GZip解压给出空白文件
|
给定以下代码，为什么解压缩不起作用？ \“ NewFile2.txt \”应该具有原始的，已解压缩的文本，但是文件只是空白。
ioTests.CompressFile(@\"c:\\newfile.txt\", @\"c:\\newfile.txt.gz\");
ioTests.DecompressFile(@\"c:\\newfile.txt.gz\", @\"c:\\newfile2.txt\");
public void CompressFile(string inFileName, string outFileName)
{
FileStream inFile = new FileStream(inFileName, FileMode.Open);
FileStream outFile = new FileStream(outFileName, FileMode.Create);
GZipStream compStream = new GZipStream(outFile, CompressionMode.Compress);
int theByte = inFile.ReadByte();
while (theByte != -1)
{
compStream.WriteByte((byte)theByte);
theByte = inFile.ReadByte();
}
compStream.Close();
}
public void DecompressFile(string inFileName, string outFileName)
{
FileStream inFile = new FileStream(inFileName, FileMode.Open);
FileStream outFile = new FileStream(outFileName, FileMode.CreateNew);
GZipStream compStream = new GZipStream(inFile, CompressionMode.Decompress);
int theByte = compStream.ReadByte();
while (theByte != -1)
{
outFile.WriteByte((byte)theByte);
theByte = compStream.ReadByte();
}
compStream.Close();
}

因为这会刷新流并调用Dispose方法，从而释放分配的资源。壤欠攻混
接口，因此您应在/类中使用类，或使用语句自动执行此操作：using (FileStream inFile = new FileStream(inFileName, FileMode.Open)) using (FileStream outFile = new FileStream(outFileName, FileMode.Create)) using (GZipStream compStream = new GZipStream(outFile, CompressionMode.Compress)) { int theByte = inFile.ReadByte(); // ... Rest of your code }try { FileStream inFile = new FileStream(inFileName, FileMode.Open); FileStream outFile = new FileStream(outFileName, FileMode.Create); GZipStream compStream = new GZipStream(outFile, CompressionMode.Compress); int theByte = inFile.ReadByte(); // ... Rest of your code } finally { if (inFile != null) inFile.Dispose(); if (outFile != null) outFile.Dispose(); if (compStream != null) compStream.Dispose(); }
