压缩测试，适用于重复比较多的字符串，对比Zip和GZip，压缩率最高

string sourceStr = "key=中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国中国";

 byte[] pBytes = System.Text.Encoding.UTF8.GetBytes(sourceStr);
pBytes = Compress(pBytes);
string result = Convert.ToBase64String(pBytes);
MessageBox.Show(result.Length)
