[译文]c#扩展方法(Extension Method In C#) 原文链接: https://www.codeproject.com/Tips/709310/Extension-Method-In-Csharp 介绍 扩展方法是C# 3.0引入的新特性。扩展方法使你能够向现有类型“添加”方法,而无需创建新的派生类型、重新编译或以其他方式修改原始类型。 扩展方法是一种
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 ...
You can take advantage of extension methods to add additional functionality — integers, strings, chars, etc. — to existing types in C#. For example, the code snippet below illustrates how you can extend the string class in C# to add a new method that returns the count of non-space chara...
这是在C# 3.0中定义Extension Method而引入的关键字。添加了这样一个关键字就意味着在调用该方法的时候这个标记有this的参数可以前置,从而允许我们向调用一般Instance Method的方式来调用这个Static Method。注意:需要在(只需要在)第一个参数前面使用this修饰。 Extension Method IN CLR C# 3.0的这些新的特性大都影响Sou...

The public instance method (ExtensionMethod) is defined in the extension class. It's available as if it were defined in MyClass in the context of the model where the extension class is defined. The following example shows how to call the method in the model. X++ 复制 MyClass c = new...

Method of Obtaining Device-Side Data:获取终端设备侧的位置数据,可以选择从日志中解析(Log scraping),或者选择手动输入(Manual input)。选择从日志中解析时,需要您将工程运行起来后,点击“Start”,工具会弹出一个窗口展示从日志中解析出的位置数据列表,选择相应的位置数据后点击“Capture”即可抓取该条位置数据,并注入...
