How to get All attributes from an Active Directory user in C#

I have been searching for quite some time for a solution using C# code that can query an Active Directory user for all the attributes it has registered to it, whether or not they have a NULL Value. These attributes are visible through the Attribute editor tab in the properties of the user in ADSI Edit on the domain server.
AD user attributes in ADSI edit
I need to dynamically retrieve these attributes, which means I probably can't reliably get these attribute names through the ADSI documentation on MSDN and because not all of these attributes might be user object specific:
https://msdn.microsoft.com/en-us/library/ms675090(v=vs.85).aspx
Here is what I have tried so far, but only got a fraction of the attributes of the user object:
PS command Get-ADUser -Identity administrator -Properties: This retrieved a good part of the attributes, but not nearly all of them and I do not know what .NET Classes and methods are invoked during this command, since TypeName = Microsoft.ActiveDirectory.Management.ADUser, which does not exist in the .NET framework. How can I see the specific methods that are using from .NET in PS?
C# calling this method:
public bool GetUserAttributes(out List<string> userAttributes, string userName)
{
userAttributes = new List<string>();
var valueReturn = false;
try
{
const string pathNameDomain = "LDAP://test.local";
var directoryEntry = new DirectoryEntry(pathNameDomain);
var directorySearcher = new DirectorySearcher(directoryEntry)
{
Filter = "(&(objectClass=user)(sAMAccountName=" + userName + "))"
};
var searchResults = directorySearcher.FindAll();
valueReturn = searchResults.Count > 0;
StreamWriter writer = new StreamWriter("C:\\LDAPGETUSERADEXAMPLE.txt");
foreach (SearchResult searchResult in searchResults)
{
foreach (var valueCollection in searchResult.Properties.PropertyNames)
{
userAttributes.Add(valueCollection.ToString() + " = " + searchResult.Properties[valueCollection.ToString()][0].ToString());
try
{
writer.WriteLine("Bruger attribut:" + valueCollection);
}
catch (Exception)
{
throw;
}
}
}
C# calling this method:
public List<string> GetADUserAttributes()
{
string objectDn = "CN=testuser,OU=TEST,DC=test,DC=local";
DirectoryEntry objRootDSE = new DirectoryEntry("LDAP://" + objectDn);
List<string> attributes = new List<string>();
foreach (string attribute in objRootDSE.Properties.PropertyNames)
{
attributes.Add(attribute);
}
return attributes;
}
What should I do to not filter out any attributes of the user object I am trying to retrieve from?
I am aware that Active Directory by default will only shows attributes that are default or have a value in them, I am trying to overcome this limitation.
EDIT 1:
I have temporarily postponed the specific question.
I have been trying to benchmark which of these methods are the fastest at retrieving (READ Operation) the SAM account name of 10.000 individual AD users called for example "testuser", the methods I benchmark are the following:
Time to complete: about 500 msec : ADSI - system.directoryservices
Time to complete: about 2700 msec: Principal - searcher system.directoryservices.accountmanagement
Time to complete: about NOT WORKING :LDAP - System.DirectoryServices.Protocols
Time to complete: about 60 msec : SQL - System.Data.SqlClient
I am querying for the user information from a workstation - Windows 10 machine in the domain I am querying. the workstation (4 vcpu), DC (2vpu) and DB (2vcpu) server is run as Hyper V vm's.

All attributes that any class can have are defined in Active Directory Schema
Use this to query for the user class. Then just call GetAllProperties method
var context = new DirectoryContext(DirectoryContextType.Forest, "amber.local");
using (var schema = System.DirectoryServices.ActiveDirectory.ActiveDirectorySchema.GetSchema(context))
{
var userClass = schema.FindClass("user");
foreach (ActiveDirectorySchemaProperty property in userClass.GetAllProperties())
{
// property.Name is what you're looking for
}
}
However AD schema may vary from one AD environment to another. For example, third party programs or Exchange Server may extend schema with custom attributes. It means that the solution with pre-defined columns will work only for a specific environment.

How to get all installations when using Azure Notification Hubs installation model?

Using NotificationHubClient I can get all registered devices using GetAllRegistrationsAsync(). But if I do not use the registration model but the installation model instead, how can I get all installations? There are methods to retrieve a specific installation but none to get everything.

You're correct, as of July 2016 there's no way to get all installations for a hub. In the future, the product team is planning to add this feature to the installations model, but it will work in a different way. Instead of making it a runtime operation, you'll provide your storage connection string and you'll get a blob with everything associated with the hub.

Sorry for visiting an old thread... but in theory you could use the GetAllRegistrationsAsyc to get all the installations. I guess this will return everything without an installation id as well, but you could just ignore those if you choose.
Could look something like this
var allRegistrations = await _hub.GetAllRegistrationsAsync(0);
var continuationToken = allRegistrations.ContinuationToken;
var registrationDescriptionsList = new List<RegistrationDescription>(allRegistrations);
while (!string.IsNullOrWhiteSpace(continuationToken))
{
var otherRegistrations = await _hub.GetAllRegistrationsAsync(continuationToken, 0);
registrationDescriptionsList.AddRange(otherRegistrations);
continuationToken = otherRegistrations.ContinuationToken;
}
// Put into DeviceInstallation object
var deviceInstallationList = new List<DeviceInstallation>();
foreach (var registration in registrationDescriptionsList)
{
var deviceInstallation = new DeviceInstallation();
var tags = registration.Tags;
foreach(var tag in tags)
{
if (tag.Contains("InstallationId:"))
{
deviceInstallation.InstallationId = new Guid(tag.Substring(tag.IndexOf(":")+1));
}
}
deviceInstallation.PushHandle = registration.PnsHandle;
deviceInstallation.Tags = new List<string>(registration.Tags);
deviceInstallationList.Add(deviceInstallation);
}
I am not suggesting this to be the cleanest chunk of code written, but it does the trick for us. We only use this for debugging type purposes anyways

MVC4 Unit test NSubstitute Could not find a call to return from

I have a MVC4 web application I'm unit testing right now. It uses entity framework for the database portion. I'm using NSubstitute to mock the database. This code is basically copied and pasted from another site which works fine, so I hope I'm just missing something super simple.
Thanks in advance!
Applications table in SQL:
AppID | ApplicationName
----------------------------
1 | MyCoolApplication
2 | MyOtherApplication
Entity created the Application class:
public class Application
{
public int AppID { get; set; }
public string ApplicationName { get; set; }
}
The mock section of the unit test looks like this:
var mockDb = Substitute.For<MyCoolApplicationsEntities>();
var applications = new List<Application>
{
new Application {AppID = 1, ApplicationName = "MyCoolApplication"},
new Application {AppID = 2, ApplicationName = "MyOtherApplication"},
};
var mockApplicationSet = Substitute.For<IDbSet<Application>, DbSet<Application>>();
mockApplicationSet.Provider.Returns(applications.AsQueryable().Provider);
mockApplicationSet.Expression.Returns(applications.AsQueryable().Expression);
mockApplicationSet.ElementType.Returns(applications.AsQueryable().ElementType);
mockApplicationSet.GetEnumerator().Returns(applications.AsQueryable().GetEnumerator());
mockApplicationSet.When(q => q.Add(Arg.Any<Application>()))
.Do(q => applications.Add(q.Arg<Application>()));
mockApplicationSet.When(q => q.Remove(Arg.Any<Application>()))
.Do(q => applications.Remove(q.Arg<Application>()));
mockDb.Applications.Returns(mockApplicationSet); //This is the line creating the error
The full error is:
Test method
MyProjectName.Controllers.MyControllerTest.TestOfSectionImTesting
threw exception:
NSubstitute.Exceptions.CouldNotSetReturnDueToNoLastCallException:
Could not find a call to return from.
Make sure you called Returns() after calling your substitute (for
example: mySub.SomeMethod().Returns(value)), and that you are not
configuring other substitutes within Returns() (for example, avoid
this: mySub.SomeMethod().Returns(ConfigOtherSub())).
If you substituted for a class rather than an interface, check that
the call to your substitute was on a virtual/abstract member. Return
values cannot be configured for non-virtual/non-abstract members.
Correct use:
mySub.SomeMethod().Returns(returnValue);
Potentially problematic use:
mySub.SomeMethod().Returns(ConfigOtherSub());
Instead try:
var returnValue = ConfigOtherSub();
mySub.SomeMethod().Returns(returnValue);
But that doesn't work in my environment because Applications isn't a method. Like I said, this works fine in another site of mine, so it's got to be something basic I'm missing. Nothing I've found online has been helpful with my particular case. I updated to the newest version of NSubstitute and I uninstalled/reinstalled, but still have got nothing.
Again, thanks in advance!

NSubstitute can not mock non-virtual members. (There are quite a few caveats to substituting for classes.)
MyCoolApplicationsEntities.Applications will need to be virtual for .Returns() to work.

Here's what ended up working:
var context = Substitute.For<MyCoolApplicationsEntities>();
var applications = new List<Application>
{
new Application {AppID = 1, ApplicationName = "MyCoolApplication"}
};
var mockApplications = Substitute.For<DbSet<Application>, IQueryable<Application>>();
((IQueryable<Application>)mockApplications).Provider.Returns(applications.AsQueryable().Provider);
((IQueryable<Application>)mockApplications).Expression.Returns(applications.AsQueryable().Expression);
((IQueryable<Application>)mockApplications).ElementType.Returns(applications.AsQueryable().ElementType);
((IQueryable<Application>)mockApplications).GetEnumerator().Returns(applications.AsQueryable().GetEnumerator());
mockApplications.When(q => q.Add(Arg.Any<Application>()))
.Do(q => applications.Add(q.Arg<Application>()));
mockApplications.When(q => q.Remove(Arg.Any<Application>()))
.Do(q => applications.Remove(q.Arg<Application>()));
context.Applications = mockApplications;

I can't see you classes but you need to create interfaces with virtual members and have your code call the class by the interface, then you will be able to mock out the class.

NetSuite custom record search through suiteTalk using C#

We are having an issue with searching a custom record through SuiteTalk. Below is a sample of what we are calling. The issue we are having is in trying to set up the search using the internalId of the record. The issue here lies in in our initial development account the internal id of this custom record is 482 but when we deployed it through the our bundle the record was assigned with the internal Id of 314. It would stand to reason that this internal id is not static in a site per site install so we wondered what property to set up to reference the custom record. When we made the record we assigned its “scriptId’ to be 'customrecord_myCustomRecord' but through suitetalk we do not have a “scriptId”. What is the best way for us to allow for this code to work in all environments and not a specific one? And if so, could you give an example of how it might be used.
Code (C#) that we are attempting to make the call from. We are using the 2013.2 endpoints at this time.
private SearchResult NetSuite_getPackageContentsCustomRecord(string sParentRef)
{
List<object> PackageSearchResults = new List<object>();
CustomRecord custRec = new CustomRecord();
CustomRecordSearch customRecordSearch = new CustomRecordSearch();
SearchMultiSelectCustomField searchFilter1 = new SearchMultiSelectCustomField();
searchFilter1.internalId = "customrecord_myCustomRecord_sublist";
searchFilter1.#operator = SearchMultiSelectFieldOperator.anyOf;
searchFilter1.operatorSpecified = true;
ListOrRecordRef lRecordRef = new ListOrRecordRef();
lRecordRef.internalId = sParentRef;
searchFilter1.searchValue = new ListOrRecordRef[] { lRecordRef };
CustomRecordSearchBasic customRecordBasic = new CustomRecordSearchBasic();
customRecordBasic.recType = new RecordRef();
customRecordBasic.recType.internalId = "314"; // "482"; //THIS LINE IS GIVING US THE TROUBLE
//customRecordBasic.recType.name = "customrecord_myCustomRecord";
customRecordBasic.customFieldList = new SearchCustomField[] { searchFilter1 };
customRecordSearch.basic = customRecordBasic;
// Search for the customer entity
SearchResult results = _service.search(customRecordSearch);
return results;
}

I searched all over for a solution to avoid hardcoding internalId's. Even NetSuite support failed to give me a solution. Finally I stumbled upon a solution in NetSuite's knowledgebase, getCustomizationId.
This returns the internalId, scriptId and name for all customRecord's (or customRecordType's in NetSuite terms! Which is what made it hard to find.)
public string GetCustomizationId(string scriptId)
{
// Perform getCustomizationId on custom record type
CustomizationType ct = new CustomizationType();
ct.getCustomizationTypeSpecified = true;
ct.getCustomizationType = GetCustomizationType.customRecordType;
// Retrieve active custom record type IDs. The includeInactives param is set to false.
GetCustomizationIdResult getCustIdResult = _service.getCustomizationId(ct, false);
foreach (var customizationRef in getCustIdResult.customizationRefList)
{
if (customizationRef.scriptId == scriptId) return customizationRef.internalId;
}
return null;
}

you can make the internalid as an external property so that you can change it according to environment.
The internalId will be changed only when you install first time into an environment. when you deploy it into that environment, the internalid will not change with the future deployments unless you choose Add/Rename option during deployment.

How to make this Unit Testable

Below I have some code that that I cannot Unit test because it tries to read settings from IIS7 and unfortunately our nightly build machine does not have IIS7. The only thing I can think of is to pass the ServerManager into the method, but then again in the caller I will have a ServerManager that will make that method unable to be unit tested. We use MOQ for our Mock library.
public ISection GetCurrentSettings(string location, Action<string> status)
{
#region Sanity Checks
if (string.IsNullOrEmpty(location))
{
throw new ArgumentNullException("location");
}
if (status == null)
{
throw new ArgumentNullException("status");
}
#endregion
ISection section = null;
_logger.Debug(string.Format("Retrieving current IIS settings for app at {0}.", location));
status("Getting current IIS settings.");
using (ServerManager manager = new ServerManager())
{
var data = (from site in manager.Sites
from app in site.Applications
from vdir in app.VirtualDirectories
where vdir.PhysicalPath.Equals(location, StringComparison.CurrentCultureIgnoreCase)
select new {Website = site, App = app}).SingleOrDefault();
if (data == null)
{
_logger.Debug(string.Format("Could not find an application at {0} in IIS. Going to load the defaults instead.", location));
//ToDo possibly load defaults
}
else
{
_logger.Debug(string.Format("Application found in IIS with website: {0} and a path of {1}", data.Website.Name, data.App.Path));
int port =
data.Website.Bindings.Where(b => b.EndPoint != null).Select(b => b.EndPoint.Port).Single();
section = new IISSection
{
ApplicationPoolName = data.App.ApplicationPoolName,
VirtualDirectoryAlias = data.App.Path,
WebsiteName = data.Website.Name,
WebsiteRoot = data.App.VirtualDirectories[0].PhysicalPath,
Port = port.ToString(CultureInfo.InvariantCulture),
WillApply = true,
AnonymousUser = _userService.GetUserByType(UserType.Anonymous)
};
}
return section;
}

Without rewriting your code fully, the general idea would be to pass in an ISettingReader* (implemented as IisSettingReader), which would expose methods that would get the data you need from IIS. Then, you can stub in the ISettingReader to return what you need, by passing ISettingReader into the method/class
*Or, IServerManager as it seems to be the current name, but I am not sure if that is IIS specific
UPDATE
To be more specific, as Darin Dimitrov elaborated, you need to pull all of the dependencies outside of the method and pass them in via parameter/constructor/property injection. This will require a rewrite of the code as it stands in its current state.
If not (and I do suggest a rewrite), then you can use something like TypeMock, which supposedly can fake the dependencies INSIDE a class, but I have not used this myself and only know what I have read on it.

Use Moq.
This will allow you to create a mocked version of ISettings rather than having to create a real one. It has the added advantage of allowing you to specify your own functionality as well.
