You can use    String TrimStart - Removes all leading occurrences of a set of characters specified in an array from the current String object  String TrimEnd - Removes all trailing occurrences of a set of characters specified in an array from the current String object  String Trim - combination of the two functions above   Usage   string txt                       i am a string                                       char   charsToTrim                txt   txt Trim charsToTrim       txt    i am a string    EDIT   txt   txt Replace              txt    iamastring

Or you can split your string to string array  splitting by space and then add every item of string array to empty string  May be this is not the best and fastest method  but you can try  if other answer aren t what you whant

Use the Trim method

String Trim     Removes all leading and trailing white-space characters from the current String object    Usage   txt   txt Trim      If this isn t working then it highly likely that the  spaces  aren t spaces but some other non printing or white space character  possibly tabs  In this case you need to use the String Trim method which takes an array of characters     char   charsToTrim            t       string result   txt Trim charsToTrim     Source  You can add to this list as and when you come across more space like characters that are in your input data  Storing this list of characters in your database or configuration file would also mean that you don t have to rebuild your application each time you come across a new character to check for   NOTE  As of  NET 4  Trim   removes any character that Char IsWhiteSpace returns true for so it should work for most cases you come across  Given this  it s probably not a good idea to replace this call with the one that takes a list of characters you have to maintain   It would be better to call the default  Trim   and then call the method with your list of characters
