. NET Platform Open source project quick glance-the fastest object mapping component Tiny Mapper Project practice

Mood small: Recently changed work, bitter force in 22:00 after work, room a messy ~ small Cui despise to: "You are suitable for living in the garbage heap!!!" "

Visit the blog in the evening to see a very useful blog:. NET Platform Open Source project Quick glance (14) Fastest object mapping component tiny Mapper, took 10 minutes to get a quick look.

It is also valuable to see comments, and many novice students are asked to use the situation in the actual project.

The following is a slight adjustment on the basis of the original author's code to illustrate the use of the actual project scenario:

Step One: Understanding Class Library methods: Tinymapper has two main functions:

Tinymapper.bind<t1, t2> ();//Binding mapping relationship

Tinymapper.map<t> (obj);//Get the desired object from the object

Step Two: Initialize the mapping settings

Description: Similar mapping settings are nothing more than two modes: code static object initialization mode, XML configuration mode, and it is an honor to Tinymapper support a static dictionary.

 Public Static classTinymapcontext { Public Static voidinitmapping () {Tinymapper.bind<person, persondto>(); Tinymapper.bind<person, persondto> (config ={config. Ignore (x= X.id);//Ignore ID fieldConfig. Bind (x = x.name, y = y.username);//bind the field of the source type and the target type to matchConfig. Bind (x = x.age, y = y.age);//bind the field of the source type and the target type to match            }); Tinymapper.bind<person, persondto> (config ={config. Ignore (x= X.id);//Ignore ID field//bind the field of the source type and the target type to matchConfig. Bind (x = x.name, y = =y.username); Config. Bind (x= = X.age, y =y.age); Config. Bind (x= = x.address, y =y.address); Config. Bind (x= = X.emails, y =y.emails);            }); Tinymapper.bind<PersonDto,Person>(); Tinymapper.bind<PersonDto,Person> (config ={config. Bind (x= x.id,y=>y.id); Config. Bind (x= = X.username, y =y.name); Config. Bind (x= = X.age, y =y.age);            }); Tinymapper.bind<PersonDto,Person> (config ={config. Bind (x= X.id,y=>y.id);//Ignore ID field//bind the field of the source type and the target type to matchConfig. Bind (x =>x.username,y=>y.name); Config. Bind (x= = X.age, y =y.age); Config. Bind (x= = x.address, y =y.address); Config. Bind (x= = X.emails, y =y.emails);        }); }         Public StaticT getmapobject<t> (ObjectMB ()whereT:class        {           returnTinymapper.map<t>(obj); }    }

Description: In the above mapping mapping, for the original author code, added: by persondto= "person" mapping relationship.

The role of the where T:class in T getmapobject<t> (object obj) is reflected in the code that follows. A simple method, the power can not be small hush ~ ~

Step three: Dtomodel-"Model

Mapping from a database model to a domain model:

var p = tinymapcontext.getmapobject<person> (persondto);

Fourth step: model-"Dtomodel

From the domain model to the database model:

var persondto = tinymapcontext.getmapobject<persondto> (person);

Fifth Step:list<model>=>list<dtomodel> or list<dtomodel>=>list<model>

        /// <summary>        ///The test List object. /// </summary>        Static voidTest4 () {List<Person> personlist =NewList<person>(){            NewPerson {Id=Guid.NewGuid (). ToString (), Name="John1", Age= A, Address=NewAddress () {Phone ="1880393", Street ="Shanghai", ZipCode ="121212"}, Emails=Newlist<string> () {"[email protected]","[email protected]" }            },            NewPerson {Id=Guid.NewGuid (). ToString (), Name="John2", Age= A, Address=NewAddress () {Phone ="1880393", Street ="Shanghai", ZipCode ="121212"}, Emails=Newlist<string> () {"[email protected]","[email protected]" }            },              NewPerson {Id=Guid.NewGuid (). ToString (), Name="John3", Age= A, Address=NewAddress () {Phone ="1880393", Street ="Shanghai", ZipCode ="121212"}, Emails=Newlist<string> () {"[email protected]","[email protected]" }            },              NewPerson {Id=Guid.NewGuid (). ToString (), Name="John4", Age= A, Address=NewAddress () {Phone ="1880393", Street ="Shanghai", ZipCode ="121212"}, Emails=Newlist<string> () {"[email protected]","[email protected]" }            }            }; varPersondtolist = tinymapcontext.getmapobject<list<persondto>>(personlist); foreach(varIteminchpersondtolist) {Debugoutpututil.debugoutput (item.            UserName); }            varPList = tinymapcontext.getmapobject<list<person>>(persondtolist); foreach(varIteminchpList) {Debugoutpututil.debugoutput (item.            Name); }        }

Special note: For objects that get list types, you do not need to add additional IList-type objects in the static initialization mappings. Tinymapper automatically helps you get the data you want based on the "mapped underlying type" dynamically.

Description: The code is easy to understand, but people are not perfect, coding is not standard place, hand error, or code has defects, or serious performance problems, I hope the friends of the park to criticize.
