If I understood your question right, this should do:

char delimiter = ...  
string delimiterString = delimiter.ToString();
string s = ...
bool right = !s.Contains(' ') 
  && s.StartsWith(delimiterString) 
  && s.EndsWith(delimiterString)
  && !s.Substring(1,s.Length-2).Contains(delimiter);

Use regex...Assuming # as delimeter and zero characrters between as acceptable.

Regex rx=new Regex("^#+[^\s]*#$");

return rx.IsMatch(teststring);
