Why is XmlSerializer's Deserialize() spitting out a child object which is a XmlNode[]?

五迷三道 提交于 2020-01-14 04:32:06
问题 I'm using XmlSerializer to serialize and then deserialize a simple object. When I deserialize the object to my surprise I find a child object was not properly deserialized but instead turned into XmlNode[] . Here is very nearly the structure I've got: // This line I put in here as a way of sneaking into the XML the // root node's C# namespace, since it's not the same as the // deserializing code and the deserializing code seemed unable to // deserialize properly without knowing the Type (see

PHP serialize/unserialize like method in Objective-C

試著忘記壹切 提交于 2020-01-14 04:13:08
问题 I have serialized a string in PHP using serialize method $serializedResult = serialize($value); How to unserialize this serialized string in Objective-C 回答1: I don't think there is a serialized PHP object parser for Objective C. However you could use JSON instead. On the PHP side use json_encode , and on the Objective C side see: http://blog.zachwaugh.com/post/309924609/how-to-use-json-in-cocoaobjective-c Or as Tommy pointed out the now native implementation: http://developer.apple.com

Having lots of trouble with serialization in MVVM

浪尽此生 提交于 2020-01-14 04:12:09
问题 I am working on a text-based game in WPF and I'm exploring MVVM. Currently I have 2 models in my project, Adventurer and GameDate (I am not concerned at this point with what should or should not be a model. I'll tackle that later). I have a viewmodel MainViewModel and a view MainView . MainView has buttons bound to save/load commands... And that's sort of where I'm stuck. I would very much like to implement a form of binary serialization; I have a class ObjectSerializer that functions and the

Why doesn't Django serialize FileField to the file url when using AWS S3

雨燕双飞 提交于 2020-01-14 03:52:30
问题 Scenario: I'm using Amazon S3 as default storage using S3 Boto and all files would be going to 'media' folder in my bucket. Question: When I am serializing the model containing my FileField to json using serializers.serialize , all I get in the json is 'media/abc.png' or something of that sort. Is there a way to automatically get the file url in json instead of the relative path or should I manually append the url into the json response every time? 回答1: Django operates with File objects,

How to store value objects in a relational database?

我怕爱的太早我们不能终老 提交于 2020-01-14 03:18:08
问题 I am working with a large project that has many objects that represent simple (non-related) values. Sometimes these values are a single string, sometimes they are two strings, sometimes a string and an int... Currently we have a 'values' table in our relational database that contains the columns: Id , Category , String1 , String2 ..., Int1 , Int2 ..., Double1 etc. It's convenient, but a mess. The values all have the following properties: Every object with the same Category has the same

MVVMLight and Data Serialisation

前提是你 提交于 2020-01-14 03:04:08
问题 I'm getting started with MVVMLight for a Windows 8 Store app. I've got the basics working after viewing some videos. however I have run into an issue. Each of my base model classes inherit from ObservableObject in MVVMLight. This was working fine but I now want to load and save data to XML. So I marked them with DataContract attribute which I'd used previously in a non MVVM implementation. However this now creates an error when serialising as it says my inherited classes must also be marked

R - evaluate nested function call in a deserialized environment

守給你的承諾、 提交于 2020-01-14 02:53:10
问题 I am trying to run an already existing chunk of R code in a sandbox-ed fashion, by saving the global environment (containing functions and data) to a file, then loading it into a new environment (not the global environment) and evaluating a function call within that environment. However, I'm running into trouble with functions calling other functions in the environment. Here's an example: f1 <- function(x) x*2 f2 <- function(y) f1(y) + 1 save(list=ls(), file="env.RData") rm(list=ls()) jobenv

Generics and ReadObject

前提是你 提交于 2020-01-14 01:36:15
问题 I have a simple server that uses generics and object serialization. (T is the input format, U is the output format). A simplified version that only deals with input is shown below: public class Server <T, U> implements Runnable { @override public void run () { try (ObjectInputStream inReader = new ObjectInputStream (this.connection.getInputStream ())) { T lastObj; while (true) { lastObj = (T) inReader.readObject (); System.out.println (lastObj.getClass ().getName ()); if (null != lastObj) {
