Created page with "Category:MVC Category:Core == Installation == Command line dotnet add package AutoMapper dotnet add package AutoMapper.Extensions.Microsoft.DependencyInjection --v..."

New page

[[Category:MVC]]
[[Category:Core]]

== Installation ==
Command line
dotnet add package AutoMapper
dotnet add package AutoMapper.Extensions.Microsoft.DependencyInjection --version 1.2.0
PM>
Install-Package AutoMapper
== Add to Dependency Injection ==
In startup.cs -> ConfigurationServices add this line
services.AddAutoMapper();
add
using AutoMapper;
== usage ==
inject as '''IMapper mapper'''
public MakesController(VegaDbContext context, IMapper mapper)
...

Map like below. First parameter is source second is target and in parentheses, we provide the object
mapper.Map<List<Make>, List<MakeResource>>(makes)

== Mapping Profile ==
'''Profile''' is in '''AutoMapper''' namespace
<pre class="brush:CSharp;">
public class MappingProfile : Profile
{
public MappingProfile
{
CreateMap<Make, MakeResource>();
CreateMap<Model, ModelResource>();
}
}
Mapping profile is loaded during startup
</pre>
