Question

I got this List :

private static List<Type> _AbstractTypes = new List<Type>();

and later in my project I got a string that corresponds to a Type.FullName.
The thing is that I’d like to check if my string is contained in my List but I don’t manage to avoid a loop usable 🙁
Im looking for something like :

_AbstractTypes.FullName.Contains(myString)

I am absolutely aware that my previous code is not compilable at all but that’s the sort of thing im looking for !
Thanks in advance for any help

You can use Linq, but we are talking about loop-less construct here only, the code under the hood must do a loop, if you want to do it better, you could use HashSet<T>.

Linq code could look like this:

_AbstractTypes.Any(t => t.FullName == myString);

HashSet<Type> code could look like this:

var types = new HashSet<Type>();
types.Add(typeof(int)); //Fill it with types
types.Add(typeof(double));

//Check by getting types from their string name, you could of course also cache those types
Console.WriteLine("Contains int: " + types.Contains(Type.GetType(intName))); //True
Console.WriteLine("Contains float: " + types.Contains(Type.GetType(floatName))); //False
