            else if (read == 0xFE)

                // Special encoding for Int32.MaxValue
                val = uint.MaxValue - 1;
            }
            else if (read == 0xFF)
            {
                // Yes we treat UInt32.MaxValue (and Int32.MinValue, see ReadCompressedInt32) specially
                val = uint.MaxValue;
            }
            // Add code
            else if (read == 0xE8)
            { 
                val = 0;
            }
            else
            {
                throw new Exception("Invalid compressed integer format");
            }

            return val;
        }

修改这个方法添加0xE8的判断即可
