Writing object to object mapper: my mapper vs AutoMapper

As my object to object mapper is now almost completed and I am sure it is good idea to stay on LCG (Lightweight Code Generation) I can now compare the performance of my mapper to AutoMapper. (more)

A Tale of Two Principle Violations

由

KodefuGuru 发表于 29 天, 9 小时, 8 分钟之前

When I decided to write the With statement in Fluent.NET, I never imagined that I would encounter a common bug and school myself in principles that I happen to present on. But that is what occurred, and I want to share it so others can avoid the same mistakes I made. With is a Fluent version of Add, only it returns the object or interface it is acting upon rather than void. This allows you to chain methods together in a fluid manner. Instead of calling strings.Add(“Hello”); strings.Add(“World”);, you ca... (more)

Writing object to object mapper: first implementations

I wrote some object to object mapping code and introduced it in some of my previous postings about performance. As I received 22x performance raise when trying out different mapping methods it is now time to make my code nice. In this posting I will show you how I organized my code to classes. Yes, you can use my classes in your work if you like. (more)

Performance: Using LCG to copy property values of two objects

Today I gave last performance boost to my property values copying mechanism. I would like to thank my readers Ron and David to remind me Lightweight Code Generation (LCG) and pointing me out aussie bloke blog entry Generic copy object using Lightweight Code Generation. In this posting I will show you last performance boost and put down a summary about my experiment this far. (more)

CodeProject: Introduction to PayPal for C# - ASP.NET developers.

PayPal is probably one of the first things that gets mentioned once discussion on online payments starts. It’s not so without reason – in 2008 PayPal moved over 60 billion dollars between accounts which is, you’ll agree, respectable amount. And also, all trends show that this growth will continue – with huge number of new accounts (over 184 million accounts in 2008 compared to 96.2 million in 2005), with new platform named PayPal X and with more cool applications that involve paying (like Twitpay) you ca...

Zero Server Controls technique in ASP.Net, C# (XML Insertion, JavaScript tricks using AJAX deletion and XSLT record display using JavaScript)

Introduction: In this article I have explained about "Zero Server controls technique". I have implemented the new record insertion using the XML data type. For deletion of the record I have used the JavaScript tricks and Ajax. The record display in the table format, I have chosen the XML and XSLT. I have explained the Dynamic HTML technique using the Ajax techniques. But this time I have chosen this XSLT transformation technique. (more)

Guide to Improving Code Performance in .NET: Part II

In this article, we will look into handling errors in an optimistic way. Handling of errors is quite common task in any kind of programming language. Most of the modern languages like C++, C# uses similar kind of exception handling constructs. We will see how to handle exceptions without any performance impact on the application by examples. I will be using VS 2008 with C# as language for all the samples. (more)

.Net Framework 4.0: C# and optional arguments and named parameters - Gunnar Peipman's ASP.NET blog

C# 4.0 supports optional method arguments. Related to this is support for named parameters in function calles. For us it makes easier to use methods which have long argument list. It also introduces some new dangers which may lead us to messy and hard to understand code. In this code I will show how to use optional arguments and give some hints how to avoid messy code. (more)

Unit testing is an integral part of any software that is developed. It is an advantage which most of us are either not aware of or we are neglecting it.

In other words it defines that an object must be able to notify other objects without making assumptions about what these objects are. Observer design pattern is quite useful when a change to one object requires changing others but, you don't know how many objects need to be changed.Using Observer Design Pattern in Blog Subscriber...

【转载】C# 委托的妙文

xgluxv 发表于 240 天, 7 小时, 8 分钟之前

委托和事件在 .Net Framework中的应用非常广泛，然而，较好地理解委托和事件对很多接触C#时间不长的人来说并不容易。它们就像是一道槛儿，过了这个槛的人，觉得真是太容易了，而没有过去的人每次见到委托和事件就觉得心里别（biè）得慌，混身不自在。本文中，我将通过两个范例由浅入深地讲述什么是委托、为什么要使用委托、事件的由来、.Net Framework中的委托和事件、委托和事件对Observer设计模式的意义，对它们的中间代码也做了讨论。将方法作为方法的参数我们先不管这个标题如何的绕口，也不管委托究竟是个什么东西，来看下面这两个最简单的方法，它们不过是在屏幕上输出一句问候的话语：以下为引用的内容： public void GreetPeople(string name) { // 做某些额外的事情，比如初始化之类，此处略 EnglishGreeting(name); } public void EnglishGreeting(string name) ...
