我基于一个CodeProject文章编写了一个包装器类(C#),使用压缩。它可以很好地压缩,但无法解压缩。我查看了许多其他有相同问题的示例,感觉我在遵循所说的方法,但在解压缩时仍然得不到任何东西。这是压缩和解压缩方法:
public static byte[] Compress(byte[] bSource)
{
using (MemoryStream ms = new MemoryStream())
{
using (GZipStream gzip = new GZipStream(ms, CompressionMode.Compress, true))
{
gzip.Write(bSource, 0, bSource.Length);
gzip.Close();
}
return ms.ToArray();
}
}
public static byte[] Decompress(byte[] bSource)
{
try
{
using (MemoryStream ms = new MemoryStream())
{
using (GZipStream gzip = new GZipStream(ms, CompressionMode.Decompress, true))
{
gzip.Read(bSource, 0, bSource.Length);
gzip.Close();
}
return ms.ToArray();
}
}
catch (Exception ex)
{
throw new Exception("Error decompressing byte array", ex);
}
}
以下是我使用它的示例:
string sCompressed = Convert.ToBase64String(CompressionHelper.Compress("Some Text"));
// Other Processes
byte[] bReturned = CompressionHelper.Decompress(Convert.FromBase64String(sCompressed));
// bReturned has no elements after this line is executed
