Parameters

str
Type: System.String
Required. Any valid String expression.

Return Value

Type: System.String
Returns a string containing a copy of a specified string with no leading spaces (LTrim), no trailing spaces (RTrim), or no leading or trailing spaces (Trim).

The LTrim, RTrim, and Trim functions remove spaces from the ends of strings.

This example uses the LTrim function to strip leading spaces and the RTrim function to strip trailing spaces from a string variable. It uses the Trim function to strip both types of spaces.

VB
Copy 

' Initializes string.
Dim TestString As String = "  <-Trim->  "
Dim TrimString As String
' Returns "<-Trim->  ".
TrimString = LTrim(TestString)
' Returns "  <-Trim->".
TrimString = RTrim(TestString)
' Returns "<-Trim->".
TrimString = LTrim(RTrim(TestString))
' Using the Trim function alone achieves the same result.
' Returns "<-Trim->".
TrimString = Trim(TestString)
