Use String.IndexOfAny: http://msdn.microsoft.com/en-us/library/system.string.indexofany.aspx

bool specialCharacterIsInString = myString.IndexOfAny(new char[]{'#', '$', '_', '&', '%'}) != -1;

Adjust the characters array so that contains the characters that you consider “special character” in your current context.
