ExceptionCondition
NotSupportedException

The StringCollection is read-only.

-or-

The StringCollection has a fixed size.

StringCollection accepts null as a valid value and allows duplicate elements.

If Count already equals the capacity, the capacity of the StringCollection is increased by automatically reallocating the internal array, and the existing elements are copied to the new array before the new element is added.

If Count is less than the capacity, this method is an O(1) operation. If the capacity needs to be increased to accommodate the new element, this method becomes an O(n) operation, where n is Count.
