I have a list of foo called crepes. I want to return foo where bar.doritos == "coolRanch"
class foo
{
List<bar> item;
string candy;
string beer;
}
class bar
{
string doritos;
string usb;
}
var item = crepes.item.Where(x => x.doritos == "coolRanch").FirstOrDefault();
From other threads, i've pieced together the above linq query, but crepes.item throws an error. "List does not contain a definition for 'item' and no definition for 'item' accepting first argument...
Given that crepes is a List<Foo>, you need to add an additional level to the linq query.
var item = crepes.Where(a => a.item.Any(x => x.doritos == "coolRanch")).FirstOrDefault();
Your item access modifier is private (this is C# default for class), it should be made public
This goes for your doritos too
Also, since your crepes is a List, put additional layer of LINQ (as also suggested by others) to completely fix it, something like this
var item = crepes.Where(f => f.item.Any(b => b.doritos == "coolRanch")).FirstOrDefault(); //f is of foo type, b is of bar type
If you fix your classes like this
class Foo
{
public List<Bar> Items { get; set; }
public string Candy { get; set; }
public string Beer { get; set; }
}
class Bar
{
public string Doritos { get; set; }
public string Usb { get; set; }
}
Your query will look like
var crepes = new List<Foo>();
var item = crepes.FirstOrDefault(f => f.Items.Any(b => b.Doritos == "coolRanch"));
Here, we are trying to get the first Foo which has at least one Bar in Items where Doritos == "coolRanch".
C#are private by default. Change your declaration topublic List<bar> item;
