If The Character To Split Are 2 Or More Character Instead Of "~"?

i use this code to split a words:

Dim sWord As String = "Word1~Word2~Word3~Word4"
Dim sResult As String() = sWord.Split(New Char() {"~"c}, StringSplitOptions.RemoveEmptyEntries)

so that a messagebox can show

Word1
Word2
Word3
Word4

but how about if the character to split are 2 or more character instead of "~"? because sometimes "~" is used in some documentation.. i prefer to user "!~!" or "D-:" in splitting words..
