ToolsCodeTemplate使用

最近学习使用CodeSmith代码生成器

CodeSmith 是一种语法类似于get='_blank'>asp.net的基于模板的代码生成器，程序可以自定义模板，从而减少重复编码的劳动量，提高效率。

作用：CodeSmith 是一种基于模板的代码生成工具，它使用类似于ASP.NET的语法来生成任意类型的代码或文本。与其他许多代码生成工具不同，CodeSmith 不要求您订阅特定的应用程序设计或体系结构。使用 CodeSmith，可以生成包括简单的强类型集合和完整应用程序在内的任何东西。

当您生成应用程序时，您经常需要重复完成某些特定的任务，例如编写数据访问代码或者生成自定义集合。CodeSmith 在这些时候特别有用，因为您可以编写模板自动完成这些任务，从而不仅提高您的工作效率，而且能够自动完成那些最为乏味的任务。CodeSmith 附带了许多模板，包括对应于所有 .NET 集合类型的模板以及用于生成存储过程的模板，但该工具的真正威力在于能够创建自定义模板。

应用：CodeSmith 是一种语法类似于asp.net的基于模板的代码生成器，程序可以自定义模板，从而减少重复编码的劳动量，提高效率。

安装CodeSmith 2.6注册后发现有两个可运行程序CodeSmith Studio.exe和CodeSmith Explorer.exe

CodeSmith Studio.exe用来创建自定义模板

CodeSmith Explorer.exe用来导入模板并且生成代码

打开 CodeSmith Studio.exe，新建一个C#模板。发现有如下类似与asp.net的标识符号

<% %>

<%= %>

<%@ %>

<script runat="template"> </script>
