StringCollection.IList.Add Method (Object)
Adds an object to the end of the StringCollection.
Assembly: System (in System.dll)
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.
