C# (xamarin project) not able to find path to the file

I have this problem when I'm trying to read JSON file (or any file): It's not able to find that file. I try everything, even the absolute path (error almost same - DirectoryNotFound)
This is structure of mine code:
And this is code:
private void LoadJson()
{
using (var r = new StreamReader("quizQuestions.json"))
{
string json = r.ReadToEnd();
items = JsonConvert.DeserializeObject<List<Questions>>(json);
}
}
I I even try to use Directory.GetCurrentDirectory() but it's returning : / -> only this character. I don't know where is a mistake or if I forgot to set something. I try to find answers everywhere but I was not able to find anything with this.

Make sure the Build Action of the file is set as Content or as an Asset and give this a try.
private void LoadJson()
{
AssetManager assets = this.Assets;
using (var r = new StreamReader(assets.Open ("quizQuestions.json")))
{
string json = r.ReadToEnd();
items = JsonConvert.DeserializeObject<List<Questions>>(json);
}
}

You can configure the file as Embedded Resource and then access it like this:
public static Stream GetEmbeddedResourceStream(Assembly assembly, string resourceFileName)
{
var resourceNames = assembly.GetManifestResourceNames();
var resourcePaths = resourceNames
.Where(x => x.EndsWith(resourceFileName, StringComparison.CurrentCultureIgnoreCase)).ToArray();
if (resourcePaths.Any() && resourcePaths.Count() == 1)
{
return assembly.GetManifestResourceStream(resourcePaths.Single());
}
return null; // or throw Exception
}
private void LoadJson()
{
Assembly assembly = GetAssemblyContainingTheJson();
using (var r = GetEmbeddedResourceStream(assembly, "quizQuestions.json"))
{
string json = r.ReadToEnd();
items = JsonConvert.DeserializeObject<List<Questions>>(json);
}
}

How to pass xml file inside of code instead of a folder path?

I'am trying to not create a file, and pass xml document straight to a SkiaSharp method Load. I mean, is there the way to imitate a path? So here is the code:
public IActionResult svgToPng(string itemId, string mode = "
{
var svgSrc = new XmlDocument();
svgSrc.LoadXml(/*Some xml code*/);
string svgSaveAs = "save file path";
var quality = 100;
var svg = new SkiaSharp.Extended.Svg.SKSvg();
var pict = svg.Load(svgSrc); // HERE, it needs to be a path, not XmlDocument, but i want to pass straight
var dimen = new SkiaSharp.SKSizeI
(
(int) Math.Ceiling(pict.CullRect.Width),
(int) Math.Ceiling(pict.CullRect.Height)
);
var matrix = SKMatrix.MakeScale(1, 1);
var img = SKImage.FromPicture(pict, dimen, matrix);
// Convert to PNG
var skdata = img.Encode(SkiaSharp.SKEncodedImageFormat.Png, quality);
using(var stream = System.IO.File.OpenWrite(svgSaveAs))
{
skdata.SaveTo(stream);
}
ViewData["Content"] = "PNG file was created out of SVG.";
return View();
}
The Load method seems to be this:
public SKPicture Load(
using (var stream = File.OpenRead(filename))
{
return Load(stream);
}
}

look at the code of that library :
https://github.com/mono/SkiaSharp.Extended/blob/master/SkiaSharp.Extended.Svg/source/SkiaSharp.Extended.Svg.Shared/SKSvg.cs
Look at the Load method, it has multiple implementations :
public SKPicture Load(string filename)
{
using (var stream = File.OpenRead(filename))
{
return Load(stream);
}
}
public SKPicture Load(Stream stream)
{
using (var reader = XmlReader.Create(stream, xmlReaderSettings, CreateSvgXmlContext()))
{
return Load(reader);
}
}
public SKPicture Load(XmlReader reader)
{
return Load(XDocument.Load(reader));
}
You will need to pick one of them and use it. Now, nothing stops you from getting the code and adding one extra Load for an XML string for example, but since this is a library you do not control, I'd stick to what you are given.
You could use the XmlReader version, that's probably the closest one to what you want.

Windows Phone 7: Check If Resource Exists

I need to check whether an embedded resource exists. In WPF this i relatively easy, but in WP7 I get a MissingManifestResourceException
The WPF code which works is:
public static IEnumerable<object> GetResourcePaths(Assembly assembly) {
var culture = System.Threading.Thread.CurrentThread.CurrentCulture;
//var resourceName = assembly.GetName().Name + ".g";
var assemblyName = assembly.FullName.Split(',')[0];
var resourceName = assemblyName + ".g";
var resourceManager = new ResourceManager(assemblyName, assembly);
try {
var resourceSet = resourceManager.GetResourceSet(culture, true, true);
foreach (System.Collections.DictionaryEntry resource in resourceSet) {
yield return resource.Key;
}
} finally {
resourceManager.ReleaseAllResources();
}
}
I tried replacing it with the code below, which resulted in the exception (on line 9). Is there a way to do this in Silverlight / WP7?
public static IEnumerable<object> GetResourcePaths(Assembly assembly) {
var culture = System.Threading.Thread.CurrentThread.CurrentCulture;
//var resourceName = assembly.GetName().Name + ".g";
var assemblyName = assembly.FullName.Split(',')[0];
var resourceName = assemblyName + ".g";
var resourceManager = new ResourceManager(assemblyName, assembly);
try {
var resourceSet = resourceManager.GetResourceSet(culture, true, true);
foreach (System.Collections.DictionaryEntry resource in resourceSet) {
yield return resource.Key;
}
} finally {
resourceManager.ReleaseAllResources();
}
}

The answer to this previous question: WP7: collection of images seems to indicate that you might need to get a stream before calling GetResourceSet:
var NOT_USED = rm.GetStream("app.xaml"); // without getting a stream, next statement doesn't work - bug?
Sounds a bit hacky, but if it works ;)

C# - Cannot getting a string from ResourceManager (from satellite assembly)

I'm developing a localisable application. In my "local" resource file, I've the language used by default (english) and if possible, I load the user's preference and culture and load strings translated in is language.
So what I've done :
private static CultureInfo _culture = CultureInfo.CurrentUICulture;
private static ResourceManager _manager;
private static void ToNeutralCulture()
{
while (!_culture.IsNeutralCulture)
{
_culture = _culture.Parent;
}
}
private static void LoadCulture()
{
ResourceManager manager = Properties.Resources.ResourceManager;
try
{
ToNeutralCulture();
string assembly = Assembly.GetCallingAssembly().GetName().CodeBase;
string assemblyDir = Path.GetDirectoryName(assembly);
string assemblyName = Path.GetFileNameWithoutExtension(assembly);
string resourceFileName = string.Format(CultureInfo.InvariantCulture,
#"{0}\{1}_{2}.dll",
assemblyDir,
assemblyName,
_culture.Name.ToUpper());
FileInfo resourceFile = new FileInfo(resourceFileName);
if (resourceFile.Exists)
{
Assembly resourceAssembly = Assembly.LoadFrom(resourceFile.FullName);
string[] manifests = resourceAssembly.GetManifestResourceNames();
if (manifests.Length == 1)
{
manager = new ResourceManager(manifests[0], resourceAssembly);
}
using (ResourceReader reader = new ResourceReader(resourceAssembly.GetManifestResourceStream(manifests[0])))
{
IDictionaryEnumerator dict = reader.GetEnumerator();
while (dict.MoveNext())
{
string key = dict.Key as string;
object val = dict.Value;
//string mVal = manager.GetString(key);
}
}
}
}
catch (Exception ex)
{
Trace.WriteLine(ex.Message);
Trace.WriteLine(string.Format(CultureInfo.InvariantCulture,
"Fail to loading culture {0}",
(_culture == null) ? "--" : _culture.EnglishName));
}
_manager = manager;
}
Assembly is correctly loaded and the enumerator will display me all resources present in the resource file, well, works fine except :
string mVal = manager.GetString(key);
When I uncommented this line, I've an System.Resources.MissingManifestResourceException, can someone tell me why?
Thanks !
[EDIT]
Project "MyApp"
namespace MyApp
{
Assembly resourceAssembly = Assembly.LoadFrom(resourceFileName);
string[] manifests = resourceAssembly.GetManifestResourceNames();
if (manifests.Length == 1)
{
manager = new ResourceManager(manifests[0], resourceAssembly);
}
// Throws the exception
manager.GetString("PleaseCallIT", null);
// Works
using (ResourceReader reader = new ResourceReader(resourceAssembly.GetManifestResourceStream(manifests[0])))
{
IDictionaryEnumerator dict = reader.GetEnumerator();
while (dict.MoveNext())
{
string key = dict.key as string; // PleaseCallIT
object val = dict.value; // Please call IT.
}
}
}
Project "MyApp_FR" (Resources.Designer.cs auto-generated file)
namespace MyApp.Properties {
// ...
internal static string PleaseCallIT {
get {
return ResourceManager.GetString("PleaseCallIT", resourceCulture);
}
}
}
I don't understand...

I found why, hope this will help someone that is in the same case.
So, I looked in MyApp_FR.dll the code generated to use the Resource file, it is :
new global::System.Resources.ResourceManager("MyApp_FR.Properties.Resources", typeof(Resources).Assembly);
but when retrieving the manifest file names, I got :
"MyApp_FR.Properties.Resources.resources"
Seems to be there is a .resource to much in this room... By removing it, I can use my ResourceManager normally, all works fine...
Final code :
Assembly resourceAssembly = Assembly.LoadFrom(resourceFileName);
string[] manifests = resourceAssembly.GetManifestResourceNames();
if (manifests.Length == 1)
{
string manifest = manifests[0].Replace(".resources", string.Empty);
manager = new ResourceManager(manifest, resourceAssembly);
}
// Works !
manager.GetString("PleaseCallIT", null);

From Microsoft Support:
This problem occurs if you use a localized resource that exists in a satellite assembly that you created by using a .resources file that has an inappropriate file name. This problem typically occurs if you manually create a satellite assembly:
Try this KB:
http://support.microsoft.com/kb/839861

An alternate approach, put in the following as test code:
string[] resources =
System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames();
In debugging, check the contents of resources to see if it matches what you are loading with ResourceManager.
Especially note, if you get something like 'MyAssembly..Resources.resources', then you will need to explicitly add 'Resources' to the ResourceManager constructor:
private static readonly ResourceManager stringTable =
new ResourceManager("MyAssembly.Resources", Assembly.GetExecutingAssembly());

C#: Reading the content of a file, which is embedded in a resource file

How can I read a text file, which is embedded in a resx file with the help of the ResourceManager class?
Whats wrong with the following snippet?
ResourceManager resman = new ResourceManager("Mynamespace.RESXFileName", Assembly.GetExecutingAssembly());
Stream stream = resman2.GetStream("ResourceName");
stream is alway = null!

using (var resourceStream = Assembly.GetExecutingAssembly()
.GetManifestResourceStream(resourceName))
{
if (resourceStream != null)
{
using (var textStreamReader = new StreamReader(resourceStream))
{
text = textStreamReader.ReadToEnd();
}
}
else
{
throw (new MissingManifestResourceException(resourceName));
}
}
The resource name is determined by namespace and filename. Say file MyTxt.txt exists in the root of the project, which has default namespace MyNs then the resource name will be: MyNs.MyTxt.txt
EDIT
I should learn to read the question. I haven't tested but this should give you what you want:
static object GetResxObject(string resxPathName, string resourceKey)
{
using (var resxReader = new ResXResourceReader(resxPathName))
{
return resxReader
.Cast<DictionaryEntry>()
.Single(d => string.Equals(d.Key,
resourceKey))
.Value;
}
}
...
var myString=(string)GetResxObject(#"path\to\resx.resx","myStringKey");

<ResourceNamespace>.ResourceManager.GetString(<textresourcename>);
