Daca avem doua liste si este nevoie sa facem merge la elemente doua cate doua in ordinea pozitiei din lista este nevoie sa scriem un cod asemanator cu acesta:
var numeList = new[] { "Ioan", "Gheorghe", "Mihai", "Laurentiu" };
var prenumeList = new[] { "Pop", "Rus", "Ratiu", "Negru" };
var numePrenumeList = new List<string>();
for(int i = 0; i < numeList.Count(); i++)
numePrenumeList.Add(numeList[i] + " " + prenumeList[i]);

Rezultatul ar fi:
Ioan Pop
Gheorghe Rus
Mihai Ratiu
Laurentiu Negru
Acelasi lucru putem sa il facem daca folosim metoda Enumerable.Zip. Prin intermediul acestei metode putem sa facem merge intre doi vectori element cu element:
var numePrenumeList = numeList.Zip(
(nume, prenume) => nume + " " + prenume);
Nu o sa avem nevoie de acesta metoda in fiecare zi, dar mi s-a parut o metoda pe care merita sa o cunoastem.
In cazul in care lungimea la cei doi vectori nu este aceiași, o sa se faca merge doar pana la MIN(lista1.Count,lista2.Count). Desi parca ar fi mai normal sa arunce exceptie.

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.
