AutoMapper Object Mapping Tool: The main point is to turn one entity into another.

1. Refer to NuGet packages; Search: AutoMapper

2. Create an entity class

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;namespaceautomapper{ Public Static classautomapperextension {/// <summary>        ///Single Object Mapping/// </summary>        /// <typeparam name= "TSource" >Source Object</typeparam>        /// <typeparam name= "Tdestination" >target Object</typeparam>        /// <param name= "source" ></param>        /// <returns></returns>         Public StaticTdestination Mapto<tsource, tdestination>(TSource source) {if(Source = =NULL)return default(tdestination); Mapper.initialize (x= X.createmap (typeof(TSource),typeof(tdestination))); returnMapper.map<tdestination>(source); }        /// <summary>        ///Collection List Type mappings/// </summary>        /// <typeparam name= "TSource" >Source Object</typeparam>        /// <typeparam name= "Tdestination" >target Object</typeparam>        /// <param name= "source" ></param>        /// <returns></returns>         Public StaticList<tdestination> Maptolist<tsource, Tdestination> ( ThisIenumerable<tsource>source) {            if(Source = =NULL)return default(list<tdestination>); Mapper.initialize (x= X.createmap (typeof(TSource),typeof(tdestination))); returnMapper.map<list<tdestination>>(source); }    }}

3. As an example. Create two Entity objects

(Old member entity)

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;namespaceautomapper{ Public  classUsermodel {/// <summary>        ///member Number/// </summary>         PublicInt32 UserId {Get;Set; } /// <summary>        ///member name/// </summary>         PublicString Name {Get;Set; } }}

New Member Entity

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;namespaceautomapper{/// <summary>    ///New Membership Form/// </summary>     Public classUsernewmodel {/// <summary>        ///member Number/// </summary>         PublicInt32 UserId {Get;Set; } /// <summary>        ///member name/// </summary>         PublicString Name {Get;Set; } }}

4. How to use it. In the process of the project. If you need to convert two of entities. Working with instances

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;namespaceautomapper{ Public classExtension {/// <summary>        ///turn user into usernew/// </summary>         Public Static voidModel () {varuser =NewUsermodel () {UserId=1, Name="Wang Bin"            }; varUsernew =NewUsernewmodel (); //transfer old member entity to new member entity            varU = automapperextension.mapto<usermodel,usernewmodel>(user); }         Public Static voidmodellist () {List<UserModel> Users =NewList<usermodel>(); varuser =NewUsermodel () {UserId=1, Name="Wang Bin"            };            Users.add (user); varUsernew =NewList<usernewmodel>(); //transfer old member entity to new member entity            varUlist = Automapperextension.maptolist<usermodel, usernewmodel>(Users); }    }}
