To remove an element from an array in C#, you can use the Array.Copy method to copy the elements of the array to a new array, excluding the element to be removed.
we have an array arr with 5 elements. We want to remove the element 3 from the array. We create a new array newArr with one less element than the original array. We then loop through the original array, copying all elements except the one to be removed to the new array. The new array is then printed to the console.
