Returns a copy of string with all leading and trailing spaces
deleted if it succeeds and the empty string (“”) if an error occurs. If
string is null, Trim returns null.
Usage
Trim is useful for removing spaces that a user may have typed before
or after newly entered data.
If you do not include the optional removeallspaces argument or its
value is false, only the space character (U+0020) is removed from the
string.
If the removeallspaces argument is set to true, all types of space
characters are removed. See LeftTrim
for a list of space characters.
Examples
This statement returns BABE RUTH if all the leading and trailing
spaces are space characters:
|
1 |
Trim(" BABE RUTH ") |
This statement returns BABE RUTH if the leading and trailing spaces
include other types of white space characters:
|
1 |
Trim(" BABE RUTH ", true ) |
This example removes the leading and trailing spaces from the
user-entered value in the SingleLineEdit sle_emp_fname and saves the value
in emp_fname:
|
1 2 |
string emp_fname emp_fname = Trim(sle_emp_fname.Text) |
