C# - Adding data to list inside list

Question

How can I add the following data on the table into a list called Vehicles?

public class criterias
{
    public double values { get; set; }
    publi         


        

Answer 1

You can fill your list by moving from top to bottom, like

• Create Criterias List then Create movChannel object and add that list to Criterias object and so on

However if you want to avoid this way, there is another way. If you are using Linq To List then follow this

Get a simple flat object to a list object

var TableData = db.Tablename.Tolist(); 

Then fill your own object like this

Vehicles finalList = TableData.Select(a => new Vehicles()
{
    vehID = a.Id,
    vehDescription = a.des,
    vehValCriteria = TableData.Where(b => b.StepslistId == a.StepslistId)
    .Select(c => new StepsList()
    {
                steps = c.Steps,
                stepChannelsCriteria = TableData.Where(d => d.channelId == c.channelId)
                .select(e => new MovChannels()
                {
                    name = e.name,
                    criteria = TableData.Where(f => f.criteriasId = e.criteriasId)
                    .Select(g => new Criterias()
                    {
                        values = g.Values,
                        time = g.Time

                    }).ToList()
                }).ToList()
         }).ToList()
    }).ToList();

This is standard way to fill list within list
