AutoMapper: Mapping Value Types with Null Values

CreateMap<SaveMaterialDto, Material>().Ignore(x => x.Id).ForAllMembers(opt => opt.Condition((src, dest, sreMember, dMember) => sreMember != null));

This code snippet illustrates how to prevent mapping when a string property is 'null'. However, for value types like 'int', 'bool', and 'float', the mapping process handles null values automatically. When the source value is 'null', value types are assigned their default values. For instance, an 'int' property will be mapped to 0, and a 'bool' property will be mapped to 'false' when the source value is 'null'.

Consequently, you don't need to explicitly define conditions for value types in your mapping configuration. AutoMapper will automatically map them to their default values.
