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。
目前创新互联公司已为上千的企业提供了网站建设、域名、网络空间、绵阳服务器托管、企业网站设计、赣州网站维护等服务,公司将坚持客户导向、应用为本的策略,正道将秉承"和谐、参与、激情"的文化,与客户和合作伙伴齐心协力一起成长,共同发展。
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CodePlex http://agilemapper.codeplex.com/代码):
- StudenDo stu = new StudenDo()
- {
- ID = 1,
- Name = "test1",
- Sex = Sex.女,
- Address = new Address()
- {
- Country = "中国",
- Province = "四川",
- Street = "高新区"
- },
- CourseIds = new List
() { "1", "2", "3" }, - Propertys = new List

- {
- Phone = "1111111111111111",
- Email = "xxxx@12f",
- QQ = "7889789999889"
- }
- };
- Func
fun = (f, j) => f.ID == j.ID; - var s = fun.ToString();
- var mapper = ObjectMapperManager.Default.GetMapper
(); - mapper.AgileMapperTemplateStrategy.DefaultEqualExpression = "{0}.ID == {1}.ID && {1}.ID != 0";
- var str1 = mapper.CodeGenerator();
- System.IO.File.Delete(@"E:\Project\OpenSource\AgileMapper\AgileMappper.Test\CodeTemplate.Test\1.cs");
- System.IO.File.AppendAllText(@"E:\Project\OpenSource\AgileMapper\AgileMappper.Test\CodeTemplate.Test\1.cs", str1);
- var mapper1 = ObjectMapperManager.Default.GetMapper

- System.IO.File.Delete(@"E:\Project\OpenSource\AgileMapper\AgileMappper.Test\CodeTemplate.Test\2.cs");
- System.IO.File.AppendAllText(@"E:\Project\OpenSource\AgileMapper\AgileMappper.Test\CodeTemplate.Test\2.cs", str1);
- var mapper2 = ObjectMapperManager.Default.GetMapper
