Trim last 4 characters from string?

Question

How can I trim MyString to be MyStr?

Thanks, google failed again :(

Answer 1

YourString.Left(YourString.Length-4)

or:

YourString.Substring(0,YourString.Length-4)

Answer 2

c#

string s = "MyString";
Console.WriteLine(s.Substring(0, s.Length - 3));

vb.net

dim s as string
s = "MyString"
Console.WriteLine(s.Substring(0, s.Length - 3))

vb.net (with VB6 style functions)

dim s as string
s = "MyString"
Console.WriteLine(Mid(s, 1, len(s) - 3))

Answer 3

Rob's answer is mostly correct but the SubString solution will fail whenever the string has less than 4 characters in it. If the length goes past the end of the string an exception will be thrown. The following fixes that issue

Public Function TrimRight4Characters(ByVal str As String) As String
  If 4 > str.Length Then
    return str.SubString(4, str.Length-4)
  Else
    return str
  End if
End Function
