title: Remove pluses, dashes, colons using REGEX and C#
body: <p>I need to remove these occurrences in a document using REGEX and C#. They are:
  +-------------+ (there can be any number of dashes between plus signs)
  :             : (there can be any number of spaces between colons)
  I cannot remove standalone dashes or semi-colons since they may come after Name: or Address: and are needed. I cannot remove a colon between words with a space on either side. The colon with spaces creates formatting that I need to remove. The plus with dashes in-between creates a line or part of a box that I need to remove.</p>
  
  <p>Basically, I need to remove all dashes with pluses at the ends, including removing the pluses. I also need to remove all spaces with colons at each end, including removing the colon. All other pluses and colons need to remain. This is a medical text file so I need to be careful. I do not have any code to show you since nothing I have tried has come close to working.
  Thanks for any assistance!</p>
