本文介绍了gzipstream.copyto替代简便的方法,在.NET 3.5中的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
喜在这code。在.NET 4中,我用CopyTo从gzipstream方法
hi in this code in .net 4 i used copyto method of gzipstream
System.IO.MemoryStream ms = new System.IO.MemoryStream(byteArray);
GZipStream DecompressOut = new GZipStream(ms, System.IO.Compression.CompressionMode.Decompress);
MemoryStream outmem = new MemoryStream();
DecompressOut.copyto(outmem);
FileStream outFile = new FileStream(fileName, FileMode.OpenOrCreate, FileAccess.Write);
StreamWriter m_streamWriter = new StreamWriter(outFile);
我怎么能直接写给写GZipStream到的MemoryStream或者的FileStream?
how can i diretly write GZipStream into MemoryStream or FileStream?
推荐答案
流之间复制是pretty的基础:
Copying between streams is pretty basic:
public static long CopyTo(this Stream source, Stream destination) {
byte[] buffer = new byte[2048];
int bytesRead;
long totalBytes = 0;
while((bytesRead = source.Read(buffer, 0, buffer.Length)) > 0) {
destination.Write(buffer, 0, bytesRead);
totalBytes += bytesRead;
}
return totalBytes;
}
因此,只要插上在,你应该进行排序:
So just plug that in, and you should be sorted:
using(var ms = new MemoryStream(byteArray))
using(var gzip = new GZipStream(ms, CompressionMode.Decompress))
using (var file = new FileStream(fileName, FileMode.OpenOrCreate,
FileAccess.Write)) {
gzip.CopyTo(file);
}
