Trie implementation: Search method with weird return value

I am fairly new to C# and working on a project in which I need to build a prefix tree (trie). Searching in the trie should return a list of words matching a given search prefix.
That's the code I have so far, but the search doesnt actually return the value I'm looking for and instead returns "Trees.PrefixTree+d__5". What am I doing wrong or what do I have to change to get it run?
Thank you very much in advance!

Try changing your Console.WriteLine() to this:
Console.WriteLine(string.Join(", ", trie.Search("te")));
You were not concatenating all the strings together!

WMI Invalid Query in C# but works in wbemtest utility

I am trying to create a WQLEventQuery to run in a C# applet that triggers whenever a new folder is created within a specified folder. I have used WMI before and I am familiar with how it works. I successfully created the same type of eventquery for when a new file is added to a specific folder. The weird part is that I get an exception when running the applet in debugging, but if I take the same query and run it from the 'wbemtest' utility built into windows, no 'invalid query' is thrown when I remove the Within clause. However, if I do not set the WithinInterval property on the WQLEventQuery object in C# code, a different exception is thrown related to the polling interval being required. Here are some Code snippets for context:

So the query string is essentially
"select * from __InstanceCreationEvent within 1 where TargetInstance isa 'Win32_SubDirectory' And TargetInstance.GroupComponent = 'Win32_Directory.Name=C:\\MonitoredDocs'"
If take that query string and remove the within clause, wbemtest accepts it as a valid WMI query. When the within clause is present, it says it is an invalid query. I am using an answer from this article. Any help to figure out how to get this WQL Event Query to work would be appreciated.

So I read through the article that I posted above with a more focused attention, and found an alternate query that actually works. The query string looks like this:
Select * From __InstanceCreationEvent Within 1 Where TargetInstance Isa 'Win32_Directory' And TargetInstance.Drive = 'C:' And TargetInstance.Path = '\\path\\to\\monitored\\directory\\'
*One detail that can be confusing is that that the path value has to contain the trailing "\\"
in terms of code, my modified FolderMonitor.cs class looks like this: (changes marked with *!*!*)
public class FolderMonitor : IWQLMonitor
{
private const string _eventClassName = "__InstanceCreationEvent";
*!*!*private const string _isaType = "Win32_Directory";*!*!*
private readonly IEventListenerManager _eListenerManager;
private readonly IFileProcessService _fileProcessService;
public WqlEventQuery Query { get; }
public string Path { get; }
public FolderMonitor(string path, IEventListenerManager eListenerManager, IFileProcessService fileProcessService)
{
_eListenerManager = eListenerManager;
_fileProcessService = fileProcessService;
if (string.IsNullOrEmpty(path))
path = GetConfiguredDirectory();
Path = path;
*!*!*var drive = Path.Substring(0, 2);*!*!*
*!*!*var queryPath = Path.Substring(2) + #"\";*!*!*
var queryParamPath = queryPath.Replace(#"\", #"\\");
Query = new WqlEventQuery
{
EventClassName = _eventClassName,
*!*!*Condition = $"TargetInstance Isa '{_isaType}' And TargetInstance.Drive = '{drive}' And TargetInstance.Path = '{queryParamPath}'",*!*!*
WithinInterval = new TimeSpan(0,0,1)
};
}

Use Rhino Mock to report the function that was called

I have a failing testcase that depends on an external module.
I want to use Rhino Mock to generate a report on called functions.
I created a minimal example that illustrates my problem:
using NUnit.Framework;
using Rhino.Mocks;
using System;
namespace StackOverflow_namespace
{
public interface IUsefulService
{
object HiddenAmongManyCalls();
}
public class ThirdPartyBase
{
private int a = 42;
public ThirdPartyBase(IUsefulService service)
{
object liveFastDieYoung = service.HiddenAmongManyCalls();
liveFastDieYoung.Equals(a);
}
}
public class MyParty : ThirdPartyBase
{
public MyParty(IUsefulService service) : base(service)
{
}
}
[TestFixture]
class StackOverflow
{
[Test]
public void Hypothetical()
{
IUsefulService service = MockRepository.GenerateMock<IUsefulService>();
try
{
var party = new MyParty(service);
}
catch(Exception e)
{
string[] calls = MagicallyGetTheCallsThatWereMadeToTheMock();
foreach(var call in calls)
{
//with my visual studio testrunner for nunit 3 I can investigate stored console output
Console.WriteLine(call);
}
Assert.Fail("Excpexted no exception but was '" + e.GetType().Name + "': " + e.Message);
}
}
private string[] MagicallyGetTheCallsThatWereMadeToTheMock()
{
return new[]
{
"This is where I am lost, I do not know how to get the calls from the repository."
};
}
}
}
I tried to find something online without success.
Do Rhino Mocks record all calls and can I access that list?
Edit:
An attempt to verify Expectations did not work since I am looking for calls I did not expect.
I could build a list of calls using GetArgumentsForCallsMadeOn. I can reflect on the Interface. I started on a method for that but I currently fail to see how I can convert a MethodInfo to an Action<T>.
private IEnumerable<string> GetCallsList<Interface>(Interface rhinomock)
{
Type interfaceType = typeof(Interface);
List<MethodInfo> interfaceMethodInfos = new List<MethodInfo>();
List<string> returnInfos = new List<string>();
StringBuilder callbuilder = new StringBuilder();
foreach (var property in interfaceType.GetProperties())
{
interfaceMethodInfos.Add(property.GetGetMethod());
interfaceMethodInfos.Add(property.GetSetMethod());
}
foreach (var method in interfaceType.GetMethods())
{
interfaceMethodInfos.Add(method);
}
foreach (var methodinfo in interfaceMethodInfos)
{
Action<Interface> magic = null; //convert methodinfo into action - still missing
var calls = rhinomock.GetArgumentsForCallsMadeOn(magic); //magic is currently null, here be crash
foreach (var call in calls)
{
bool more = false;
callbuilder.Clear().Append(interfaceType.Name).Append('.').Append(methodinfo.Name).Append('(');
foreach (var parameter in call)
{
if (more){ callbuilder.Append(", "); }
if (null == parameter) { callbuilder.Append("<null>"); }
else { callbuilder.Append(parameter.ToString()); }
more = true;
}
callbuilder.Append(')');
string callInfo = callbuilder.ToString();
returnInfos.Add(callInfo);
}
}
return returnInfos;
}

I was able to use reflection to get the output I wanted.
Here is the minimal example where the test fails and the output contains all method calls.

public ThirdPartyBase(IUsefulService service)
{
service.TestCall2("callA", 1);
service.TestCall2("callB", 1);
object liveFastDieYoung = service.HiddenAmongManyCalls();
service.TestCall2("callA", 2);
service.TestCall2("callB", 2);
var a = service.FULLACCESS;
var b = service.READONLY;
service.FULLACCESS = "some";
liveFastDieYoung.Equals(a);
}

Lync API: How to send instant message to contact by email address?

I have the email address of a Lync user and want to send him an instant message.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Lync.Model;
using Microsoft.Lync.Model.Conversation;
namespace Build_Server_Lync_Notifier

{
if (args.Length != 2)
{
Console.WriteLine("Usage: bsln.exe <uri> <message>");
return;
}
LyncClient client = Microsoft.Lync.Model.LyncClient.GetClient();
Contact contact = client.ContactManager.GetContactByUri(args[0]);
Conversation conversation = client.ConversationManager.AddConversation();
conversation.AddParticipant(contact);
Dictionary<InstantMessageContentType, String> messages = new Dictionary<InstantMessageContentType, String>();
messages.Add(InstantMessageContentType.PlainText, args[1]);
InstantMessageModality m = (InstantMessageModality) conversation.Modalities[ModalityTypes.InstantMessage];
m.BeginSendMessage(messages, null, messages);
//Console.Read();
}
}
}
Screenshot
Link to large screenshot: http://i.imgur.com/LMHEF.png
As you can see in this screenshot, my program doesn't really seem to work, even though I'm able to manually search up the contact and send an instant message manually.
I also tried using ContactManager.BeginSearch() instead of ContactManager.GetContactByUri(), but got the same result (you can see in the screenshot): http://pastie.org/private/o9joyzvux4mkhzsjw1pioa

Ok, so I got it working now. Got it in a working state, although I need to do some serious refactoring.

}

{
object[] asyncState = (object[]) r.AsyncState;
ContactManager cm = (ContactManager) asyncState[0];
try
{

if (results.AllResults.Count == 0)
{
Console.WriteLine("No results.");
}
else if (results.AllResults.Count == 1)
{
ContactSubscription srs = cm.CreateSubscription();
Contact contact = results.Contacts[0];
srs.AddContact(contact);
ContactInformationType[] contactInformationTypes = { ContactInformationType.Availability, ContactInformationType.ActivityId };
srs.Subscribe(ContactSubscriptionRefreshRate.High, contactInformationTypes);
_conversation = _client.ConversationManager.AddConversation();
_conversation.AddParticipant(contact);
Dictionary<InstantMessageContentType, String> messages = new Dictionary<InstantMessageContentType, String>();
messages.Add(InstantMessageContentType.PlainText, _message);
InstantMessageModality m = (InstantMessageModality)_conversation.Modalities[ModalityTypes.InstantMessage];

}
else

Console.WriteLine("More than one result.");
}
}
catch (SearchException se)

}
_client.ContactManager.EndSearch(r);
}
private void BeginSendMessageCallback(IAsyncResult r)
{

}

Try Below Code its working Fine For me

}
private static void SendLyncMessage()
{

foreach (string target in targetContactUris)
{
conv.AddParticipant(client.ContactManager.GetContactByUri(target));
}
InstantMessageModality m = conv.Modalities[ModalityTypes.InstantMessage] as InstantMessageModality;
m.BeginSendMessage("Test Message", null, null);
}

How can I write HTML in a Word document?

In the WriteHeader I write some text on the document header, but I need to use HTML. How can I say the contents are HTML? I will also need to insert HTML in the document content...

I can just insert the html file on the section I want using:
range.InsertFile("file.html");
