CodeSmith编写ibatisnet生成模板

首先新建一个实例模板文件

<%@ CodeTemplate Language="C#" TargetLanguage="Xml" ResponseEncoding="UTF-8" Description="Template description here." %>

声明该模板文件使用的模板语言

<%@ Property Name="assemblyname" Type="System.String" Default="SomeValue" Optional="True" Category="Strings" Description="This is a sample string property." %>
<%@ Property Name="SourceTable" Type="SchemaExplorer.TableSchema" Category="Context" Description="Table that the mapping file is based on" %>

声明属性的作用是为了给用户自定义声明

<%@ Assembly Name="SchemaExplorer" %>
<%@ Assembly Name="System.Data" %>
<%@ Import Namespace="SchemaExplorer" %>
<%@ Import Namespace="System.Data" %>

<script runat="template">
    public string ToLowercase(string str)
    {
        str = str.ToLower();    
        return str;
    }
    
</script>

script标签一般是用来声明方法

<?xml version="1.0" encoding="UTF-8" ?>
