In GroovyConfigSlurper is a utility class that is used for reading configuration files written in form of Groovy scripts.Let’s consider the following properties file. We will use a Groovy script to read from this properties file as shown in the snippet below: package com.test import java.util.Properties class Start { static main(args) { def p = new Properties() new File("test.properties").withInputStream { stream -> p.load(stream) } println "gfv3.admin....

As you know till now in c# everything was static and known at design time. But with the C# 4.0 language Microsoft have enabled new dynamic data type which is belongs to Dynamic Language Runtime on top of CLR(Common language Runtime).

Implementation of an Observer

abhi2434 1001 days, 2 hours, 19 minutes ago

Hi Folks, As few people told me to implement an observer in my last post where I just showed how to use it, here is the post where I am going to clear out confusions for you. If you have read my other post, you might already know what is an Observer and why it is required. Lets recap this a bit more. An observer is a container which observes each element individually and notifies you when the object state is modified. The observer should contain methods that enables you to subscribe or unsubscrib... (more)

Subspace .NET Blog | Getting rid of null checks in property chains with - but not limited to - AutoMapper and S#arpArchitecture

posted by

http://sandord.myopenid.com/ 1018 days, 7 hours, 30 minutes ago

As I was doing some entity to DTO mapping using AutoMapper, I found myself writing a lot of null checks when mapping nested properties. Those checks are often necessary because one or more properties in the chain may be null. For example, string zipCode = customer.Address.ZipCode; may throw a NullReferenceException when either customer or Address is null. This is often handled by writing code like this: string zipCode = (customer != null ? (customer.Address != null ? (customer.Address.ZipCode... (more)

With this post I want to start a series devoted to the new parallel programming features in .NET Framework 4 and introduce you the Task Parallel Library (TPL). I have to admit that I’m not an expert in multithreading or parallel computing. However, people often ask me about easy introductions and beginner’s samples for new features. And I have an enormous advantage over most newbies in this area – I can ask people who developed this library about what I’m doing wrong and what to do next... (more)

C# 4.0 dynamic keyword for Dummies – Under the hood

In this post, we’ll go back to the basics to uncover few interesting aspects of C# 4.0 dynamic features. Let us start with a simple experiment. Static Typing or Early Binding Let us start with a bare minimum program. Fire up VS2010 and try the following code. It is obvious that this won’t compile. Simply because, the compile/design time checking ensures type safety - and as we don’t have a method named SomeStupidCall in our Human class, we can’t compile the same. So, that is what you get.
