I'm getting an error when starting a FileSystemWatcher for a path that contains an inaccessible folder.
The folder is not accessible even by file system, if I try to access it I get a popup message asking me to grant permanent access to my user, this is completely fine but I'd like to handle it in my application to correctly start the watcher.
_watcher = new FileSystemWatcher(_path, _filter)
{
IncludeSubdirectories = true,
NotifyFilter = NotifyFilters.LastAccess
| NotifyFilters.LastWrite
| NotifyFilters.FileName
| NotifyFilters.DirectoryName
};
_watcher.Changed += new FileSystemEventHandler(OnChanged);
_watcher.Created += new FileSystemEventHandler(OnCreated);
_watcher.Deleted += new FileSystemEventHandler(OnDeleted);
_watcher.Renamed += new RenamedEventHandler(OnRenamed);
_watcher.EnableRaisingEvents = true;
The exception I'm getting is this
UnauthorizedAccessException: Access to the path 'D:\some_folder' is denied.

The paths exists, it's inside an usb key for which I have read/write permissions, it's only a specific folder which raises the issue.
Is there a way to safely catch this exception and start the watcher?
You could first check the permissions:
public static bool HasWritePermissionOnDir(string path)
{
var writeAllow = false;
var writeDeny = false;
var accessControlList = Directory.GetAccessControl(path);
if (accessControlList == null)
return false;
var accessRules = accessControlList.GetAccessRules(true, true,
typeof(System.Security.Principal.SecurityIdentifier));
if (accessRules ==null)
return false;
foreach (FileSystemAccessRule rule in accessRules)
{
if ((FileSystemRights.Write & rule.FileSystemRights) != FileSystemRights.Write)
continue;
if (rule.AccessControlType == AccessControlType.Allow)
writeAllow = true;
else if (rule.AccessControlType == AccessControlType.Deny)
writeDeny = true;
}
return writeAllow && !writeDeny;
}

I'm working with MRTK in Unity and I'm trying to access the namespace Microsoft.MixedReality in a script, but I get the error that MixedRealty doesn't exist at Microsoft namespace. However, at the MixedReality script all the namespaces are found, which troubles me for not knowing how to access the namespace.
At the same time, I'm getting this error at the console log:
System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Users\User\Documents\cummins-loto\Library\PackageCache\com.microsoft.mixedreality.toolkit.foundation#a77cb7137a89-1660746982947\SDK\Experimental\InteractiveElement\Examples\Scripts\CustomStateExample\KeyboardState'.

I don't know what do I have to do to fix that error, I've tried reimporting all assets, regenerating project files, moving the script on which I need to access the namespace to another and erasing the Library folder, but hasn't worked. I hope someone knows a solution!
Thanks in advance.

I am trying to read a zip file remotly from a url this bit works fine if its from disk but I want to read it remotly without unzipping the file first is that possible or would it make the file inacessable to others?.
public void GetMSFSAddonDetails(string zipFileUrl) {
using (ZipArchive archive = ZipFile.OpenRead(zipFileUrl))
{
var sample = archive.GetEntry("manifest.json");
if (sample != null)
{
using (var zipEntryStream = sample.Open())
{
// serializer = new XmlSerializer(typeof(SampleClass));
/// SampleClass deserialized =
// (SampleClass)serializer.Deserialize(zipEntryStream);
}
}

As far as I know the method ZipFile.OpenRead(String) does not handle URLs! It expects an archiveFileName and searches on the disk.
You would probably have to download the zip file and open it afterwards.
I am running Windows 10, Visual Studio 2015, and Xamarin. I am rather new to Xamarin (just to set the ground level). I am currently having an issue after I updated recently. My application was working before the update. All my files were read-only, and I had no issues prior the update. Along with that, I have rebuilt the project and I the "clean and rebuild" for the project as well. I have tried it with multiple apps I have, and the other applications do not have this issue. The issue I am getting the following error below.

06-26 13:51:55.153 W/art ( 6985): JNI RegisterNativeMethods: attempt to register 0 native methods for android.runtime.JavaProxyThrowable
An unhandled exception occured.
I've read few articles such as (I posted the Google search for the 3rd item because I read almost everything in the top results). I've tried running the program as an administrator and the directory has open access to anyone.
Why is access to the path denied?
System.UnauthorizedAccessException: Access to the path "..." is denied

For anyone curious on the code of how I am accessing my file, it is below.
private List<string> readUsers()
{
adminUsers = new List<string>();
try
{
StreamReader readerForFile;
//create checks for making sure the card is mounted, the directory is found, and the file is found.
var filePath = Path.Combine(Android.OS.Environment.ExternalStorageDirectory.Path, "defaultDirectory/users.ini");
File.SetAttributes(filePath, FileAttributes.Normal);
if (File.Exists(filePath))
{
//Reads enttire document
//var fillContent = File.ReadAllText(filePath);
readerForFile = File.OpenText(filePath);
if (readerForFile == null) { return null; }
else
{
string line = "";
int counter = 0;
while ((line = readerForFile.ReadLine()) != null)
{
adminUsers.Add(line);
counter++;
}
}
}
}
catch (IOException e)
{
//You'll need to add proper error handling here
alert.SetMessage("File was not found. " + e).SetNeutralButton("Okay", delegate { QuestionActivity.exit(); }).Create().Show();
}
return adminUsers;
}
You should enable READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions in Android.
You can follow this blog to enable the permission in runtime

I need to parse XML string with Linq, and I came up with the following code.
using System;
using System.Linq;
using System.Xml.Linq;
class LinqXml
{
public void Parse(string input)
{
XDocument xdoc = XDocument.Load(input);
var lang = from d in xdoc.Elements("PipeUnit").Elements("Step").Elements("Pipelist").Elements("NamedPipe").Elements("NameOfPipe") select d;
Console.WriteLine(lang.First().Value);
foreach (var item in lang)
{
Console.WriteLine(item.Value);
}
}
static void Main()
{
string tempString = #"
<PipeUnit>
<Step>
<Pipelist>
<NamedPipe>
<NameOfPipe>Name</NameOfPipe>
<PipeData>Data</PipeData>
</NamedPipe>
</Pipelist>
</Step>
</PipeUnit>
";
var linqXml = new LinqXml();
linqXml.Parse(tempString);
}
}
When compile this code with Mono - dmcs linqxml.cs /r:System.Xml.Linq.dll, and tried to run, I got the following errors.
Unhandled Exception: System.IO.DirectoryNotFoundException: Could not find a part of the path "/Users/smcho/Desktop/csharp/

<Step>
<Pipelist>
<NamedPipe>

<PipeData>Data</PipeData>
</NamedPipe>
</Pipelist>
</Step>
<PipeUnit>".

What might be wrong?
Replace this:
XDocument xdoc = XDocument.Load(input);
with:
XDocument xdoc = XDocument.Parse(input);
you are passing XML, not a file name.
in your Parse method, you want
XDocument.Parse(input)
Replace
XDocument xdoc = XDocument.Load(input);
with
XDocument xdoc = XDocument.Parse(input);
