Concatenates a specified separator String between each element of a specified StringCollection, yielding a single concatenated string.
A String consisting of the elements of value interspersed with the separator string.
For example if separator is ", " and the elements of value are "apple", "orange", "grape", and "pear", Join returns "apple, orange, grape, pear".
If separator is a null reference (Nothing in Visual Basic), an empty string (Empty) is used instead.
