c# check if list contains type code example

Example 1: c# object is in object list

public class A { public int Id {get;set;} public A() {} public A(int id) {Id = id;}}

List<A> list = new List<A>() { new A() { Id = 1}, new A() { Id = 2}};

bool containsItem = list.Any(item => item.Id == 3);
// this would return false.

Example 2: list contains type c#

if (within.OfType<Ball>().Any())

Example 3: c# check list of objects for value

var matches = myList.Where(p => p.Name == nameToExtract);
