C# Linq 如何使用 object 的数据筛选列表并将结果存储在另一个列表中？

Question

Structure of my object

int capacityNeeded, string preferedNeigborHood, string[] resourcesNeeded (object property is of type IEnumerable <string)

6, "Centro", new[] { "wi-fi", "tv" }

Structure of my office list

string LocationName, string Name, int MaxCapacity, IEnumerable AvailableResources

Structure of my location list string Name, string Neighborhood

I need to compare that object with a list containing multiple offices and return the office containing the preferences by returning the closest one, my list does not necessarily contain the same resources and contains different capabilities and I need to return the closest one, and my list of offices does not have the neighborhood, but it has the name of the location and the location list has the neighborhood, I understand the logic to implement, but what I really need is how to write the code, for example I can obtain the offices that contain the necessary capacity, as well as the location that contain the preferred neighborhood, but I don't know how to get the offices that contain the resources, and taking into account that it may have the resources I need and others, eg my preference is {"wi-fi", "tv"} and I have an office that has {"wi-fi", "tv", "coffe"} I should return that one since it has my preference.

I add that both the preferedNeigborHood and the resourcesNeeded can be null

A bit of the code i wrote

public IEnumerable<IOffice> GetOfficeSuggestion(SuggestionRequest suggestionRequest)
{
    var resources = suggestionRequest.ResourcesNeeded;

    if (resources.Count() == 0 
        || string.IsNullOrEmpty(suggestionRequest.PreferedNeigborHood))
    {
        var officeSuggestion = offices
                        .Where(x => x.MaxCapacity >= suggestionRequest.CapacityNeeded)
                        .OrderBy(o => o.MaxCapacity);

        foreach (var office in officeSuggestion)
        {
            var list = new OfficeDto
            {
                Name = office.Name,
                LocationName = office.LocationName,
                MaxCapacity = office.MaxCapacity,
                AvailableResources = office.AvailableResources
            };

            _suggestionsOffice.Add(list);
        }

        return _suggestionsOffice;
    }
    else
    {
        var officeSuggestion = offices
                        .Where(x => x.MaxCapacity >= suggestionRequest.CapacityNeeded)
                        .OrderBy(o => o.MaxCapacity);

        foreach (var office in officeSuggestion)
        {
            var list = new OfficeDto
            {
                Name = office.Name,
                LocationName = office.LocationName,
                MaxCapacity = office.MaxCapacity,
                AvailableResources = office.AvailableResources
            };

            _suggestionsOffice.Add(list);
        }

        return _suggestionsOffice;
    }
}

made this test project check it out link

    public class Program
{
    public static List<Office> offices = new List<Office>(){
    new Office{
    LocationName = "test",
    MaxCapacity = 6,
    AvailableResources = new[]{"wi-fi", "tv", "FHD", "Smth"}
    },
        new Office{
    LocationName = "test",
    MaxCapacity = 8,
    AvailableResources = new[]{"wi-fi", "tv", "FHD", "Smth"}
    }
    ,
    new Office{

    };
    
    public static void Main()
