Initializing an array filled with a repeated non-default value

suggest change

As we know we can declare an array with default values:

int[] arr = new int[10];

This will create an array of 10 integers with each element of the array having value 0 (the default value of type int).

To create an array initialized with a non-default value, we can use Enumerable.Repeat from the System.Linq Namespace:

  1. To create a bool array of size 10 filled with “true”
    bool[] booleanArray = Enumerable.Repeat(true, 10).ToArray();
  2. To create an int array of size 5 filled with “100”
    int[] intArray = Enumerable.Repeat(100, 5).ToArray();
  3. To create a string array of size 5 filled with “C#”
    string[] strArray = Enumerable.Repeat("C#", 5).ToArray();
