如果你还不了解Green.AgileMapper的用意,作用请先一步到上篇Green.AgileMapper开源项目的使用,如果你觉得运行时(Runtime)的Mapper效率存在问题,在这个版本中有了更新,新增了C#直接代码的生成,这里的生成都已3.0后的扩展方法实现,你可以很方便的一句代码实现两者的转化。
代码生成我本想利用T4模板,但是由于我们的项目IDE版本是VS2008,对于T4的参数传递支持还不是很友好,你可能说用AppDomain.SetData,或者CallContext.LogicalSetData,但是可惜我们的饿MappingRule是不可序列化的,所以最后我只得采用了字符串拼接最笨的办法,为了应对生成策略不同,在这里我们加入了策略模式来应付,来看看代码结构吧:
在这里只支持对do的二级属性映射为dto的平面属性,全部针对IMappingRule生成代码,在这里为了生成合法的代码而非表达式,对以前的表达式进行了重新的标准约定,在代码注释。以及对上个版本的List转换进行了多次重载,主要为了满足DTo到DO对象的特殊要求,因为我们在领域开发存储DTO的时候都是需要先取出DO对象在根据DTO在DO对象的基础上进行修改,以便ORM领域框架或者UOW的跟踪记录。
下面看看任然是上个测试类模型的代码生成(在这里测试DO,DTO类进行了重构为了更全面的测试,具体请看CodePlexhttp://agilemapper.codeplex.com/代码):
{
ID = 1,
Name = "test1",
Sex = Sex.女,
Address = new Address()
{
Country = "中国",
Province = "四川",
Street = "高新区"
},
CourseIds = new List<string>() { "1", "2", "3" },
Propertys = new List<KeyValuePair>() { new KeyValuePair() { Key = "1", Value = "1" } },
ContactWay = new ContactWay()
{
Phone = "1111111111111111",
Email = "xxxx@12f",
QQ = "7889789999889"
}
};
Func<StudenDo, StudenDo, bool> fun = (f, j) => f.ID == j.ID;
var s = fun.ToString();
var mapper = ObjectMapperManager.Default.GetMapper<StudenDto, StudenDo>();
mapper.AgileMapperTemplateStrategy.DefaultEqualExpression = "{0}.ID == {1}.ID && {1}.ID != 0";
var str1 = mapper.CodeGenerator();

在这里的代码生产后很乱并未格式化处理,需要我们在VS中自动Ctrl+K+D格式,如果你希望生成时候就帮助格式化了的话,你可以参见工具CoolFormat源代码格式化,安装工具利用CMD命令批量格式化(可以参见百度百科:http://baike.baidu.com/view/4367725.htm)。在项目暂不会考虑这块,如果你有兴趣的可以先帮助成,谢谢。
具体请参见项目,存在任何问题或者bug可以随时给我留言,谢谢。项目地址CodePlex http://agilemapper.codeplex.com/
