AutoMapper使用

var c = new C1() { ID = 1, Name = 2 };
var d = new C2() { ID = 3, CName = 4, Des = 3 };
var im = Mapper.CreateMap<C1, C2>();
im.ForMember(f => f.CName, cname => cname.MapFrom(c1 => c1.Name));
im.ForMember(g => g.Des, des => des.MapFrom(a => a.ID));
var e = Mapper.Map<C1, C2>(c);
Assert.AreEqual(c.ID,e.Des);
Assert.AreEqual(e.CName,c.Name);

Mapper.CreateMap<C1, C2>().ForMember(f => f.CName, cname => cname.MapFrom(c1 => c1.Name)).ForMember(f => f.CName, cname => cname.MapFrom(c1 => c1.Name)).ForMember(g => g.Des, des => des.MapFrom(a => a.ID));
