Extension methods in C# enable you to add methods to existing types without creating a new derived type, recompiling, or otherwise modifying the original type.
扩展方法定义在静态类(static classes)里,就像静态方法(static methods)一样,但是它们在CLR元数据(CLR metadata)里却被标记为[System.Runtime.CompilerServices.Extension]。程序语言都被鼓励(encourage)为扩展方法提供一种直观的语法(direct syntax)。在 C# 语言里,扩展方法是由 this 指针(this modifer)标示(indicate)...
Extension methods are a new feature for C# 3.0 and I had the opportunity to implement them in the Compiler. These methods can then be called with instance syntax on any object that is convertible(see convertibility section for details) to the first param of the method.Validation Extension ...
C#之 VS2008 之 Extension Methods~(为变量添加自己的方法) 从ScottGu's Blogs上看到了关于Vs2008中.NET Framework3.5语言(Jeffry Zhao说这是 C#3.0的特性,自己见识太短了)的新特性,其中有一个叫做Extension Methods http://weblogs.asp.net/scottgu/archive/2007/03/13/new-orcas-language-feature-extension-met...
They allow you to tack on new methods to existing classes for which you don’t own the original code. Now C++ does not support this natively and so I recently got bit when I was translating some C# code into C++ CLI. While C# gave me nice Intellisense C++ did not The method I was...
Controversial extension methods: You’ve probably had to do this in C#. You get an object, you need to cast it to some typeTand then fetch a property that is returned as anobject, so you have to castthatto some other typeU, so you can read the destination property....

It can also be a serious nuisance if you muddy a namespace with what many developers might consider superfluous methods. If you added 50 extension methods to the C#stringclass, then developers who just want to access the base functionality of that object would always have to contend with your...
Extension methods to fluently assert the outcome of .NET tests Fluent Assertions provides a comprehensive set of extension methods that enable developers to express the expected outcomes of TDD (Test-Driven Development) and BDD (Behavior-Driven Development) unit tests in a natural, readable style. ...
