protobuf从字节数组转换为对象

• 主要的核心就是mergeFrom

		public static object FromBytes(Type type, byte[] bytes, int index, int count)
		{
			object message = Activator.CreateInstance(type);
			((Google.Protobuf.IMessage)message).MergeFrom(bytes, index, count);
			ISupportInitialize iSupportInitialize = message as ISupportInitialize;
			if (iSupportInitialize == null)
			{
				return message;
			}
			iSupportInitialize.EndInit();
			return message;
		}
