Get last 5 characters in a string

Question

I want to get the last 5 digits/characters from a string. For example, from "I will be going to school in 2011!", I would like to get "2011!".

Any ideas? I know Visual Basic has Right(string, 5); this didn't work for me and gave me an error.

Answer 1

str.Substring(str.Length - 5)

Answer 2

Error check:

result = str.Substring(Math.Max(0, str.Length - 5))

Answer 3

Checks for errors:

Dim result As String = str
If str.Length > 5 Then
    result = str.Substring(str.Length - 5)
End If

Answer 4

in VB 2008 (VB 9.0) and later, prefix Right() as Microsoft.VisualBasic.Right(string, number of characters)

Dim str as String = "Hello World"

Msgbox(Microsoft.VisualBasic.Right(str,5))

'World"

Same goes for Left() too.

Answer 5

Old thread, but just only to say: to use the classic Left(), Right(), Mid() right now you don't need to write the full path (Microsoft.VisualBasic.Strings). You can use fast and easily like this:

Strings.Right(yourString, 5)

Answer 6

The accepted answer of this post will cause error in the case when the string length is lest than 5. So i have a better solution. We can use this simple code :

If(str.Length <= 5, str, str.Substring(str.Length - 5))

You can test it with variable length string.

    Dim str, result As String
    str = "11!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)
    str = "I will be going to school in 2011!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)

Another simple but efficient solution i found :

str.Substring(str.Length - Math.Min(5, str.Length))

Answer 7

I opened this thread looking for a quick solution to a simple question, but I found that the answers here were either not helpful or overly complicated. The best way to get the last 5 chars of a string is, in fact, to use the Right() method. Here is a simple example:

Dim sMyString, sLast5 As String

sMyString = "I will be going to school in 2011!"
sLast5 = Right(sMyString, - 5)
MsgBox("sLast5 = " & sLast5)

If you're getting an error then there is probably something wrong with your syntax. Also, with the Right() method you don't need to worry much about going over or under the string length. In my example you could type in 10000 instead of 5 and it would just MsgBox the whole string, or if sMyString was NULL or "", the message box would just pop up with nothing.
