Strings.Left Method

Returns a string containing a specified number of characters from the left side of a string.

Namespace: Microsoft.VisualBasic
Assembly: Microsoft.VisualBasic (in microsoft.visualbasic.dll)

Public Shared Function Left ( _
	str As String, _
	Length As Integer _
) As String
Dim str As String
Dim Length As Integer
Dim returnValue As String

returnValue = Strings.Left(str, Length)
public static String Left (
	String str, 
	int Length
public static function Left (
	str : String, 
	Length : int
) : String



Required. String expression from which the leftmost characters are returned.


Required. Integer expression. Numeric expression indicating how many characters to return. If 0, a zero-length string ("") is returned. If greater than or equal to the number of characters in str, the entire string is returned.

Return Value

Returns a string containing a specified number of characters from the left side of a string.

For more detailed information, see the Visual Basic topic Left Function (Visual Basic).

To determine the number of characters in str, use the Len function. If used in a Windows Forms application, or any other class that has a Left property, you must fully qualify the function with Microsoft.VisualBasic.Left.


The LeftB function in previous versions of Visual Basic returns a string in bytes rather than characters. It is used primarily for converting strings in double-byte character set (DBCS) applications. All current Visual Basic strings are in Unicode, and LeftB is no longer supported.

This example demonstrates the use of the Left function to return a substring of a given String. In a class that has a Left property, it may be necessary to fully qualify the Left function.

Dim TestString As String = "Hello World!"
' Returns "Hello".
Dim subString As String = Microsoft.VisualBasic.Left(TestString, 5)
