C# Array Methods

C# provides built-in methods and properties to manipulate arrays efficiently. Commonly used methods include Length, Reverse(), Sort(), and more.

Key Topics

1. Array Length Property

Example: Getting the Length of an Array

int[] numbers = { 5, 3, 8, 1, 2 };

Console.WriteLine("Length: " + numbers.Length);  // Outputs "Length: 5"

2. Reversing an Array

Example: Using Array.Reverse()

Array.Reverse(numbers);

Console.WriteLine("Reversed Array:");
foreach (int num in numbers)
{
    Console.WriteLine(num);
}

3. Sorting an Array

Example: Using Array.Sort()

Array.Sort(numbers);

Console.WriteLine("Sorted Array:");
foreach (int num in numbers)
{
    Console.WriteLine(num);
}

Key Takeaways

  • Length property gives the number of elements in the array.
  • Array.Reverse() reverses the elements of the array.
  • Array.Sort() sorts the array elements in ascending order.
  • Utilizing array methods simplifies data manipulation tasks.
