GZip Decompression Gives Blank File

Question

Given the code below, why is the decompression not working? "NewFile2.txt" should have the original, decompressed text, but the file is just blank.

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();
}

Answer 1

outFile.Flush(); // after your loop
