| Description |
By default, it will remove any leading or trailing blanks from the current string.
If you supply a CharArray then it will remove all such characters from the start and end of the string. The characters can be in any order - removal proceeds at each end until a string character is found that is not in the character array.
|
| | Notes | Like a lot of string methods, the string object itself is not affected - the modified string is returned for assignment.
