How to check if a Set is Empty in C# ?

Answer

To check if a Set is empty in C#, you can use the Count property or the Any method.

✐ Examples

1 Check if Set is Empty Using Count Property

In this example,

We define a set named `mySet` containing elements of a specific type.
We check if the count of elements in the set is equal to zero using the `Count` property.
If the count is zero, then the set is empty; otherwise, it contains elements.

C# Program

// Define set
HashSet<int> mySet = new HashSet<int>();

// Check if set is empty using Count property
if (mySet.Count == 0) {
    Console.WriteLine("Set is empty");
} else {
    Console.WriteLine("Set is not empty");
}

Output

Set is empty

2 Check if Set is Empty Using Any Method

In this example,

We define a set named `mySet` containing elements of a specific type.
We use the `Any` method to check if the set contains any elements.
If the `Any` method returns `false`, then the set is empty; otherwise, it contains elements.

C# Program

// Define set
HashSet<int> mySet = new HashSet<int>();

// Check if set is empty using Any method
if (!mySet.Any()) {
    Console.WriteLine("Set is empty");
} else {
    Console.WriteLine("Set is not empty");
}

Output

Set is empty
