Yes, it is possible to retrieve a collection of Enums while excluding one using Linq.
To exclude a specific Enum value, you can use the Where
method in Linq with a condition that checks if the Enum value is not equal to the excluded value.
For example, let's say you have an Enum called Fruit
with values Apple
, Banana
, Orange
, and Pear
and you want to retrieve a collection of all fruits except for Orange
. You can use the following code:
var allFruitsExceptOrange = Enum.GetValues(typeof(Fruit))
.Cast<Fruit>()
.Where(fruit => fruit != Fruit.Orange)
.ToList();
In this code, Enum.GetValues(typeof(Fruit))
retrieves an array of all possible values for the Enum Fruit
. The Cast<Fruit>()
method converts this array to a collection of Fruit
objects. The Where
method is then used to filter out any Fruit
values that are equal to Fruit.Orange
. Finally, the ToList()
method is used to convert the filtered results to a List of Fruit
values.
