Right Function (Visual Basic)
Returns a string containing a specified number of characters from the right side of a string.
Public Shared Function Right( _
ByVal str As String, _
ByVal Length As Integer _
) As String
Parameters
str
Required. String expression from which the rightmost characters are returned.Length
Required. Integer. 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.
Exceptions

|---|---|---|
Length < 0. |
See the "Error number" column if you are upgrading Visual Basic 6.0 applications that use unstructured error handling. (You can compare the error number against the Number Property (Err Object).) However, when possible, you should consider replacing such error control with Structured Exception Handling Overview for Visual Basic.
Remarks
To determine the number of characters in str, use the Len function. If used in a Windows Form, or any other class that has a Right property, you must fully qualify the function with Microsoft.VisualBasic.Right.
Note
The RightB function in earlier 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 RightB is no longer supported.
Example
This example demonstrates the use of the Right function to return a substring of a given String. In a class that has a Right property, it may be necessary to fully qualify the Right function.
Dim TestString As String = "Hello World!"
' Returns "World!".
Dim subString As String = Microsoft.VisualBasic.Right(TestString, 6)
