Well    I would like you to understand more specific areas of space   t is actually assorted as a horizontal space  not a vertical space   test out inserting  t in Notepad   If you use Java  simply use  v  See the reference below       h - A horizontal whitespace character         t xA0 u1680 u180e u2000- u200a u202f u205f u3000         v - A vertical whitespace character         n x0B f r x85 u2028 u2029    But I am aware that you use  NET  So my answer to replacing every vertical space is    string replacement   Regex Replace s      n u000B u000C r u0085 u2028 u2029

If speed and low memory usage are important  do something like this   var sb   new StringBuilder s Length    foreach  char i in s      if  i      n   amp  amp  i      r   amp  amp  i      t           sb Append i    s   sb ToString

I like to use regular expressions  In this case you could do   string replacement   Regex Replace s     t  n  r          Regular expressions aren t as popular in the  NET world as they are in the dynamic languages  but they provide a lot of power to manipulate strings

The right choice really depends on how big the input string is and what the perforce and memory requirement are  but I would use a regular expression like   string result   Regex Replace s     r n   n  t   String Empty     Or if we need to apply the same replacement multiple times  it is better to use a compiled version for the Regex like  var regex   new Regex    r n   n  t   RegexOptions Compiled    string result   regex Replace s  String Empty     NOTE  different scenarios requite different approaches to achieve the best performance and the minimum memory consumption

You want to use String Replace to remove a character   s   s Replace   n   String Empty   s   s Replace   r   String Empty   s   s Replace   t   String Empty     Note that String Trim params char   trimChars  only removes leading and trailing characters in trimChars from the instance invoked on   You could make an extension method  which avoids the performance problems of the above of making lots of temporary strings   static string RemoveChars this string s  params char   removeChars        Contract Requires lt ArgumentNullException gt  s    null       Contract Requires lt ArgumentNullException gt  removeChars    null       var sb   new StringBuilder s Length       foreach char c in s             if  removeChars Contains c                 sb Append c                       return sb ToString
