问题描述
我正在使用 7zip sdk (http://www.7-zip.org/sdk.html) 来压缩文件.
I am using 7zip sdk (http://www.7-zip.org/sdk.html) to compress a file.
使用此包装器可以正常工作:
it works fine using this wrapper:
public void EncodeSingleFile(FileStream inStream, FileStream outStream) {
bool eos = false;
Int32 dictionary = 1 << 21;
Int32 posStateBits = 2;
Int32 litContextBits = 3; // for normal files
// UInt32 litContextBits = 0; // for 32-bit data
Int32 litPosBits = 0;
// UInt32 litPosBits = 2; // for 32-bit data
Int32 algorithm = 2;
Int32 numFastBytes = 128;
string mf = "bt4";
propIDs = new CoderPropID[]
{
CoderPropID.DictionarySize,
CoderPropID.PosStateBits,
CoderPropID.LitContextBits,
CoderPropID.LitPosBits,
CoderPropID.Algorithm,
CoderPropID.NumFastBytes,
CoderPropID.MatchFinder,
CoderPropID.EndMarker
};
properties = new object[]
{
dictionary,
posStateBits,
litContextBits,
litPosBits,
algorithm,
numFastBytes,
mf,
eos
};
Encoder encoder = new Encoder();
encoder.SetCoderProperties(propIDs, properties);
encoder.WriteCoderProperties(outStream);
Int64 fileSize = inStream.Length;
for (int i = 0; i < 8; i++)
{
outStream.WriteByte((Byte) (fileSize >> (8*i)));
}
encoder.Code(inStream, outStream, -1, -1, null);
}
但是,我遇到了一个问题:
However, I have got a problem:
我只能使用从 7-zip.org 安装的 7zip shell 解压它,不能用 unrar 解压.如果我设置了一些参数并且它也适用于 unrar 是否可行?
I can only decompress it using 7zip shell installed from 7-zip.org, can not decompress with unrar. is that possible if I set some parameters and it will work with unrar as well?
如果我用 7zip 打开文件并检查属性,我得到:
If I open the file in 7zip and check the properties, I got:
- 名称:abc.pdb
- 尺寸:1 809 920
- 包装尺寸:249 305
- 方法:LZMA:21
- 类型:lzma
推荐答案
CodeProject 上有一个示例,有人使用 SDK 创建了 7z 的 C# 接口.他还提到现在可以对 DLL 使用 COM,但我不知道它是如何工作的.
There is an example on CodeProject of someone creating a C# interface for 7z using the SDK. He also mentions it is now possible to use COM against the DLL's, but I don't know how that works.
查看 7-Zip 存档 DLL 的 C# (.NET) 接口代码项目.
这篇关于使用7zip sdk压缩文件,但存档文件不是原始文件,无法使用unrar解压的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
