Mapping
|
// create destination from data from source
var destination = source.Adapt<Destination>();
// update destination with data from source
source.Adapt(destination);
|
Configuration
|
|
// global config
TypeAdapterConfig.GlobalSettings.Default.IgnoreNullValues(true);
// config the mapping from Item to ItemDto
TypeAdapterConfig<Item, ItemDto> // src, dest
.NewConfig() // create new map config (overwrite existing ones)
.ForType() // OR create a map config if no one exists, otherwise append to th existing one
.Ignore(dest => dest.Prop1) // do not map Prop1
.Map(dest => dest.Prop2, src => $"{0} {1}", src.Prop2, src.Prop3)); // custom mapping for Prop2
|
IRegister
| Program.cs |
// scan the assembly to get the classes implementing IRegister
TypeAdapterConfig.GlobalSettings.Scan(typeof(ItemMappingRegister).Assembly);
|
| MappingRegisters/ItemMappingRegister.cs |
public class ItemMappingRegister : IRegister
{
public void Register(TypeAdapterConfig config) => config.NewConfig<CreateUpdateItemRequest, Item>();
}

Dependency Injection
 |
Useful is you migrate from Automapper to Mapster and you do not want to change your code. |
|
dotnet add package Mapster.DependencyInjection |
| Program.cs |
services.AddSingleton(config);
services.AddScoped<IMapper, ServiceMapper>();
|
Installation
|
|
dotnet add package Mapster |
