CodeSmith批量代码生成并存放到指定目录

其实CodeSmith自带的例子是很好的学习材料，其中一个例子就有批量生成所有表(指定表)并存放到指定目录的，但例子还是归例子，要符合实际需要的使用，还是得改一下的。下面发布下本人修改后的批量生成多种模板多个表的代码文件，并存放到指定目录下：

            }
         return  mResult.ToString();
    }
</ script >

其实，这个批量输出的可以重复使用的，只需要把模板拷贝到对应的模板目录中后，修改变量TemplateNames、strFormats、OutputPaths为自己实际需要的参数就能应用到不同的模板库中了，十分方便，如果看官们的模板参数不一样，那就得修改“//统一属性赋值”下的SetProperty相关的属性就可以了。
