Question

为什么我不能在这里使用此代码？我想在一个先前压缩的字节数组上调用它....无论如何，它只返回一个空字符串...

    public static string FromGZipToString( this byte[] source )
    {
        using( MemoryStream stream = new MemoryStream( ) )
        {
            stream.Write( source, 0, source.Length );

            using (var gzipstream = new GZipStream(stream, CompressionMode.Decompress))
            using (var reader = new StreamReader(gzipstream)) 
            {
               return reader.ReadToEnd( );
            }
        }
    }

这是压缩代码......

    public static byte[] ToGZip( this string source )
    {
        using( var stream = new MemoryStream( ) )
        using( var compressor = new GZipStream( stream, CompressionMode.Compress ) )
        {
            var bytes = System.Text.UTF8Encoding.UTF8.GetBytes( source );

            compressor.Write( bytes, 0, bytes.Length );

            return stream.ToArray( );
        }
    }

您的压缩程序有问题。在压缩机关闭（或处理）之前，它不应该从流读取，允许压缩器完成将所有字节写入蒸汽。
