How to write better code for several for each loops in c# / ASP.NET / EF Core-CodePudding

i want to know how to write a better code then the below. It works, but i think there has to be a better way to write it. Maybe with some Lambda expressions ?

var dataList = new List<MyModel>();

        foreach (var data in dataArray)
        {
            var model = new MyModel();
            model.Name = data.Name;
            model.LastName = data.LastName;
            
            model.Model = "";
            model.SubModel = "";

            if (data.Cars.Any())
            {
                foreach (var car in data.Cars)
                {
                    model = new MyModel();
                    model.Name = data.Name;
                    model.LastName = data.LastName;
                    model.Model = car.Model;
                    model.SubModel = "";

                    if (car.SubModels.Any())
                    {
                        foreach (var subModel in car.SubModels)
                        {
                            model = new MyModel();
                            model.Name = data.Name;
                            model.LastName = data.LastName;
                            model.Model = car.Model;
                            model.SubModel = subModel.Model;
                            dataList.Add(model);
                        }
                    }
                    else
                    {
                        dataList.Add(model);
                    }
                }
            }
            else
            {
                dataList.Add(model);
            }
        }

Tried to convert it to Lync in VS

CodePudding user response：

pseudo code not tested. You need also three constructors to create the model class. Or you do it with property init:

new Model() { Name = data.Name, 
LastName = data.LastName, Model = car.Model, SubModel = subModel.Model}

        var dataList = dataArray
          .Select(item => item.Cars)
              .Select(car => new Model(data.Name,data.LastName,car.Model,subModel.Model))
          .Concat(item => item.SubModel
                    .Select(subModel => new Model(data.Name,data.LastName,car.Model,subModel.Model,subModel.Model)))
          .Concat(dataArray.Select(data => new Model(data.Name,data.LastName)))
