AutoMapper Enum to byte with implemention IMapperConfigurator

AutoMapper Enum to byte with implemention IMapperConfigurator

Here's an example of how to configure AutoMapper to map an enum to a byte using the IMapperConfiguration interface:

using AutoMapper; class Program { static void Main(string[] args) { var config = new MapperConfiguration(cfg => { cfg.CreateMap<MyEnum, byte>().ConvertUsing(s => (byte)s); }); IMapper mapper = config.CreateMapper(); MyEnum myEnumValue = MyEnum.Value1; byte byteValue = mapper.Map<byte>(myEnumValue); Console.WriteLine(byteValue); // Output: 1 } } public enum MyEnum : byte { Value1 = 1, Value2 = 2, Value3 = 3 }

In this example, we create a new MapperConfiguration object and use the CreateMap method to configure a mapping between the MyEnum enum type and the byte type. We then use the ConvertUsing method to specify a custom conversion from MyEnum to byte.

Finally, we create a new IMapper object by calling the CreateMapper method on the MapperConfiguration object, and use it to map a MyEnum value to a byte value using the Map method.

Note that in this example, we have specified a custom conversion using a lambda expression to cast the MyEnum value to a byte. This lambda expression is passed to the ConvertUsing method as an argument.

You can customize this mapping by using a different lambda expression or by implementing a custom ITypeConverter or IValueConverter class.
