.NET - Nice to have

In C# la crearea unui obiect putem sa inițializam propietatiile acestuia prin următoarea sintaxa:

Engine engine=new Engine(…)
{
Power = 101,
Type = “ES12RW120TDI”
};
Am simtit uneori nevoie sa pot face acelasi lucre si cu un obiect deja creat. Exista locuri cand obiectul este initalizat de un factory sau deja exista, si trebuie sa schimbam valoarea unor proprietati. Mi-ar placea sa pot face urmatorul lucru:
Engine engine = InitEngine(…)
{
Power = 101,
Type = “ES12RW120TDI”
};
sau
use (engine)
{
Power = 101,
Type = “ES12RW120TDI”
};
In loc de
engine.Power = 101;
engine.Type = “ES12RW120TDI”;
Nu cred ca o sa vad vreodată acest feature si nici din punct de vedere a unui limbaj de programare sintaxa nu este tocmai corecta, dar ar fi nice to have, uneori ne-ar putea usura putin codul.

  1. Treci la VB http://msdn.microsoft.com/en-us/library/wc500chb.aspx :-D

    Ce as fi vrut eu la chestia asta este sa poti sa bagi si eventuri acolo. E aiurea un cod care arata asa:
    var x=new X {
    A='a',
    B='b'
    };
    x.E+=e;
    x.F+=f;

  2. Exact - in VB(.Net) exista dintotdeauna asa ceva, dar e mai mult un sintactic sugar care face codul sa arate ciudat..

    In 3 ani de zile de folosit VB am evitat with in general - in primul rand fiindca with in VB permitea cod arbitrar in interior, si se ajungea la carnatzi de 50 de linii in care nu mai stiai de ce obiect tine un property, de genul:
    With alertLabel
    If value = 0 Then
    .ForeColor = draw.Color.Red
    .Font = New draw.Font(.Font, draw.FontStyle.Bold Or draw.FontStyle.Italic)
    Else
    .Forecolor = draw.Color.Black
    .Font = New draw.Font(.Font, draw.FontStyle.Regular)
    End If
    End With

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 http://go.microsoft.com/fwlink/?LinkId=260882 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:

GET call of REST API that contains '/'-slash character in the value of a parameter

Let’s assume that we have the following scenario: I have a public HTTP endpoint and I need to post some content using GET command. One of the parameters contains special characters like “\” and “/”. If the endpoint is an ApiController than you may have problems if you encode the parameter using the http encoder.
using (var httpClient = new HttpClient()) { httpClient.BaseAddress = baseUrl; Task<HttpResponseMessage> response = httpClient.GetAsync(string.Format("api/foo/{0}", "qwert/qwerqwer"))); response.Wait(); response.Result.EnsureSuccessStatusCode(); } One possible solution would be to encode the query parameter using UrlTokenEncode method of HttpServerUtility class and GetBytes method ofUTF8. In this way you would get the array of bytes of the parameter and encode them as a url token.
The following code show to you how you could write the encode and decode methods.

Entity Framework (EF) TransactionScope vs Database.BeginTransaction

In today blog post we will talk a little about a new feature that is available on EF6+ related to Transactions.
Until now, when we had to use transaction we used ‘TransactionScope’. It works great and I would say that is something that is now in our blood.
using (var scope = new TransactionScope(TransactionScopeOption.Required)) { using (SqlConnection conn = new SqlConnection("...")) { conn.Open(); SqlCommand sqlCommand = new SqlCommand(); sqlCommand.Connection = conn; sqlCommand.CommandText = ... sqlCommand.ExecuteNonQuery(); ... } scope.Complete(); } Starting with EF6.0 we have a new way to work with transactions. The new approach is based on Database.BeginTransaction(), Database.Rollback(), Database.Commit(). Yes, no more TransactionScope.
In the followi…
