I am using automapper 7.0.1 with .Net core 2.1.



This class converts to 



public class Item

{

    public long Id { get; set; }

    public int? CurrencyId { get; set; }



    public Location Location { get; set; } = null;

}



public class ItemLocation 

{

    public long Id { get; set; }



    public string Address { get; set; }



    [NotMapped]

    public Translation Translations { get; set; }



    public bool IsPrivate { get; set; } = false;                 



    public IList<ItemLocationUserDefined> UserDefinedItemLoacation { get; set; }



    [NotMapped]

    public float Latitude { get; set; }



    [NotMapped]

    public float Longitude { get; set; }

}


Converts to :



public class ItemsToReturnDto

{

    public long Id { get; set; }

    public int? CurrencyId { get; set; }



    public LocationDto Location { get; set; } = null;

}



public class ItemLocationToReturnDto

    {

        public long Id { get; set; }



        public string Address { get; set; }



        public Translation Translations { get; set; }



        public float Latitude { get; set; }



        public float Longitude { get; set; }



        public bool IsUserDefined { get; set; }



        public DateTimeOffset UpdatedAt { get; set; }



        public DateTimeOffset CreatedAt { get; set; }

        public bool Disabled { get; set; }

    }


I have initialized Automapper in startup.cs 



var mappingConfig = new MapperConfiguration(mc =>

{

    mc.AllowNullDestinationValues = true;

    mc.AddProfile(new MappingProfile());

});



IMapper mapper = mappingConfig.CreateMapper();

services.AddSingleton(mapper);


Mapping profile :



CreateMap<ItemsToReturnDto, Item>()

                .ForMember(dest => (int)dest.Status, opts => opts.MapFrom(src => src.Status))

                .ReverseMap();

CreateMap<ItemLocationToReturnDto, ItemLocation>()

                .ForMember(dest => dest.IsPrivate, opts => opts.MapFrom(src => src.IsUserDefined))

                .ReverseMap();


But even if source Location object is null Automapper automatically initialize empty Location object.



How I can return null if source is null?

  • No, you just have to do the work to isolate the issue. That might be difficult, but it would prove the problem is with AM, not with your own code.

  • You need to add the classes Location, LocationDto and MappingProfile, without these there is not enough to look at this properly as no one can reproduce it

count number of partitions of a set with n elements into k subsets

up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k? NOTE->I know this is not the best way to calculate number of partitions that would be DP // A C++ program to count number of partitions // of a set with n elements into k subsets #include<iostream> using namespace std; // Returns count of different partitions of n // elements in k subsets int countP(int n, int k) { // Base cases if (n == 0 || k == 0 || k > n) return 0; if (k == 1 || k == n) return 1; // S(n+1, k) = k*S(n, k) + S(n, k-1) return k*countP(n-1, k) + countP(n-1, k-1); } // Driver program int ma

A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

Image
0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
