AutoMapper auto create createMap in C#

AutoMapper is a mapping library for .NET that allows you to easily map objects between different types. AutoMapper uses convention-based mappings by default, which means that it will automatically map properties with the same name and type between objects.

To create a mapping between two types using AutoMapper's convention-based mappings, you can use the CreateMap method of the MapperConfiguration class. Here's an example of how to create a mapping between two types using AutoMapper's convention-based mappings:

using AutoMapper;

// Define the source and destination types
public class SourceType
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class DestinationType
{
    public int Id { get; set; }
    public string Name { get; set; }
    public bool IsProcessed { get; set; }
}

// Configure AutoMapper
var config = new MapperConfiguration(cfg => {
    cfg.CreateMap<SourceType, DestinationType>();
});

// Use AutoMapper to map objects
var source = new SourceType { Id = 1, Name = "John" };
var destination = mapper.Map<DestinationType>(source);

In this example, we define a source type SourceType and a destination type DestinationType. We then create a new MapperConfiguration object and use the CreateMap method to create a mapping between the SourceType and DestinationType types.

Once the mapping is configured, we can use the Mapper.Map method to map objects between the two types. In this example, we create a new SourceType object and map it to a DestinationType object using AutoMapper.

When using AutoMapper's convention-based mappings, you do not need to explicitly create a mapping for every source/destination type pair. Instead, AutoMapper will automatically create a mapping based on the conventions it uses. However, you can still customize the mapping behavior or create explicit mappings for specific type pairs using the CreateMap method.
