How to use the SetValue(,) method of array class in C#?

The SetValue() method sets a value to the element at the specified position in the one-dimensional Array. The index is specified as a 32-bit integer.

Firstly, set the array.

Array arr = Array.CreateInstance(typeof(String), 6);

No set values to the element using the SetValue() method.

arr.SetValue("One", 0);
arr.SetValue("Two", 1);
arr.SetValue("Three", 3);
arr.SetValue("Four", 4);
arr.SetValue("Five", 5);

The following is an example showing the usage of SetValue() method in C#.
