public void SetValue (object value, long index)

Parameters

value
The new value for the specified element.

A 64-bit integer that represents the position of the Array element to set.

Remarks

The Array.GetLowerBound(int) and Array.GetUpperBound(int) methods can determine whether the value of index is out of bounds.

This method is an O(1) operation.

Note:

If erload:System.Array.SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. The value of the element is not a null reference, and cannot be found by searching for a null reference.
