C#实现解压GZip文件的方法
本文实例讲述了C#实现解压GZip文件的方法。分享给大家供大家参考。具体实现方法如下:
publicvoidungzip(stringpath,stringdecomPath,booloverwrite) { //foroverwritingpurposes if(File.Exists(decomPath)) { if(overwrite) { File.Delete(decomPath); } else { thrownewIOException("Thedecompressedpathyouspecifiedalreadyexistsandcannotbeoverwritten."); } } //createourfilestreams GZipStreamstream=newGZipStream(newFileStream(path,FileMode.Open,FileAccess.ReadWrite),CompressionMode.Decompress); FileStreamdecompressedFile=newFileStream(decomPath,FileMode.OpenOrCreate,FileAccess.Write); //datarepresentsabytefromthecompressedfile //it'ssetthrougheachiterationofthewhileloop intdata; while((data=stream.ReadByte())!=-1)//iteratesoverthedataofthecompressedfileandwritesthedecompresseddata { decompressedFile.WriteByte((byte)data); } //closeourfilestreams decompressedFile.Close(); stream.Close(); }
希望本文所述对大家的C#程序设计有所帮助。
