The FromList method is an extension method for the System.Random class. It allows you to randomly select an element from a List<T>. If the list is empty, it returns a default value specified by the caller.
The FromList method is an extension method for the System.Random class. It allows you to randomly select an element from a List<T>. If the list is empty, it returns a default value specified by the caller.
To use the FromList method, you need to have a System.Random instance and a List<T> from which you want to select a random element. You also need to provide a default value of type T that will be returned if the list is empty.
Example usage:
System.Random random = new System.Random();
List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
int defaultValue = -1;
int randomElement = random.FromList(numbers, defaultValue);
In this example, randomElement will be a random number from the numbers list, or -1 if the list is empty.
System.Random random = new System.Random();
List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
int defaultValue = -1;
int randomElement = random.FromList(numbers, defaultValue);
// randomElement will be a random number from the list or -1 if the list is empty.
