C# – Changing the Length of an Array

We continue with array. This time how we change the length of an array.

Arrays are immutable = cannot be changed in memory. However .Net Framework providers helper methods to resize an array… creates a new array and copies the old values into it.

Array.Resize(ref myArray, myArray.Length + 1);

//Get the highest index:

int highestIndex = myArray.GetUpperBound(0);

// 0 = dimension we want to retrieve the upper boundary for

//Arrays have other helper methods

myArray.Sum();

myArray.Min();

myArray.Max();

myArray.Average();

Array.Sort(myArray);

Array.Reverse(myArray);
