C#/.NET Little Wonders: Skip() and Take()
published 414 days, 11 hours, 53 minutes ago posted by BlackRabbitCoderBlackRabbitCoder 419 days, 21 hours, 38 minutes ago
Wednesday, April 04, 2012 10:04:00 AM GMT Friday, March 30, 2012 12:19:05 AM GMT
I’ve covered many valuable methods from System.Linq class library before, so you already know it’s packed with extension-method goodness. Today I’d like to cover two small families I’ve neglected to mention before: Skip() and Take(). While these methods seem so simple, they are an easy way to create sub-sequences for IEnumerable (more)

One of the more radical design decisions in the forthcoming Windows Runtime is that no API may, even potentially, take more than 50 milliseconds to complete. Operations that could take longer than that will instead have a 'kick off this operation' API that returns immediately without waiting for the result of the operation. Discover how this will change how .NET developers write code and what C# 5 includes to take advantage of this new focus on Async. (more)

While the DateTime is a powerful structure for parsing, manipulating, and comparing date-times, it becomes problematic when handling times from different time-zones. The DateTimeOffset is much more portable in that it preserves the offset from UTC. (more)

Inter-Process Communication using MemoryMappingFile
published 451 days, 12 hours, 9 minutes ago posted by abhi2434abhi2434 451 days, 22 hours, 22 minutes ago
Monday, February 27, 2012 9:47:43 AM GMT Sunday, February 26, 2012 11:35:32 PM GMT
In an operating system, a Memory Mapping file are virtual storage place which has direct byte to byte correlation between the Virtual Address Space and the corresponding physical storage. So when we access the Virtual Address space via a memory mapping file we are directly communicating with the kernel space where the file is actually loaded. The portion of calculation between the physical storage and logical storage is hence avoided. Memory Mapping files allows application to access files in the sam... (more)

C#/.NET Little Wonders: The DateTime TryParsae() and ParseExact() Methods
published 501 days, 8 hours, 13 minutes ago posted by BlackRabbitCoderBlackRabbitCoder 503 days, 21 hours, 13 minutes ago
Sunday, January 08, 2012 1:43:59 PM GMT Friday, January 06, 2012 12:44:17 AM GMT
A while back I talked about some goodies in DateTime, mostly the properties that let you split out just the date or time. This week, I wanted to look at a couple more methods of the DateTime struct that give you additional control over parsing an input string into a DateTime. Most of us have dealt with using DateTime.Parse() for these tasks, but sometimes you are wanting to parse something that may not be a valid DateTime, or may be in a non-standard format. So let’s look at the TryParse() and ParseEx... (more)

C#/.NET Fundamentals: Unit Testing with Func Generators
published 514 days, 13 hours, 42 minutes ago posted by BlackRabbitCoderBlackRabbitCoder 517 days, 22 hours, 19 minutes ago
Monday, December 26, 2011 8:15:27 AM GMT Thursday, December 22, 2011 11:38:06 PM GMT
I wanted to attempt a brief post before the holidays, so I decided to quickly revisit part a post I wrote a few weeks back on The Generic Func Delegates, and in particular, the sidebar on using Func as a generator for unit testing. At the time, I did not give that short sidebar the attention I really wanted, including showing the setup of the unit tests and discussing the performance impact (if any) of such a practice. So this week I hope to rectify this by revisiting and enhancing the discussion. (more)

C# Fundamentals: Returning Zero or One Item As IEnumerable
published 529 days, 9 hours, 45 minutes ago posted by BlackRabbitCoderBlackRabbitCoder 531 days, 21 hours, 21 minutes ago
Sunday, December 11, 2011 12:12:15 PM GMT Friday, December 09, 2011 12:36:09 AM GMT
There are times when we are writing a method that returns a sequence of items, that it occasionally becomes necessary in base-class, interface implementation, error, or default conditions to return a sequence of only one or even zero items. There are many ways to do this, of course, which begs the question of which way is best, in terms of readability, maintainability, and performance. (more)

Most .NET developers know about the power of working with Reflection, but when performance becomes an issue what can we do? This post examines the performance benefits of using runtime code generation while noting some of the limitations. This post will give you everything you need to know about choosing between different techniques and when it's right to choose one over the others. (more)

In the last three weeks, we examined the Action family of delegates (and delegates in general), the Func family of delegates, and the EventHandler family of delegates and how they can be used to support generic, reusable algorithms and classes. This week I will be completing my series on the generic delegates in the .NET Framework with a discussion of three more, somewhat less used, generic delegates: Predicate (more)

Back in one of my three original “Little Wonders” Trilogy of posts, I had listed generic delegates as one of the Little Wonders of .NET. Later, someone posted a comment saying said that they would love more detail on the generic delegates and their uses, since my original entry just scratched the surface of them. Last week, I began our look at some of the handy generic delegates built into .NET with a description of delegates in general, and the Action family of delegates. For this week, I’ll launch i...

Friday, October 21, 2011 1:09:31 AM GMT
Previously, I had created some posts about the Task Parallel Library’s Concurrent Collections – which are very efficient collections designed for concurrent use with minimal contention – but in this next series of Little Wonders posts, I’d like to explore the parts of the TPL that can simplify and improve the way you perform parallel programming. For this week, we are going to start looking at the Parallel static class’s, For() static method, which is a quick and easy way to perform parallel processing ... (more)

C#/.NET Toolbox: Creating a "Safer" Task Dispose()
posted by BlackRabbitCoderBlackRabbitCoder 594 days, 21 hours, 4 minutes ago
Friday, October 07, 2011 12:52:42 AM GMT
So recently, I’ve been moving some older utility classes logic over to use the excellent .NET Task Parallel Library (TPL). This library contains, at it’s core, a class called Task which allows parallel programming without the need of working directly with threads. During this process, I wrote a few extension methods I found to be useful in dealing with tasks in an easier manner, and thought I’d share them in a few posts. Today's will discuss an extension method to make disposing a task a little bit "sa... (more)

Well, now getting deeper into the facts, lets talk about how objects are created in .NET and how type system is laid out in memory for this post in my Internals Series.  As this is going to be very deep dive post, I would recommend to read this only if you want to kill your time to know the internal details of .NET runtime and also you have considerable working experience with the CLR types and type system. Recently I have been talking with somebody regarding the actual difference between the C++ t... (more)

C#/.NET Little Wonders: String Padding and Trimming - Not Just for Spaces!
posted by BlackRabbitCoderBlackRabbitCoder 608 days, 21 hours, 57 minutes ago
Friday, September 23, 2011 12:00:30 AM GMT
I’m going to wrap up my little side excursion into the String class with just a quick post on two features we’ve probably all used from time to time, but with a little twist: padding and trimming. Yes, we’ve probably all padded strings with spaces and numbers with zeros before, or trimmed off extra spaces, but did you know these methods aren’t just confined to whitespace? (more)

C#/.NET Little Wonders: The String Remove() and Replace() Methods
posted by BlackRabbitCoderBlackRabbitCoder 615 days, 22 hours, 16 minutes ago
Thursday, September 15, 2011 11:41:02 PM GMT
When manipulating string data, many times you want to either remove parts of a String or replace characters in a String. You can do this yourself, of course, by building a new String while manually inspecting each char in turn, but this gets to be a bit expensive and is less maintainable. Instead, there are two methods in the String class, ready to use, that let you do this easily: Remove() and Replace(). (more)
