Copy a directory recursive

Ultima oara cand a fost nevoie sa fac asa ceva a fost in timpul facultății. In seara asta aveam de lucru la un proiect ce se ocupa cu un deploy si supriza, aveam nevoie de acest mecanism. Speram ca .NET 4.0 sa fie plin de surprize, dar din pacate nu. Asa ca am inceput sa implementez de manuta si uite ce a iesit:
public static class DirectoryHelper
/// Copy recursive a directory to a specific location.

/// Source directory.
/// Destination directory.
public static void Copy(string sourceDirecotry, string destionationDirectory)
if (!Directory.Exists(destionationDirectory))
//Copy all files from the current directory.
foreach (string file in Directory.GetFiles(sourceDirecotry))
var fileName=Path.GetFileName(file);
File.Copy(Path.Combine(destionationDirectory,fileName), Path.Combine(destionationDirectory, fileName));
//Copy files from the subfolders.
foreach (string folder in Directory.GetDirectories(sourceDirecotry))
var directoryName = Path.GetFileName(folder);
Copy(Path.Combine(destionationDirectory,directoryName), Path.Combine(destionationDirectory, directoryName));
M-am gandit si la o varianta LINQ, sa folosesc ForEach si expresii lambda, dar nu e la fel de rapid ca un foreach scris de mana. Un For ar fi si mai rapid, dar nu cred ca e cazul, prefer sa las codul sa fie cat mai usor de inteles. Avantajul la LINQ ar fi fost ca se poate scrie fara apeluri recursive( o sa revin maine si cu varianta aceasta).
Dezamagirea mea a fost in momentul in care am vrut sa il pun ca extension method la System.IO.Directory. Nu se poate asa ceva din cauza ca System.IO.Directory este o clasa statica. Asa ca trebe sa ne multumim cu clase helpere sau sa adaugam aceasta metoda ca extensie la DirectoryInfo.

Atentie, codul nu functioneaza daca unul din path-uri este subpath pentru celalat path. In cazul meu validarea pentru acest caz se face in alt loc.

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine:
threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration:

How to check in AngularJS if a service was register or not

There are cases when you need to check in a service or a controller was register in AngularJS.
For example a valid use case is when you have the same implementation running on multiple application. In this case, you may want to intercept the HTTP provider and add a custom step there. This step don’t needs to run on all the application, only in the one where the service exist and register.
A solution for this case would be to have a flag in the configuration that specify this. In the core you would have an IF that would check the value of this flag.
Another solution is to check if a specific service was register in AngularJS or not. If the service was register that you would execute your own logic.
To check if a service was register or not in AngularJS container you need to call the ‘has’ method of ‘inhector’. It will return TRUE if the service was register.
if ($injector.has('httpInterceptorService')) { $httpProvider.interceptors.push('httpInterceptorService&#…

Fundamental Books of a Software Engineer (version 2018)

More then six years ago I wrote a blog post about fundamental books that any software engineer (developer) should read. Now it is an excellent time to update this list with new entries.

There are 5 different categories of books, that represent the recommended path. For example, you start with Coding books, after that, you read books about Programming, Design and so on.
There are some books about C++ that I recommend not because you shall know C++, only because the concepts that you can learn from it.
