Answer 2

 public static string CompressString(string unCompressedString)
        {
            byte[] bytData = System.Text.Encoding.UTF8.GetBytes(unCompressedString);
            MemoryStream ms = new MemoryStream();
Stream s = null;
try
{
s = new GZipStream(ms, CompressionMode.Compress);
int totalRead = 0;
int bufLen = 4096;
int thisRead = 0;
while (true)
{
if (totalRead < bytData.Length)
{
thisRead = bytData.Length - totalRead;
if (thisRead > bufLen)
thisRead = bufLen;
s.Write(bytData, totalRead, thisRead);
totalRead = totalRead + thisRead;
}
else
break;
}
}
catch (Exception e)
{
LogUtil.LogError("Compress String Error:" + e.Message);
}
finally
{
if (s != null)
{
s.Close();
s.Dispose();
                    s = null;
}
}
            byte[] compressedData = (byte[])ms.ToArray();
ms.Close();
ms.Dispose();
            return System.Convert.ToBase64String(compressedData, 0, compressedData.Length);        }
