pattern is a very effective means of providing a nice boundary around a set of core classes while at the same time allowing for functional change. This article will demonstrate how the visitor pattern

The constructor is a method with no return type https://www.c-sharpcorner.com/article/C-Sharp-object-instantiation-part-i-constructors/https://www.c-sharpcorner.com/article/C-Sharp-object-instantiation-part-i-constructors/Sun, 24 Jun 2007 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)In a recent article comment I was asked for a sample of how to use a delegate and so I wanted to put together a sample of how we can use delegates in order to implement a strategy pattern in a way thahttps://www.c-sharpcorner.com/article/a-strategy-for-using-delegates-in-C-Sharp/https://www.c-sharpcorner.com/article/a-strategy-for-using-delegates-in-C-Sharp/Fri, 15 Jun 2007 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)In my last article I discussed a general approach to building an async architecture. In this article we’ll look at extending this basic architecture and incorporating async web services. https://www.c-sharpcorner.com/article/multi-threaded-asynchronous-programming-in-C-Sharp-through-the-webpage-part5/https://www.c-sharpcorner.com/article/multi-threaded-asynchronous-programming-in-C-Sharp-through-the-webpage-part5/Sun, 27 May 2007 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)Before .NET 2.0, I found myself frequently creating custom EventArgs classes just to return a value from an event and would end of with a lot of extra classes bloating my code base that all basically had the same purpose.https://www.c-sharpcorner.com/article/custom-generic-eventargs/https://www.c-sharpcorner.com/article/custom-generic-eventargs/Mon, 14 May 2007 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)This is a continuation of a set of articles on Asynchronous multi-threaded development using C#. In this article we'll cover the basics of building an event-driven architecture which will be a basis for most multi-threaded apps. Also we'll cover async read/write operations on a file.https://www.c-sharpcorner.com/article/multi-threaded-asynchronous-programming-in-C-Sharp-event-drive/https://www.c-sharpcorner.com/article/multi-threaded-asynchronous-programming-in-C-Sharp-event-drive/Mon, 14 May 2007 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)In my last couple articles we looked at basic ways to have long-running i/o bound process be handled by the ThreadPool using the asynchronous programming model. In this article we’ll take a look at coding async calls against SqlServer which really comes in handy in production environments where our database is on another machine.https://www.c-sharpcorner.com/article/multi-threaded-asynchronous-programming-in-C-Sharp-async-databa/https://www.c-sharpcorner.com/article/multi-threaded-asynchronous-programming-in-C-Sharp-async-databa/Mon, 14 May 2007 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)In this article we'll dig a bit deeper into what is actually happening when we use the asynchronous calls using C#. Just as in my previous article, we'll simulate a long running I/O bound process as if we were fetching records from a database, making a web service call or reading or writing from a file and see how we can write more performant code by letting the main thread continue on and not wait for the results. https://www.c-sharpcorner.com/article/C-Sharp-asynchronous-multi-threaded-development-digging-in-p/https://www.c-sharpcorner.com/article/C-Sharp-asynchronous-multi-threaded-development-digging-in-p/Sun, 13 May 2007 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)Trying to build better solutions and growing as a developer has always been fun for me and I’m always looking for ways to build more scalability and robustness in the software I am writing. I had a revelation that I’ve been doing a lot of C# tweaking but not taking advantage of the core performance enhancements cooked right into C# and it all comes down to one thing: Asynchronous multi-threaded programming.https://www.c-sharpcorner.com/article/multi-threaded-asynchronous-programming-in-C-Sharp-getting-sta/https://www.c-sharpcorner.com/article/multi-threaded-asynchronous-programming-in-C-Sharp-getting-sta/Sat, 12 May 2007 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)The Chain of Responsibility pattern is used to pass responsibility for handling a call to another class.

To do this, we can write "observer"-type interfaces for notification, subscription and un-subscription to events because the VB.Net event model is based on the Observer GOF pattern.http://www.vbdotnetheaven.com/UploadFile/rmcochran/defensiveEvents11152006065023AM/defensiveEvents.aspxhttp://www.vbdotnetheaven.com/UploadFile/rmcochran/defensiveEvents11152006065023AM/defensiveEvents.aspxThu, 16 Nov 2006 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)Boolean logic often fails to adequately simulate real-world conditions because things are never simply just black and white (or zeroes and ones) but exist in millions of shades of grey.

It's primary purpose is to separate the definition for an API from the implementation. This keeps the API flexible by enabling the core functionality to be flexible and easily changed.https://www.c-sharpcorner.com/article/the-net-2-0-framework-provider-pattern/https://www.c-sharpcorner.com/article/the-net-2-0-framework-provider-pattern/Fri, 11 Aug 2006 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)For this article, we’ll be building an exciting calculation engine that does remarkable things like adding, subtracting, multiplying and dividing through implementation of the strategy pattern.https://www.c-sharpcorner.com/article/introduction-to-the-gof-strategy-pattern-in-C-Sharp/https://www.c-sharpcorner.com/article/introduction-to-the-gof-strategy-pattern-in-C-Sharp/Tue, 08 Aug 2006 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)This article covers the basics of the GOF Abstract Factory design pattern by looking at building Model T automobiles. https://www.c-sharpcorner.com/article/the-gof-abstract-factory-design-pattern-in-C-Sharp/https://www.c-sharpcorner.com/article/the-gof-abstract-factory-design-pattern-in-C-Sharp/Fri, 04 Aug 2006 00:00:00 GMTnoreply@c-sharpcorner.com (Matthew Cochran)This article covers overriding the System.Random object in order to produce better random numbers.
