我该如何从我的C#控制台应用程序中创建7-Zip档案? 我需要能够使用常规的、广泛可用的7-Zip程序提取这些归档文件。
byte[]。当我将byte[]数组写入文件时，我无法使用7-Zip解压缩它（File.7z不是支持的归档文件）。File.7z不是支持的归档文件）。EggCafe 7Zip Cookie示例 这是一个使用7Zip DLL（动态链接库）进行压缩的示例，可以将cookie（浏览器中存储的信息）进行压缩。
CodePlex 包装器 这是一个开源项目，它封装了7z的压缩功能。
7Zip SDK 官方提供的7zip软件开发工具包（支持C、C++、C#和Java编程语言）。<---我的建议
.Net 压缩库由SharpDevelop.net提供
CodeProject 7zip 示例
SharpZipLib 多种压缩方式
SevenZipSharp 是另一种解决方案。它可以创建7-zip档案...

namespace VHD_Director

{
Int32 dictionary = 1 << 23;
Int32 posStateBits = 2;

bool stdInMode = false;
CoderPropID[] propIDs = {

object[] properties = {

encoder.WriteCoderProperties(outStream);
Int64 fileSize;
if (eos || stdInMode)

byte[] properties = new byte[5];
if (input.Read(properties, 0, 5) != 5)
throw (new Exception("input .lzma is too short"));
decoder.SetDecoderProperties(properties);
long outSize = 0;
for (int i = 0; i < 8; i++)
{
int v = input.ReadByte();
if (v < 0)
throw (new Exception("Can't Read 1"));
outSize |= ((long)(byte)v) << (8 * i);
}
long compressedSize = input.Length - input.Position;
decoder.Code(input, output, compressedSize, outSize, null);

public static void Test()
{
CompressFileLZMA("DiscUtils.pdb", "DiscUtils.pdb.7z");
DecompressFileLZMA("DiscUtils.pdb.7z", "DiscUtils.pdb2");
}
}
}
我使用了SDK。
例如：
using SevenZip.Compression.LZMA;
private static void CompressFileLZMA(string inFile, string outFile)
{
SevenZip.Compression.LZMA.Encoder coder = new SevenZip.Compression.LZMA.Encoder();
using (FileStream input = new FileStream(inFile, FileMode.Open))
{
using (FileStream output = new FileStream(outFile, FileMode.Create))
{
coder.Code(input, output, -1, -1, null);
output.Flush();
}
}
}
string zipfile = @"E:\Folderx\NPPES.zip";
string folder = @"E:\TargetFolderx";
ExtractFile(zipfile,folder);
public void ExtractFile(string source, string destination)
{
// If the directory doesn't exist, create it.
if (!Directory.Exists(destination))
Directory.CreateDirectory(destination);
//string zPath = ConfigurationManager.AppSettings["FileExtactorEXE"];
// string zPath = Properties.Settings.Default.FileExtactorEXE; ;
string zPath=@"C:\Program Files\7-Zip\7zG.exe";
try
{
ProcessStartInfo pro = new ProcessStartInfo();
pro.WindowStyle = ProcessWindowStyle.Hidden;
pro.FileName = zPath;
pro.Arguments = "x \"" + source + "\" -o" + destination;
Process x = Process.Start(pro);
x.WaitForExit();
}
catch (System.Exception Ex) { }
}
只需从源代码安装7 zip并将参数传递给方法即可。
谢谢。请点赞答案。
string PZipPath = @"C:\Program Files\7-Zip\7z.exe";
string sourceCompressDir = @"C:\Test";
string targetCompressName = @"C:\Test\abc.zip";
string CompressName = targetCompressName.Split('\\').Last();
string[] fileCompressList = Directory.GetFiles(sourceCompressDir, "*.*");
if (fileCompressList.Length == 0)
{
MessageBox.Show("No file in directory", "Important Message");
return;
}
string filetozip = null;
foreach (string filename in fileCompressList)
{
filetozip = filetozip + "\"" + filename + " ";
}
ProcessStartInfo pCompress = new ProcessStartInfo();
pCompress.FileName = PZipPath;
if (chkRequestPWD.Checked == true)
{
pCompress.Arguments = "a -tzip \"" + targetCompressName + "\" " + filetozip + " -mx=9" + " -p" + tbPassword.Text;
}
else
{
pCompress.Arguments = "a -tzip \"" + targetCompressName + "\" \"" + filetozip + "\" -mx=9";
}
pCompress.WindowStyle = ProcessWindowStyle.Hidden;
Process x = Process.Start(pCompress);
x.WaitForExit();
将属性设置为以下内容可以在3.91秒内完成相同的工作（即存档将具有相同的容器信息，即您可以使用7zip提取和测试存档，但没有文件名信息）
本机7zip 2秒钟。
CoderPropID[] propIDs = {
//CoderPropID.DictionarySize,
//CoderPropID.PosStateBits,
//CoderPropID.LitContextBits,
//CoderPropID.LitPosBits,
//CoderPropID.Algorithm,
//CoderPropID.NumFastBytes,
//CoderPropID.MatchFinder,
CoderPropID.EndMarker
};
object[] properties = {
//(Int32)(dictionary),
//(Int32)(posStateBits),
//(Int32)(litContextBits),
//(Int32)(litPosBits),
//(Int32)(algorithm),
//(Int32)(numFastBytes),
//mf,
eos
};
安装名为SevenZipSharp.Interop的NuGet包。
然后：
SevenZipBase.SetLibraryPath(@".\x86\7z.dll");
var compressor = new SevenZip.SevenZipCompressor();
var filesToCompress = Directory.GetFiles(@"D:\data\");
compressor.CompressFiles(@"C:\archive\abc.7z", filesToCompress);
SharpCompress 在我看来是最聪明的压缩库之一。它支持LZMA（7-zip），易于使用且正在积极开发中。
由于它已经支持LZMA流式传输，但遗憾的是目前仅支持7-zip存档读取。但是存档写入在他们的待办事项列表中（请参见自述文件）。对于未来的读者：请在此处查看当前状态：https://github.com/adamhathcock/sharpcompress/blob/master/FORMATS.md
