Public Function Left (str As String, Length As Integer) As String
String expression from which the leftmost characters are returned.
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

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