp = new DirectoryInfo(strTemp);
DirectoryInfo dirExtract = new DirectoryInfo(strExtractionPath);
Stream inStream = File.OpenRead(stFilePath);
Stream gzipStream = new GZipInputStream(inStream);
TarArchive tarArchive = TarArchive.CreateInputTarArchive(gzipStream);
tarArchive.ExtractContents(ConfigurationManager.AppSettings["ExtractFolderPath"]);
tarArchive.Close();
gzipStream.Close();
inStream.Close();
//while (IsFileExistsinTempPath(dirtemp, dirExtract))
//{
// //Do nothing
//}
//CopyFilesFromTempToExtract(dirtemp, dirExtract);
//objTA.Close();
//Logger.Write(" Tar.Gz files Decompressed Successfully");
MonthLog.Log("Tar.Gz files Decompressed Successfully", "Month", 3, 2, System.Diagnostics.TraceEventType.Information, mstrFilename);
System.IO.File.Copy(stFilePath, ConfigurationManager.AppSettings["ArchiveFolderPath"] + new FileInfo(stFilePath).Name, true);
File.Delete(stFilePath);
//Logger.Write(" Tar.GZ files Moved to Archive Folder");
MonthlyGreenPackageLog.Log("Tar.Gz files Moved to Archive Folder", "Month", 3, 2, System.Diagnostics.TraceEventType.Information, mstrFilename);
}
catch (System.IO.IOException ex)
{
//go to next file
//Logger.Write("Unable to open compressed file");
MonthLog.Log("Unable to open compressed file", "Month", 1, 1, System.Diagnostics.TraceEventType.Error, mstrFilename);

如果你的应用程序是x86，那么每个进程只能有4GB的内存。将其编译为x64以使用更多资源。
答案 1 :(得分：0)
这来自您正在使用的ZipLibrary。您需要将应用程序编译为x64程序并在64位环境中运行。
// To permit the zip to be unpacked by built-in extractor in WinXP and Server2003, WinZip 8, Java, and other older code,
// you need to do one of the following: Specify UseZip64.Off, or set the Size.
// If the file may be bigger than 4GB, or you do not need WinXP built-in compatibility, you do not need either,
// but the zip will be in Zip64 format which not all utilities can understand.

我有三种可能的解决方案，但我无法告诉你这些解决方案是否真的有效。
