The FromArray method is an extension method for the System.Random class. It allows you to randomly select an element from a given array. If the array is empty or null, it returns a default value specified by the caller.
The FromArray method is an extension method for the System.Random class. It allows you to randomly select an element from a given array. If the array is empty or null, it returns a default value specified by the caller.
To use the FromArray method, you need to have an instance of System.Random. You can then call this method on the instance, passing the array from which you want to select a random element and the default value to return if the array is empty or null.
// Example usage of FromArray method
Random random = new Random();
int[] numbers = { 1, 2, 3, 4, 5 };
int defaultValue = -1;
int randomElement = random.FromArray(numbers, defaultValue);
// randomElement will be a random number from the array or -1 if the array is empty or null.
