After going through pretty much every forum and tutorial available I’m still unable to solve this.
I simply want to load and save xml data via runtime. It works in the editor, but not after build.
The paths are correct, I checked that (even after build).
Beside Application.streamingAssetsPath I’ve also tried dataPath and persistentDataPath. I’ve tried to put everything in the StreamingAssets folder that Unity copies and also in the C:/Users/User/DefaultCompany… path. It all works out perfectly fine before I build it…
Any suggestions?
//Save the streamingDataObject to xml
public void Save()
{
//Create new xml file
XmlSerializer serializer = new XmlSerializer(typeof(ObjectDataBase)); //Create serializer
FileStream stream = new FileStream(Application.streamingAssetsPath + "/XML/ObjectData", FileMode.Create); //Create file at this path
serializer.Serialize(stream, oList);//Write the data in the xml file
stream.Close();//Close the stream
}
//Load xml file
public void Load()
{
XmlSerializer serializer = new XmlSerializer(typeof(ObjectDataBase)); //Create serializer
FileStream stream = new FileStream(Application.streamingAssetsPath + "/XML/ObjectData", FileMode.Open); //Load file at this path
oList = serializer.Deserialize(stream) as ObjectDataBase;
stream.Close();//Close the stream
}
This worked for me in both editor and after building:
[Serializable]
public struct Foo
{
public int x;
public int y;
public override string ToString() { return "x: " + x + ", y: " + y; }
}
string fileName = Application.streamingAssetsPath + "/XML/ObjectData.xml";
public void Save()
{
var foo = new Foo()
{
x = 5,
y = 10
};
XmlSerializer serializer = new XmlSerializer(typeof(Foo));
using (FileStream stream = new FileStream(fileName, FileMode.Create))
{
serializer.Serialize(stream, foo);
}
}
public void Load()
{
XmlSerializer serializer = new XmlSerializer(typeof(Foo));
using (FileStream stream = new FileStream(fileName, FileMode.Open))
{
var foo = serializer.Deserialize(stream);
Debug.Log(foo);
}
}
If you’re still having issues after building, then it’s likely you’re running into a permissions issue when trying to create an XML file in the build path. In my application’s installer, I set user-modify permissions on the data folder in order to allow me to create files there from within the application (it was actually for the output_log.txt log file that Unity generates, but you’ll likely need this for the XML file to be created).
I don’t think it’s an permission issue, since im the administrator. Also the StreamingAssets folder is build by Unity itself and it worked in editor mode. Maybe the DevelopmentBuild-log helps? I can read that something is wrong but not realy what it is. It told me not to use Application.streamingAssetsPath during serialisation, so I moved it to Start(). The warning is gone now, still doesn’t work, though.
Your code didn’t work either, throwing me an “InvalidOperationException: was not expected” exception. I’ll try moving around some lines.
Edit: I fixed the exception by adding
[Serializable, XmlRoot("StreamingData")]
public struct Foo
{...}
Edit #2:
Still, xml isn’t loaded (I guess, stupid as I am I simply output the data directly instead of loading my xml).
Weirdly enough, that doesn’t seem to matter if you’re building for Windows standalone. I’m not sure what platform you’re targeting, but in my case, I still had to set the user-modify permission even though I’m the administrator as well. However, this seems to only be true if I install to C:\Program FIles. If the build is anywhere else, then it works fine.
Your case may be different if you’re targeting a different platform though.
Are you getting any errors at all in the console output? Or does it just silently fail when trying to create the xml data?
No errors. It just fails. With your example “foo” contains the xml data, but I have no idea how to get the x and y values now. Also I need a list of objects, which contain a lot of data.
The struct is just a test case for trying to make sure serialization/deserialization works. It’s best to stick with something simple for now until you can be sure the file creation/serialization part works, then you can switch to a list afterwards.
Maybe you should first focus on trying to create the XML file in that path, and figure out why you’re not able to. Try using File.Create() (or File.CreateText()) in that path, and see if you get any errors or exceptions thrown. Hopefully that’ll give you more info to work with.
Im getting this error now, using development build to get a log file. And yes, yes I’m building for windows.
IOException: Sharing violation on path This should happen, if you try to read/write at the same time. It can usually be fixed by closing the stream, which I already do. So this is strange. Also this only appears if I hit the “Save” button in my application, to call Save(). Load() is called at Start().

I figured it out (after 12h straight).
Seems like I need to overwrite existing xml files in my build by saving them at runtime. Then I can restart it and it will load… the copied xml files, I saved while in editor mode won’t be loaded (even though they are copied into StreamingAssets and you can open and change them in the editor). Also you can’t just move xml files into your StreamingAssets folder. They have to be generatet during runtime. Ofcourse I’ve tried that before, but without setting the root element. [Serializable, XmlRoot(“StreamingData”)]
At least that seems to work.
Thanks for your effort.

I happen to have made a thread asking in a lot of detail about this subject and a user called HiddenMonk wrote some very detailed information on serialising gameobjects, it should help you a huge amount in the future if you run into problems dealing with XML in particular.
It is not a subject that programmers have done a lot of documentation about unfortunately as you can see in the thread I initially had to pick a fight with people in order to get a straight answer. Part of it seems to be just lack of interest in generally teaching or talking about the subject but another is you have to be very specific about what you want since you have multiple methods for various game genres and what type of data you’re saving.
