问题描述
我想从一个 zip 文件中读取一个二进制文件而不解压它.
I would like to read a binary file from a zip file without unzipping it .
zip 文件结构:
zipFolderName/subFolder/BinFile
在 BinFile 中,我有:
In the BinFile, I have:
Id1, id2, value1 // id1, id2 are string, value1 is int
在 C# 中:
ZipEntry binFileName = …; // it has been got from zipFile entries
MemoryStream ms = new MemoryStream();
binFileName.Extract(ms);
using (BinaryReader reader = new BinaryReader(ms))
{
string id1 = reader.ReadString(); // error popped here
string id2 = reader.ReadString();
int value1 = reader.ReadInt32();
}
我遇到错误:无法读取流的末尾.似乎 BinaryReader 无法读取 MemoryStream ?
I got error: Unable to read beyond the end of the stream. It seems that BinaryReader cannnot read MemoryStream ?
推荐答案
在 binFileName.Extract(ms);
之后尝试以下操作:
After binFileName.Extract(ms);
try the following:
ms.Seek(0, SeekOrigin.Begin);
