I have a list of objects in which every object is containing a list itself. how do I get the the JellyFishID field or the Amount field for using an IF argument (I'm currently using Foreach):`
public static List<Report> DataSorted = new List<Report> {
new Report() { IsGoldUser=true, Date=new DateTime(2016, 3, 12,11, 59, 33), IsBurningWater=true, Type=Type.Shore, ZoneID = 1 ,
ReportDetails =new List<ReportDetail> { new ReportDetail() { Amount = Amount.Few, Jellyfish = new Jellyfish { JellyfishID = 1, Venom = Venom.Strong } } } },
new Report() { IsGoldUser=true, Date=new DateTime(2016, 3, 12, 11, 59, 33), IsBurningWater=true, Type=Type.Shore, ZoneID = 1 ,
ReportDetails =new List<ReportDetail> { new ReportDetail() { Amount = Amount.Few, Jellyfish = new Jellyfish { JellyfishID = 1, Venom = Venom.Strong } } } },
new Report() { IsGoldUser=true, Date=new DateTime(2016, 3, 12, 11, 59, 33), IsBurningWater=true, Type=Type.Shore, ZoneID = 1 ,
ReportDetails =new List<ReportDetail> { new ReportDetail() { Amount = Amount.Few, Jellyfish = new Jellyfish { JellyfishID = 1, Venom = Venom.Strong } } } },
new Report() { IsGoldUser=true, Date=new DateTime(2016, 3, 12, 11, 59, 33), IsBurningWater=true, Type=Type.Shore, ZoneID = 1 ,
ReportDetails =new List<ReportDetail> { new ReportDetail() { Amount = Amount.Few, Jellyfish = new Jellyfish { JellyfishID = 1, Venom = Venom.Strong } } } },
foreach (var item in DataSorted)
{
if (item.ReportDetails....) //???I want here to Make an Argument about The Amount field or the JellyFishID field in the list above....
}
You don't describe exactly what you want to check, but with LINQ to Objects you have a lot of possiblities. At first, you need to reference the correct namespace with
using System.Linq;
at the top of your source code file.
Now, if you want to check if any items of your list contains a jellyfish with a given ID, you can use:
if (item.ReportDetails.Any(t => t.Jellyfish.JellyfishID == 1)) //...
Additionally you can have conditions inside a Where-function to filter your list and search only for jellyfish with a few amount:
if (item.ReportDetails.Where(t => t.Amount == Amount.Few).
Any(t => t.Jellyfish.JellyfishID == 1)) //...
There is a lot of information avaliable about LINQ, a lot of examples are in the MSDN (for example this intro page), but there are alternatives like this one: 101 Linq examples. It even has a tag on StackOverflow.
